Works on the first phase of the new A1331 link road have begun, which will provide three new roundabouts as future access to the new garden community.
Councillor Lee Scott, Cabinet Member for Planning a Growing Economy, and Councillor Lesley Wagland, Deputy to the Leader at Essex County Council, joined other guests to take the first ceremonial spadefuls of earth to mark the start of main construction.
Funded as part of a £99 million package of investment by Homes England, which also includes the Colchester Rapid Transit System, phase one of the A1331 is the first piece of infrastructure to directly support the future delivery of the new Tendring Colchester Borders Garden Community.
The 16-month project, which is being constructed by Octavius Infrastructure, will result in three new roundabouts as future access to the new garden community.
There will also be a 1.8km cycleway, provision for pedestrians and horse riders, and ecological measures including 47,000 plants.
