Salisbury Road Bridge now closed 24/7 until 7am Monday 21 September

We had planned to re-open Salisbury Road Bridge on the morning of Saturday 19 September.

However, we recently discovered defects in the concrete underneath the road surface we're replacing.

To repair these defects, we now need to keep Salisbury Road Bridge closed until 7am Monday 21 September.

Unfortunately, the extended closure is unavoidable. We apologise for any inconvenience and thank you for your patience.
