A six-week scheme to carry out improvements at Morpeth’s historic Telford Bridge has got under way.
It will involve re-pointing the underside of the arches and the bridge faces as well as strengthening work to the stone parapets.
The bridge was built between 1829 and 1831.
To enable the works to be carried out safely in the later stages of the scheme, temporary traffic lights will be in place on a limited number of occasions between 7pm and 10pm on weekday evenings and from 7am to 10am on Sunday mornings to allow the masonry units to be lifted in place.
At these times, likely to only be in the last two weeks of the scheme, only one lane of the bridge, along with the adjacent footway, will be closed.
Vehicles will continue to use the remaining traffic lane to cross the bridge.
Pedestrians can either use the other footway or adjacent footbridge to get to and from the town centre.
Outside these times, the bridge will be fully open.
The improvements form part of a £6.7million county-wide scheme to better the condition of 130 masonry arch bridges. It is mainly being funded nationally following a successful bid by Northumberland County Council to cover the cost of the repair work.
The local authority has also contributed just over £1million towards the scheme.
Head of technical services David Laux said: “Telford Bridge is one of the key routes into Morpeth and it is important it is kept in good condition.”
