Roadworks will be carried out over nine weeks, from Thursday, September 24 to Friday November 20, on the A1, between Wyboston and Buckden.
This will be between the hours of 8pm to 6am on weeknights, subject to weather conditions.
Due to the extensive amount of work on this project, Highways England has split the works into four phases.
Diversion routes Phase 1: A1 Wyboston Interchange, northbound exit slip road from September 24 to Tuesday September 29 for four nights.
Northbound traffic wanting to leave the A1 at Wyboston will continue to the Hail Bridge junction and return southbound to the A1/A428 Wyboston Interchange.
Phase 2: A1 / A428 Wyboston Interchange, northbound and southbound entry slip roads from Wednesday September 30 to Monday October 5 for 4 nights.
Traffic wanting to join the A1 northbound and southbound at the Wyboston Interchange will be diverted along the A428 eastbound onto the Barford Road to re-join the A1 at Tempsford to continue their journey.
Phase 3: A1 Wyboston Interchange, southbound exit slip road on Tuesday, October 6 for one night.
Southbound traffic wanting to leave the A1 at the Wyboston Interchange will continue to the Black Cat Roundabout and will return on the A1 northbound to the A1/A428 Wyboston interchange.
Phase 4: A1 Buckden Roundabout, southbound to A1/B645 St Neots interchange from Monday October 12 to Friday, November 20 for seven weeks.
Traffic will be diverted northbound on the A1 to join the A14 eastbound at junction 22 via Brampton Hut and the A1 southbound. At junction 23, traffic will then join the A1198 southbound, then the A428 westbound to re-join the A1 southbound at Wyboston Interchange.
Residents who require access directly from the A1 southbound carriageway will be escorted through the works.
There are also roadworks that will be carried out on the A14 between Cambridge to Huntingdon.
Highways England are currently carrying out finishing works for which they need to close lanes or carriageways on the A1, A14 and some local roads at times, usually overnight between 8pm and 6am, unless otherwise stated.
A clearly signed diversion route will always be in place for closures.
For this week, the planned closures are: Monday, September 21 to Saturday, September 26 for six nights at Hinchingbrooke Park Road loop.
