Part of the M1 in Sheffield is to be closed overnight as maintenance work is carried out on the Tinsley Viaduct. Work on the two-tier bridge, which carries the M1 over the A631, will mean the closure of both carriageways at junction 34. The Highways Agency expects work to be completed by 14 March and warns of some delays. It believes that the work will reduce the need for future emergency repairs and lane closures.
