The diversion of West Bromwich’s A41 expressway has got under way, as the first sod was cut by officials.
The project will reduce congestion, according to planners on Sandwell Metropolitan Borough Council.
Contractor Balfour Beatty was chosen for the £25M road project, £22.2M of which is being paid for by the Department for Transport.
Running beside the town centre to junction 1 of the M5, the A41 expressway will be diverted under the “fire station” roundabout at the junction of the A4031 All Saints’ Way.
The roundabout will be made a different shape, while new paths and cycle lanes will be installed.
The project is scheduled to finish by late 2011 to coincide with the opening of a Tesco supermarket - the retail giant is putting £2.2M towards the road diversion.
The town centre and All Saints Way will be linked with a new footbridge.
