A MASSIVE £1 million roadworks project on the A40 is set to cause weeks of delays from Monday.

The 'significant' maintenance project will include resurfacing of the westbound carriageway between Thornhill Park and Ride and Ridgeway Road, drainage repairs, duct installation and new kerb installation.

The work is expected to last up to four weeks and, although there will be disruption during this period, it is hoped that the new surface will not need further structural maintenance for many years to come.

Oxfordshire County Council said it has designed traffic management for the project to minimise impact on residents, businesses and all road users affected by these works.

The authority said this will include lane closures, speed limit reductions and night-time working.

Delays are likely throughout the works and commuters are being asked to review their daily route, mode of transport and time of travel and where possible consider alternatives.

The authority said the aim of the works was to 'improve the road surface of an extremely busy route into Oxford... accommodating local bus routes and coaches to and from London... meaning that no major road reconstruction will be required on this stretch of road for many years to come'.
