This £28 million investment 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.
Once completed in winter 2016, this Highways Agency project will reduce congestion and make the route safer.
Highways Agency East Regional Director, Catherine Brookes, said:
Building a new viaduct and demolishing the old one demonstrates our commitment to improving our road network and helping to stimulate growth.
Extra capacity along the viaduct will deliver significant economic benefits for both local businesses and motorists while helping to improve road safety.
The existing Chelmer Viaduct is in a poor condition, although we’re content it remains safe for use at the moment.
We have worked hard with our contractor to plan the work carefully to minimise disruption and are engaging with those affected to ensure they’re aware of the work.
Alan Bill, Managing Director of GRAHAM Construction, said:
GRAHAM are delighted to be working with the Highways Agency to safeguard the A138 as a strategic highway link.
Throughout the duration of this project we, as we do on all of our contracts, will work with the local supply chain and use subcontractors and suppliers from across the region as well as engaging with the local community to ensure there is minimal disruption during the course of this project.
The advanced works were completed on 26 January and now the main works will begin. This will involve building foundation works for the bridge in both directions, a temporary bridge and haul road near the Old Navy roundabout will be constructed for the works materials and construction traffic to be transported and cable, sewage and water works will start.
The majority of the work will be carried out offline. More details will be announced as and when required.
