Brightwells developer Crest Nicholson closed an eastbound lane of the bypass between Red Lion Lane and the Shepherd and Flock roundabout on January 8 for the construction of a temporary bridge linking its construction site to the A31.
This was set to be in place for six weeks - potentially taking the works up to February 19.
However, the Herald understands the highways works have now been completed, meaning the lane can soon reopen subject to the results of a road safety audit set to be undertaken later this week.
Once the bridge is in place, the next phase of the Brightwells redevelopment will be to start demolition works – with the Redgrave Theatre one of the first to go.
