Introduction 1.1 Background Witney and Carterton are the two largest towns within West Oxfordshire. They have both seen considerable growth over the last 30 years: Witney grew from 15,000 inhabitants to 28,000 between 1981 and 2011 while Carterton grew from 11,000 to 16,000. This has been accompanied by a growth in trips made by residents of the two towns. This is particularly the case for trips to and from Oxford, which acts as a major attractor for employment commuting as well as shopping and leisure activities trips. Growth in Witney and Carterton is expected to continue to grow in the future; the Draft Local Plan (October 2012) included provision for 5,500 houses in West Oxfordshire up to 2029 with “the majority of housing to be built at Witney and Carterton”; the Oxfordshire Strategic Housing Market Assessment (March 2014) gave a Housing Need per Year (2011-31) for West Oxfordshire of 635-685 which would substantially increase the required provision. The A40 between Witney and Oxford is a single carriageway Primary Route. To the west of the Witney - Oxford section there is the dual carriageway Witney Bypass beyond which the road is mainly single carriageway to Cheltenham. To the east of the Witney - Oxford section the road has an urban single carriageway section through the northern suburbs of Oxford after which it forms the dual carriageway Northern Bypass section of the Oxford Ring Road and extends on to meet the M40 at Wendlebury. The section of A40 from Wolvercote to Eynsham was constructed in the 1930s as the Oxford Northern Bypass. A Master Plan for the upgrading of the A40 between Oxford and Cheltenham to dual carriageway standard was developed in the 1970s; this included the Witney Bypass built in the mid-1970s, the Witney-Cassington Dualling scheme and the Oxford Northern Bypass (“tin hat”) schemes. The latter two schemes were designed, and in the case of the Witney-Cassington Dualling scheme Orders were published and approved, but they were dropped from the National Trunk Road Improvement Programme in the mid- 1990s when the size of this programme was drastically reduced. 1. Introduction 1 A40 Oxford – Witney Corridor Strategy - Baseline Statement The A40 route was “de-trunked” in 2002 and the route passed to Oxfordshire County Council control. A scheme to build a bus lane along the A40 was put forward for government funding support in 2001 but was unsuccessful. A 3-stage strategy was developed in 2002 for improving transport links between Carterton, Witney and Oxford and the first stage of this formed the basis of the “Northern Gateway” proposals included in the Access to Oxford package. However government funding for developing this package was withdrawn in 2011. Oxford and Witney were previously connected by a single track railway which extended to Brize Norton/Bampton, Carterton (Black Bourton) and Fairford. This was closed to passenger traffic in 1962 and to freight services in 1970. 1.2 Scope of Report The purpose of this report is to: Identify and analyse the travel problems, between Oxford and Witney Carterton both at the current time and into the future Put forward a set of objectives against which alternative schemes can be judged Identify possible schemes or packages of schemes that might remedy the identified problems Assess, at a broad level, the potential of the identified schemes to alleviate or resolve the problems It is not the purpose of this report to select a preferred solution to the identified problems nor to detail the business case for any schemes. It will, though, seek to identify what additional work needs to be carried out to allow such decisions to be made. 1. Introduction 2 A40 Oxford – Witney Corridor Strategy - Baseline Statement 2. Capacity and Capability of Route 2.1 Context The A40 between Witney and Oxford is a single carriageway Principal Road. It is signed as the Primary Route between Oxford and Cheltenham; it also is signed as the advisory route for lorry traffic between Oxford and Evesham to encourage these vehicles to avoid the Air Quality Management Area in Chipping Norton. It forms the most direct transport link between Oxford and Witney although there are less suitable alternatives using A4095/A44 andB4449/ B4044; the A4095 also forms an informal route for bypassing the A40 and Oxford for longer distance traffic. Currently nearly all public transport connections also use the A40, at least on the section between Witney and Eynsham. Some vehicle traffic between Carterton and Oxford travels via Bampton to the A420 to avoid the A40. To the west of the Witney -Oxford section there is the dual carriageway Witney Bypass beyond which the road is predominantly single carriageway to Cheltenham. To the east of the Witney - Oxford section the road has an urban single carriageway section through 3. Future Route Requirements 3 A40 Oxford – Witney Corridor Strategy - Baseline Statement the northern suburbs of Oxford after which it forms the dual carriageway Northern Bypass section of the Oxford Ring Road and extends to meet the M40 east of Wheatley. 2.2 Route description and characteristics The A40 is a single carriageway for its entire length between Wolvercote roundabout and the eastern end of the Witney Bypass. The section between Wolvercote roundabout and the A34 flyover (0.7 km) has wide verges, although these are partly utilised by shared footways/cycleways on either side of the road. Immediately west of Wolvercote roundabout there is the entrance to a petrol service station area and showroom on the northern side. The roadway passes under one span of the A34 overpass, although the footway on the northern verge uses an adjacent span. Immediately to the west of the A34 there are a series of bridges over the Oxford Canal, Oxford-Banbury/Worcester railway and Duke’s Cut (a canal link connecting the Oxford Canal and River Thames) where the verge is limited to that necessary for the provision of the footway/cycleway (0.7 km). To the west of these bridges the road makes a slight bend and then is straight with the wide verges restored and the highway is fringed with mature trees (2.3 km). There are limited accesses off the road until it approaches Cassington where there is a layby on the southern side of the road, separated from the carriageway, followed by the entry into the Cassington Gravel Works. These works have separate junctions on the north and south sides of the road with vehicles crossing the line of the A40 using a private haul road on the track of the old Oxford-Witney railway line. As the A40 crosses this line on a bridge the verge is again restricted to solely providing a footway on each side of the road. South of the road along this section of the road is the Oxford Meadows Special Area of Conservation which is noted for lowland hay meadows including vegetation communities that are “perhaps unique in the world in reflecting the influence of long- term grazing and hay-cutting. The site has benefited from the survival of traditional 3.

This allows access onto the A40 but entry into the side-road is prohibited. There is a field access point opposite this on the southern verge. The road is straight with wide verges and only a couple of field accesses on the southern side west from this point until the traffic signal controlled junction with Cassington Lane (0.75 km). There are two sets of traffic signals at this location with the northern and southern junctions skewed by approximately 50 metres. The roadway widens at this point with two eastbound lanes on the approaches to the traffic lights and a bus stop 1 http://jncc.defra.gov.uk/protectedsites/sacselection/sac.asp?EUCode=UK0012845 3. Future Route Requirements 5 A40 Oxford – Witney Corridor Strategy - Baseline Statement layby and a private means of access on the southern side. To the west of the lights there is a bus stop on the northern verge. To the west of Cassington Lane the verge becomes more restricted with works buildings on the southern side and a restricted width bridge over the River Glyme (0.3 km). West of this the road is straight with relatively wide verges until the Eynsham Roundabout (1km); on this section there are field accesses on both sides of the road and a service area is located on the southern side of the road at the approaches to the roundabout with localised widening of the road at this point to 3 lanes. Eynsham Roundabout was originally built in the 1980s as part of the Eynsham Bypass but was redesigned in the mid-1990s to increase its capacity.
