Devon County Council engineers and contractors have completed the repairs to Shaldon Bridge.
Work to pour concrete around the defective pier, in order to strengthen the 89-year-old structure, went ahead last week.
The teams had to contend with difficult conditions and divers worked until the early hours of Friday morning in zero visibility to carry out the repairs.
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 remediation work was agreed in November and was carried out by contractor TMS of Teignmouth.
Devon County council cabinet member for highway management Stuart Hughes said: “Thanks must go to the contractor, TMS of Teignmouth, and our own engineers who have all worked tirelessly through some atrocious weather conditions. We appreciate the patience of the local community and thanks to everyone for bearing with us. Conditions have been against us but we’ve ensured that we’ve made this repair happen as quickly as possible.”
Concrete samples were taken and will be tested this week to see if it has reached the desired strength to be able to remove the weight restriction on the bridge.
