MOTORISTS travelling south across the Thelwall Viaduct are being warned the road will be shut from 10pm tonight.

The closure comes as work to complete the removal of contraflow roadworks is carried out after work to replace bridge joints finishes.

The northbound side was removed on Sunday night and now between junction 21A and 20 the road will be closed southbond until 5am tomorrow morning.

Joint replacement work is still required on the northbound exit slip road at junction 21 which will take the project into June but this will be limited to occasional overnight lane and slip road closures at weekends.

A clearly-signed diversion will be in place from junction 21A tonight.
