Here’s the official notice: I have digital versions of the maps, so contact me if you want a copy.
Subject: FW: T2689 A420 Cumnor Bypass CLOSURE Tues 7th April 2015 – 8 to 9 weeks
Temporary Traffic Regulation Order – S14 Road Traffic Regulation Act 1984
Temporary Road Closure – A420 Cumnor Bypass- between the A34 Botley intersection and the B4017 Wootton turn (Cumnor interchange)
In the interests of public safety it will be necessary for Oxfordshire County Council to close a short section of the road above to facilitate the rebuilding of a failed embankment and resurfacing works.
A Temporary Traffic Regulation Order (TTRO) is being made to implement the temporary closure.
In two phases for approximately 8 weeks – when appropriate traffic signs indicate:
1) Westbound will be closed for the majority of the time
2) Eastbound side will be closed – 3 nights (8pm to 6am)
The attached diversion will operate, initially, for the westbound traffic during the first phase and then the eastbound traffic during the second phase.
The maximum duration of a TTRO on a road is 18 months, or until completion of the works, whichever is the earlier.
Notice of intention to make the Order will be published in the Oxford Times.
Access will be maintained for emergency service vehicles and also overnight access for those frontages within the closure area, subject to the progress of the works. Please note that access routes will depend on exactly where the works vehicles are at any time and may need to be negotiated with the gang on site as necessary.
Further information regarding the works may be obtained by contacting John Beaumont, OCC Highways & Transport on 0845 310 11 11.
