Notice of overnight road closures A413, London Road, Small Dean

What we are doing

We will be undertaking multiple works at the Small Dean viaduct to prepare for the viaduct launch in early 2025.  We will complete trial holes in the verge of the road and commence the lifting of hammerhead units for the construction of the final pier.  As we need to protect the safety of our team working close to the carriageway, the A413, London Road will be closed for the duration of our works.

Update for December closures

We will need to extend the overnight road closures into December to install a new barrier that meets the curvature of the road.

For the dates and map of the work location please see the notification below.
