A project to resurface a two-mile section of the A14 in Cambridgeshire moves to a new phase this month.
Work on the northbound carriageway between the Spittals interchange and Alconbury is now complete and, from Wednesday 8 July, will move to the southbound carriageway.
The work will take place overnight and is expected to continue for four weeks.
During the work, which includes carriageway resurfacing and patching, the renewal of road markings and road studs, the carriageway will only be closed overnight between 8pm and 6am.
A clearly signed diversion route will be in place during the closures, with traffic diverted from the A1(M) at junction 14 to continue along the A1 southbound to A1/A14 Brampton Hut Interchange and join the eastbound A14 to junction 23 Spittals Interchange.
The work is dependent on suitable weather conditions, and dates may be subject to change.
