On the closure, the National Highways said: "We understand that these closures cause disruption to road users and local communities, and we’re striving to keep the bridges open as often as we can.

"Our work isn’t always visible. We may be carrying out repairs underneath the road surface, or waiting for construction materials to dry or set before continuing our work."

The carriageway will be reopened at 6am on Thursday, April 18, 2024.

Works will also be carried out on Thursday evening, with the closure operating between 10pm and 6am on Friday morning.
