Advanced preparations to replace a viaduct over the river Chelmer in Chelmsford in Essex are due to start today.
The replacement of the existing viaduct is necessary as the bridge is in a poor condition and is deteriorating. If no action is taken then the A138 could become subject to weight restrictions and eventual closures.
The scheme which is part of a £28 million investment programme will involve the construction of the new viaduct and the demolition of the existing viaduct, building three lanes of carriageway, a shared footway and cycleway and a new footpath.
Today advanced works will begin for the main access site to be constructed off Chelmer Village Way. The works will involve realignment of road kerbing and footpath, surfacing of Bell mouth, establishing a site compound and altering existing street lighting.
The advanced works will take place over 10 days from 8am until 6pm and lane one westbound will be closed from Beeleigh Link roundabout to Chelmer Way roundabout.
The main works are due to start in February subject to weather conditions and will take approximately 18 months to complete.
