Work to lower the carriageway under the three bridges between Mancetter roundabout and Long Street junction.
This work is required to create extra room for tall vehicles to pass underneath.
The works will be carried out overnight when there are fewer vehicles on the road.
During the day the carriageway will be kept open using a contraflow system. This is where traffic travelling in both directions uses one side of the road while we carry out work on the other side.
