Two bridges which go over the A1(M) will be affected by roadworks which started today and are expected to be in place for over a month.

Temporary traffic lights are in place at Baldock Lane and Norton Road while the bridges which cross the motorway between Junction 9 for Letchworth Gate and 10 for Baldock Services are looked at by engineers.

The work, which will take place both during the day and overnight, is scheduled to be finished by March 13.

The A1(M) itself is not affected.
