Where & Why?

A bridge deck expansion joint at Kneeshaw Lupton Bridge is failing and needs urgent investigation.

The recent works to construct a cross over point at Rainbow bridge were required to enable contraflow for the eventual replacement of the joint. This work is to investigate the joint and to prepare for a temporary holding repair currently planned for Saturday night 22nd April.

Diversions & Safety Measures

To undertake this work the westbound carriageway will be closed between Junction 23 at Llanddulas and J22 at Old Colwyn from 11pm on Tuesday 11 April until 6am on Wednesday 12 April. Traffic will be diverted onto a signed diversion route via the A547.
