As Highways Authority, the Council also has an interest in other owner structures that span or support the highway, which include 724 bridges. Highway structures include bridges, culverts, subways, footbridges, retaining walls and miscellaneous structures such as reinforced earth embankments, sea walls, rockfaces and cuttings, sign and signal gantries, and traffic signal masts. In addition to the Highway structures, the Council owns Public Rights of Way (PROW) structures which are discussed in Annex 10 \u2013 Public Rights of Way.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The Engineering Design Group (EDG) Bridges and Structures Group is part of the Climate Change, Environment and Transport Group of the Council and provides the following services:<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span data-contrast=\"auto\">Bridges and Structures Asset Management,<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n\n\n\n<li><span data-contrast=\"auto\">Bridge and Structures Inspection and Maintenance,<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n\n\n\n<li><span data-contrast=\"auto\">Design of new Highway and Cycleway bridges and structures, and<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n\n\n\n<li><span data-contrast=\"auto\">Technical Approval Authority (TAA).<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n<\/ul>\n\n\n\n<p><span data-contrast=\"auto\">In accordance with the National Code of Practice \u2018Well-Managed Highway Infrastructure\u2019<\/span><span data-contrast=\"auto\">1<\/span><span data-contrast=\"auto\"> the following highway structures are the responsibility of the EDG Bridges and Structures Asset Management Team:<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span data-contrast=\"auto\">Council bridges (footbridges, subways, underpasses, tunnels, cellars, vaults, culverts, pipes etc) with a span of 1.5m or more,<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n\n\n\n<li><span data-contrast=\"auto\">Retaining walls associated with the highway with a retained height of 1.35m or more, and<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n\n\n\n<li><span data-contrast=\"auto\">Gantries \/ cantilever structures \/ masts for signage, CCTV and traffic signals classed as a structure in CS 450 \u2013 Inspection of highway structures<\/span><span data-contrast=\"auto\">2<\/span><span data-contrast=\"auto\">,<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n<\/ul>\n\n\n\n<p><span data-contrast=\"auto\">In addition to the above, the EDG Bridges and Structures Asset Management Team are also responsible for the following:<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span data-contrast=\"auto\">Corrugated steel pipes with a span of 0.9m or more, and<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n\n\n\n<li><span data-contrast=\"auto\">Specific culverts with a span of less than 1.5m that are considered by the Flood Risk team to present a significant flood risk should they block.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/li>\n<\/ul>\n\n\n\n<p><span data-contrast=\"auto\">Data on the actual current condition and performance of assets is obtained from inspections, testing and monitoring and assessment of structures.

This work has ensured that maintenance strategies and annual maintenance programmes of work focus on high risk and critical condition structures on key networks such as the Resilient Network and Major Road Network (MRN).&nbsp;&nbsp; Increasing pressure on budgets and resources combined with external factors such as climate change means that achieving asset management objectives and the levels of service that deliver a road network which is as safe, reliable and as fit for purpose as possible is becoming more challenging.

The Council owns 94 clapper bridges, the majority of which have an assessed capacity less than 40T (3 \u2013 38T). The load carrying capacity of clapper bridges is difficult to assess reliably because of the dimensional and material property variability of the individual units. A conservative model is used for the assessment combined with conservative material properties resulting in very low load capacities that are far below the vehicle loadings that the bridges will have carried over many years of use without signs of failure. Some clapper bridges have been strengthened where they carry higher class roads that have greater traffic flows. The remainder carry lower class routes, and as they are small span structures with generally low headroom, they are considered at low risk of failing.&nbsp;&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><span data-contrast=\"none\">B4: Overdue Bridge General Inspections (GI\u2019s)<\/span><span data-ccp-props=\"{&quot;134245418&quot;:true,&quot;134245529&quot;:true,&quot;201341983&quot;:0,&quot;335559738&quot;:40,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/h5>\n\n\n\n<p><span data-contrast=\"auto\">Attention has been focussed on reducing the number of overdue bridge GI\u2019s.&nbsp; In 2018 there were 1268 Bridge GI\u2019s overdue (in excess of the 2-year inspection interval), which has been reduced to 438 as of June 2022.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><span data-contrast=\"none\">B5: Risk Management Approach for Bridge Principal Inspections (PI\u2019s)<\/span><span data-ccp-props=\"{&quot;134245418&quot;:true,&quot;134245529&quot;:true,&quot;201341983&quot;:0,&quot;335559738&quot;:40,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/h5>\n\n\n\n<p><span data-contrast=\"auto\">As stated in Section 2, the Council has adopted a risk-based approach to PI\u2019s to increase the inspection interval on non-critical structures in accordance with the risk-based approach described in Chapter 8 of CS 450<\/span><span data-contrast=\"auto\">2<\/span><span data-contrast=\"auto\">.

