This comes as thousands of people head into the city to take part in the Great South Run this morning.

Work has included the removal of the old road surface and waterproofing on the top of the westbound bridge, and upgrading the existing surface drainage was completed over two previous weekend closures.

On top of this, work has also been carried out underneath the two bridges, as well as on the eastbound carriageway. This weekend’s closure will be followed by overnight closures between November 3 to 11.
