MOTORWAY users are being warned of overnight closures on the Thelwall Viaduct this weekend.

Overnight safety work will be taking place along the M6 southbound to allow for National Highways to replace two damaged bridge joints on the carriageway.

Three out of four lanes between junction 21, Woolston, and junction 20, Lymm, will be closed between 7pm on Saturday and 10am on Sunday.

The southbound entry slip road at junction 21 will also need to close during the same period due to the proximity of one of the bridge joints. 

Drivers wishing to join the southbound M6 at junction 21 should instead join the northbound carriageway, travel up to and exit at junction 22 and then access the southbound M6 via the junction roundabout.

While the lane and slip road closures are expected to be lifted by 10am on Sunday, drivers are encouraged to check traffic conditions before setting out on journeys. 

They are also advised that at times they may not see people working in the area - while roadworkers should have completed their repairs in the early hours of Sunday morning, the concrete used to secure the bridge joints will need several hours to cure before lanes and the entry slip road can re-open.