As stated above, identified safety critical works are undertaken in year as soon as possible either using the Revenue or Capital budgets depending on the type of work or temporary restrictions are put in place until the works can be carried out. If budget is unavailable, other schemes are deferred to allow the safety critical works to be undertaken.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">Where possible schemes are grouped and\/or coordinated with other highway infrastructure asset schemes to provide cost savings in delivery.

Greater occurrence of flooding is increasing the risk of bridges being washed away and damage due to scour of bridge foundations. As experience shows from the 2009 flooding events in Cumbria, loss of bridges causes major disruption to communities and businesses. In Devon several bridges have collapsed due to damage following flooding, such as Waterstave and Collard Bridges in 2012. The Council\u2019s bridges identified at potential risk of scour following a flood event are surveyed and assessed to ensure that foundations are investigated and protected or the risks managed.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">EDG Bridges and Structures Asset Management Team has undertaken a programme of Stage 1 assessments in accordance with BD 97\/12 \u2013 The Assessment of Scour and Other Hydraulic Actions at Highway Structures<\/span><span data-contrast=\"auto\">14<\/span><span data-contrast=\"auto\">. This work has now progressed to carrying out Stage 2 assessments where specific works are proposed.&nbsp; The impact of debris accumulation on bridges during flood events, which is known to cause scour, is also being investigated.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">During major flooding incidents when a number of bridges may be seriously damaged, the Bridges and Structures Emergency Plan, which is under development, will come into effect.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">Investment in highway surface water drainage systems is required to minimise damage to highway embankments and retaining walls. Extreme rainfall events cause surface water to wash away embankments, which support the highway, requiring significant repairs including new retaining walls and other structural solutions to shore up the highway.&nbsp; This is an expensive and disruptive process and can be avoided if preventative actions such as maintaining and improving highway drainage systems are implemented.&nbsp; Future policies and preventative actions are required to ensure the highway network can cope with more frequent extreme weather events due to climate change.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"7-2-defects-in-hidden-bridge-components\">7.2 Defects in Hidden Bridge Components<\/h3>\n\n\n\n<p><span data-contrast=\"auto\">Two high profile cases in recent years have emphasised the importance of defects in hidden bridge components. In 2009, the Stewarton rail bridge, Ayrshire collapsed during passage of a freight train.&nbsp; Corrosion to half-through girder webs was so severe that complete loss of section had occurred in areas of high shear load. The corroded areas were hidden under ballast and had not been inspected. The A4 Hammersmith Flyover on one of London\u2019s busiest roads, had been subject to limited inspections of its post-tensioning tendons since the mid-1990s. During investigation works in 2011, two of the eight tendons over one particular pier were found to be badly corroded and the flyover was closed while further investigation of the remaining six tendons and assessment was undertaken. The flyover was reopened with restricted traffic loading while emergency strengthening works were undertaken before the implementation of a full strengthening scheme. The full strengthening works, plus bearing and joint replacement, were completed in 2015 at a cost in the order of \u00a3120m.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">CIRIA has recently published C764 \u2013 Hidden defects in bridges: Guidance for detection and maintenance<\/span><span data-contrast=\"auto\">15<\/span><span data-contrast=\"auto\">. EDG engineers will use the document to review and update current inspection practices, and to start a hidden defects programme to identify hidden components in bridges.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"7-3-funding\">7.3 Funding<\/h3>\n\n\n\n<p><span data-contrast=\"auto\">The Council is facing unprecedented financial pressures and with current high inflation this is impacting available funding and increasing the construction cost of schemes. Any further reduction in the BAS budget will mean the bridge condition is unlikely to be improved and it is more likely they will continue to deteriorate with potential for weight restrictions or closures at some point in the future.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">Failure to maintain the Council\u2019s highway structures will result in the structures residual life reducing with potential need to replace sooner.\u202f Depending on the period of time and severity of the reductions, it could eventually result in closure of some bridges as it would not be possible to maintain them in a safe state and an escalation of costs to claw back the condition of other structures in future years.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">Major investment in upgrading the Exeter Bridge Road Canal Bascule and Swing bridges is required within 5 years.\u202f Without this investment the bridges will become more unreliable for canal openings and, it is likely a weight restriction on the Bascule bridge will be required within 10 to 20 years. A bid to the Department for Transport (DfT) has been made for to upgrade the bridges and to undertake further improvements to Bridge Road.\u202f If this bid is unsuccessful the implications are additional funding will be needed within 5 years to refurbish or replace the existing bridges.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"7-4-bridge-safeguarding\">7.4 Bridge Safeguarding<\/h3>\n\n\n\n<p><span class=\"NormalTextRun SCXW196845331 BCX8\">It is a sad reality that bridges in Devon have been used to end life by suicide<\/span><span class=\"NormalTextRun SCXW196845331 BCX8\">.&nbsp;&nbsp;<\/span><span class=\"NormalTextRun SCXW196845331 BCX8\"> Two major bridges in North Devon crossing the Rivers Taw and Torridge have had their parapets replaced with higher ones and to date the evidence is they have had a significant impact in reducing the number of incidences at these locations.

