REPAIRS are taking place to the bridge over the A34 at Three Maids Hill, in Winchester, with narrow lanes and overnight closures set to be imposed.

Work is expected to begin next week on the bridge which carries the A272 over the A34 to improve the longevity of the bridge and ensure safety.

Specialist scaffolding will be in place below the bridge, and to allow Highways England teams to be on elevated platforms to reach the areas to be repaired.

Narrow lanes and a 50mph speed limit will be in place on the A34 northbound and southbound carriageways for the duration of the repairs. There will also be a lane closure and a 30mph speed limit on the A272 in both directions across the bridge.

In addition, the A34 southbound carriageway will be closed overnight for a 16-week period, followed by the A34 northbound carriageway which will be closed overnight for a nine-week period. All closures will be between 9pm and 6am, Monday to Friday nights only.

The closures scheduled are:

  • The A34 north and southbound carriageways between the A303 Bullington Cross and the A33 Kings Worthy link will be closed overnight on Tuesday, May 4.
  • The A34 southbound carriageway will be closed overnight between the A303 (Bullington Cross) and the M3 (junction 9) from Wednesday, May 5 through to Friday, August 13. Traffic will be diverted via the A303 and M3; non-motorway vehicles will divert via the A303 and A33.
  • The A34 northbound carriageway will then be closed overnight beneath the bridge only from Monday, August 16 through to Friday, October 15. Traffic will be diverted off the A34 via the exit slip road at the junction, around the Three Maids Hill roundabout, then re-join the A34 via the northbound entry slip road.

Clearly signed diversions will be in place using the A303 and A33 for light and non-motorway vehicles and via the A303 and M3 for HGVs and motorway permitted vehicles.

Work is expected to start May 4 and should be completed by November 2021.
