Project information

Overview

The bridge that carries the A27 Havant Bypass over the Portsmouth to London railway line, near Cosham/Drayton, was constructed in 1968 and requires essential repairs.

We will be carrying out work to replace the bridge joints and waterproofing material, resurface the eastbound and westbound carriageways and replace the central reservation over the bridge.

Works will take place in two main phases comprising of two full weekend closures of the A27 carriageway over the bridge, followed by narrow lanes running with a 50mph speed restriction on the A27 carriageway over the bridge for up to 10 weeks.

There will also be occasional overnight closures of the A27 across the bridge from between 9pm and 6am.

The weekend closures are required to allow materials to harden across the carriageway. These works are highly weather dependant, so the dates below may therefore be subject to change:

  • Friday 18 September from 9pm through to Monday 21 September at 6am –A27 eastbound carriageway between junction 12 of the M27 and the A2030 Eastern Road roundabout
  • Friday 25 September from 9pm through to Monday 28 September at 6am –A27 westbound carriageway between the A2030 Eastern Road roundabout and the Portsbridge roundabout

Should the works not be completed as scheduled, further closures will take place over the first two weekends in October 2020.

These essential repairs will ensure the long-term safety for road and rail users.