Members of the public complain of unsightly appearance, offensive material and of feeling intimidated when walking through <\/span><span class=\"NormalTextRun SCXW159423558 BCX8\">badly affected<\/span><span class=\"NormalTextRun SCXW159423558 BCX8\"> subways or <\/span><span class=\"NormalTextRun SCXW159423558 BCX8\">retaining<\/span><span class=\"NormalTextRun SCXW159423558 BCX8\"> walls in urban areas. One option for dealing with graffiti is regular removal or overpainting in the hope that those responsible will lose interest and either desist or move elsewhere. This however can be a costly approach with weekly visits by cleaning teams needed in heavily used areas such as the subways at Exe Bridges in <\/span><span class=\"NormalTextRun SCXW159423558 BCX8\">Exeter.<\/span><\/span><span class=\"EOP SCXW159423558 BCX8\" data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"11-1-3-removal-of-offensive-material\">11-1.3 Removal of offensive material<\/h3>\n\n\n\n<p><span data-contrast=\"auto\">There is a need to quickly remove offensive material such as swear words, racist remarks and obscene drawings. This is usually best achieved by painting over the offending material as soon as it is reported and then programming a graffiti removal task. Structures that are frequently targeted will usually have an anti graffiti coating applied; it is important to check the structure records to identify the product so that the correct removal process can be used.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The two main methods of removal are high pressure water jetting and the use of chemicals. Care must be taken not to pollute the environment with chemicals or effluent from the water jetting operation which may contain paint or other contaminants. Removal operations can usually be carried out without restricting public access totally but a safety zone must be used to minimise public risk.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">After the removal operation it will usually be necessary to reapply an anti graffiti barrier.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"11-1-4-anti-graffiti-coatings\">11-1.4 Anti-graffiti coatings<\/h3>\n\n\n\n<p><span data-contrast=\"auto\">If existing structures are being affected by graffiti the area Bridge Inspector will recommend a treatment process to the Principal Engineer Bridge Maintenance (PE (BM)) who will assess the cost implications and if necessary, add to the revenue programme.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">New structures that will become the responsibility of the <\/span><span data-contrast=\"auto\">Council<\/span><span data-contrast=\"auto\"> will receive a maintenance audit by the PE (BM) when graffiti protection using a surface finish such as \u2018knocked off rib\u2019 on walls to create an uneven surface or proprietary coatings to make it easier to remove graffiti will be considered.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"11-1-5-use-of-street-art-and-murals\">11-1.5 Use of street art and murals<\/h3>\n\n\n\n<p><span data-contrast=\"auto\">The application of murals and street art is growing in popularity in Devon and can considered for reducing the occurrence or impact of graffiti. The benefits are many including reduced cost to the <\/span><span data-contrast=\"auto\">Council<\/span><span data-contrast=\"auto\"> for cleaning operations, involvement of local community groups particularly schools and art colleges and the creation of a more pleasant environment.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The materials used for murals and street art should be carefully considered and agreed with the PE (BM). Whilst damage to a structure from the application of paint is unlikely, it is often sensible to use water based or low volatile content paints to ensure the existing structure is not damaged or the anti carbonation treatment on surfaces is not compromised.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The content of the art work should also be carefully considered to ensure it cannot easily be defaced; the adding of appendages or speech balloons are two common ways to ruin a piece of street art.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">It is quite common for local organisations or individuals to volunteer to paint subways and other structures as a school\/college art project. This can work but the scale of the task involved can be under-estimated. The Tarka Trail scheme shown at the end of this paper was one such project. A local 6<\/span><span data-contrast=\"auto\">th<\/span><span data-contrast=\"auto\"> form college had a competition amongst the students to create suitable designs for two newly opened subways that were being targeted. The <\/span><span data-contrast=\"auto\">Council<\/span><span data-contrast=\"auto\"> provided the materials and pedestrian management for what was expected to be a two week project. It soon became apparent that the students would not complete the task and the <\/span><span data-contrast=\"auto\">Council<\/span><span data-contrast=\"auto\"> had to take over. The cost of using contracted services for this type of operation is not insignificant.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The second example of Renslade Subway was carried out by a street artist at no cost to The <\/span><span data-contrast=\"auto\">Council<\/span><span data-contrast=\"auto\"> and was completed in just over a week so volunteers should be encouraged provided they fully understand the task involved.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"11-1-6-consultees-prior-to-new-street-art-murals\">11-1.6 Consultees Prior to new street art\/murals<\/h3>\n\n\n\n<p><span data-contrast=\"auto\">Street art on <\/span><span data-contrast=\"auto\">Council<\/span><span data-contrast=\"auto\"> owned structures does not require planning permission, however it is advisable to liaise with various parties to ensure stakeholders are aware of the project.
