There is going to be major disruption to road journeys along the A420 when work starts on a maintenance project that will last for seven weeks starting on 23 July.
Oxfordshire County Council is investing £3.5million on work that will improve the standard of the road surface and maintain the drainage and safety barriers on the Shrivenham by-pass four miles east of Swindon.
During the closure of the A420 between Watchfield Roundabout and Lower Bourton Junction alternative routes are:
HGVs over 7.5 tons via A34/M4
All type local East-West (Oxford-Swindon) traffic via A417 East – A4185 South – A34 – M4
All type West-East (Swindon-Oxford) traffic via M4 – A34
Non motorway traffic will be advised to find alternative routes.
All road users will be affected by this work and severe delays are to be expected. Everyone is being asked to review their travel plans and where possible consider alternative routes.
Local traffic will be diverted through Shrivenham High Street which will have a 20mph speed restriction temporarily imposed from Townsend Road. Oxford bound local traffic will be directed onto Faringdon Road. A 30mph speed restriction will be temporarily imposed for the full length of Faringdon Road.
Swindon bound local traffic will be diverted via Majors Road and Longcot Road and a 40mph speed restriction temporarily imposed. Please find the attached diversion route plans.
All the bus services (including Route 66) will be maintained throughout the duration.
Local access and heavy vehicles
Access will be maintained to properties and businesses within the closed section of the A420. Measures will be in placed to prevent all through traffic above 7.5T using unsuitable local roads.
Deliveries to shops and businesses in Watchfield and Shrivenham and the surrounding local area will require the HGV drivers to produce delivery documentation evidence such as a delivery note to the marshals/Trading Standards Officers at each end of the bypass.
Shops and businesses are encouraged to arrange for deliveries to be outside peak hours if at all possible. Businesses will remain accessible and open as usual.
The project has a web page which will be updated on a regular basis
The county council’s Travel Choices webpages provide live travel information, a journey planner and information alternative modes of transport and other major transport schemes.
