A40 Northern By-Pass (Oxford) Proposed Speed Limits & Traffic Restrictions

Oxfordshire County Council proposes to introduce a number of measures aimed at improving the flow of traffic to reduce journey times, and help to improve road safety along the stretch of the A40 Northern By-pass approaching the Wolvercote roundabout. The proposals are part of the wider western A40 Corridor improvement project, and specifically the changes comprise of the following proposals:

  • extend the existing 30mph speed limit west of the Wolvercote roundabout, westwards to beyond the A34 flyover bridge,
  • thereafter introduce a 40mph speed limit for 700 metres, replacing parts of the existing 40mph & 60mph national speed limit,
  • Introduce 7.5 tonne weight restrictions on the proposed 4 new access roads either side of the A40:
    • North side, approximately 300 metres west of Wolvercote roundabout, and 200 metres east of the A34 flyover; and
    • South side, approximately 270 metres west of Wolvercote roundabout, and 200 metres east of the A34 flyover.
  • To prohibit U-Turns on the A40, 200 metres east of the A34 Flyover at the new service side roads, and
  • A new Bus only lane* introduced on the A40 nearside lane (Oxford-bound) from near the A34 flyover to approaching Wolvercote roundabout.

* note: standard exemptions will apply (i.e. emergency vehicles & cycles), however it is planned that Taxis & Private Hire Vehicles will not be permitted to utilise the bus lane.

Objections to the proposals and other representations, specifying the grounds on which they are made, may be sent in by completing the online questionnaire, via email or in writing (quoting ref: CM.12.6.320) to the address below by 11 September 2020. The Council will consider objections and representations received in response and they may be disseminated widely for these purposes and made available to the public.

Any unresolved objections will be reported to the Council’s Cabinet meeting later in 2020. The papers for the meeting will be available on the County Council’s website about a week before the meeting.
