National Highways has announced temporary speed limits and layby closures on the A14 in Cambridgeshire as a four-month maintenance programme gets underway. The scheme, which begins on Monday, August 24, 2026, affects the stretch between Junction 33 Milton Interchange and Junction 35 Stow-cum-Quy Interchange, near Cambridge, according to a Public Notice Portal notice also published in Cambridge News.
What the works involve
The programme includes carriageway resurfacing, waterproofing, replacement of bridge expansion joints, installation of new communications ducting and drainage, sealing of concrete cracks, renewal of safety barriers, and refreshing road markings and studs. These works are designed to improve the safety and longevity of the road surface and infrastructure.
To maintain traffic flow while crews are working, narrow lanes will be in operation in certain sections. Restrictions will only be enforced when signs are displayed, ensuring minimal disruption when work is not taking place.
Key restrictions
Temporary mandatory speed limits will be in place 24 hours daily, used in conjunction with narrow lanes where required. The specific limits are:
- 50mph eastbound from a point 150 metres east of the centre of Junction 33 Milton Interchange eastern overbridge for 950 metres.
- 50mph westbound from the Junction 35 Stow-cum-Quy Interchange entry slip road for 1500 metres.
- 50mph on the eastbound entry slip road at Junction 33 Milton Interchange.
- 40mph eastbound from 1000 metres east of the Junction 33 eastern overbridge to the exit slip road at Junction 34 Fen Ditton Interchange.
- 40mph westbound from 1500 metres west of the Junction 35 entry slip road to 300 metres west of the westbound entry slip road at Junction 34.
All laybys adjacent to the eastbound and westbound carriageways between Junction 33 and Junction 35 will be closed 24 hours daily. Mandatory speed limits do not apply to emergency service or special force vehicles, and closures do not apply to emergency service, traffic officer, works or winter maintenance vehicles. Diversion routes will be clearly signed when closures are in place.
Timeline and duration
The order takes effect on Monday, August 24, 2026, and remains in force until the works are completed or for a maximum of 18 months, whichever is earlier. National Highways expects the programme to last approximately four months, with restrictions operating as required and only when traffic signs indicate.
Impact on drivers
Motorists should look for live signage on approach, observe the temporary limits, and plan journeys accordingly. The restrictions are necessary to protect the workforce and ensure safe passage through the roadworks. Emergency services are exempt from the speed limits, but other drivers must adhere to the reduced speeds to avoid penalties.
