More delays expected at the M27/A27 interchange this weekend with eastbound closure for massive bridge upgrade project

The eastbound M27 will be closed by National Highways at the Cosham / Hilsea interchange from 9pm on Friday (October 10) until 6am on Monday, October 13. This will be followed by a second weekend of eastbound closures from October 17 to 20, and overnight closures from November 3 to 11.

This is to allow for works to continue for the ongoing project to upgrade the bridges at the major interchange which links the M27 with the A27 and the M275. It will also impact traffic heading north on the M275 which would then join the M27/A27 towards Havant.

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. Work also continues underneath the two bridges, as well as on the eastbound carriageway.

Emma Weston, project manager at National Highways, said: “Our workforce has made great progress, and we’ve also been very lucky with the weather. We’re hoping that luck continues to hold, as adverse conditions can impact our work schedule – so do check your journey before setting off.

“We are currently working overnight installing the new expansion joints on the westbound bridge and will also install these on the eastbound bridge once the weekend closures are completed.”
