A390 Newbridge, Gunnislake
The historic bridge, which carries the A390 over the River Tamar on the Devon and Cornwall border, has been closed since being struck by a vehicle on Tuesday 2 April.
The 100 metre long (approx.) bridge linking Devon and Cornwall stands over a 3 metre deep stretch of the river Tamar. It means that conventional scaffold, from the ground up, would be challenging for a number of reasons including a risk that branches or other floating debris could destabilise it. So the team has built a cantilever scaffold, from above, which uses weight on one side to counterbalance the weight of engineers and equipment on the other.
Initial assessments of the damage have been conducted and stonemasons are working from the cantilever scaffold to carry out repairs. Around six metres of the parapet wall of the bridge and two of the refuges have been removed and are being rebuilt.
Because the structure, which dates from 1520, is Grade 1 Listed, contractors working on behalf of Devon County Council are ensuring that repairs are carried out sensitively.
The full diversion route that has been signed is 26 miles, which we realise is significant, however we must use roads of the same classification, however there are shorter alternative routes that local residents will be able aware of and use.
Plymouth City Council have provided an update with regards to 79/79A bus and the emergency timetable can be found here.
