Devon County Council has said the concrete pour for the timber piles found below piers on Shaldon Bridge will go ahead later today.
Shaldon Bridge, which carries the A379 over the River Teign, was been subject to weigh restrictions and traffic management since council investigations revealed that plans it held for the structure’s foundations did not match as built conditions.
The original construction drawings show that the bridge’s piers are each made up of four concrete piles, which are encased in steel and concrete. However, the inspection unexpectedly revealed that one of the piles inside a pier was made from timber instead of concrete, which has started to deteriorate.
The closure, which will take place today 6.30pm to 10.30pm, will enable concrete to be poured around the bridge pier support.
Work has already been carried out last week to fix a 3.7t steel pipe around the damaged pier of the Grade II listed structure. The pipe was brought in by barge and clamped into position.
Concrete will now be poured into the pipe to reinforce the supporting piles.
The County Council hopes to be able to remove the 3t weight restriction in the coming weeks, once the concrete has had time to cure.
Devon County Council cabinet member for highway management Stuart Hughes said: “We’re hoping the elements are with us this time so that we can get on with this essential repair. It’s not ideal that we’re having to close the bridge during the week but this is being done during the evening after peak travel time in order to minimise disruption as much as possible.
“We’re as keen as everyone else to get this bridge back to taking heavier loads as soon as possible.”
The remediation work was agreed in November and is being carried out by contractor TMS of Teignmouth.
