A423 Kennington improvements programme – site investigation work and footway, cycleway, and traffic diversions
Information received from Oxfordshire County Council:
We are planning to improve the Kennington stretch of the A423, by replacing the existing rail bridge structure and prioritising space for cycling, walking and public transport. We are writing to update you on some site investigations taking place in the area and the closures and diversions you can expect.
To help us finalise the design, we need to investigate the condition of the ground, while also locating any utility cables and water mains that may be beneath the surface. The investigations will start on Tuesday 28 May 2024 and will be completed by Wednesday 12 June 2024, with work happening both during the day and at night. To allow our teams to complete the work safely, the following locations will have temporary traffic management in place, as explained below.
The junction of the A423 Southern Bypass and Old Abingdon Road (eastbound) (next to Redbridge Hollow)
24-hour closure – 28 to 31 May 2024:
- The junction will be completely closed for 24 hours each day from 9.30am on Tuesday 28 May until 11.59pm on Friday 31 May.
- Our working hours during this time will be between 7am and 6pm.
Overnight closures – 31 May to 12 June 2024:
- The junction will be closed overnight from 9pm to 5am, from Friday 31 May to Wednesday 12 June. We will not be working on Sunday 2 June, Thursday 6 June and Sunday 9 June, and the junction will be open on these dates.
- During the overnight closures, lane one of the A423 eastbound will also be closed between the A34 southbound exit slip road (Hinksey Hill interchange) and the Old Abingdon Road junction.
24-hour closure – 10 to 12 June 2024:
- The junction will be completely closed for 24 hours each day from 9pm on Monday 10 June until 5am on Wednesday 12 June.
- Our working hours during this time will be between 7am and 6pm.
Diversion routes
During the closure of the Old Abingdon Road junction, the following signed diversion routes will be in place:
- Old Abingdon Road junction diversion- travel eastbound along the A423 Southern Bypass Road, before joining the A4144 northbound at the Kennington roundabout, and accessing Old Abingdon Road just after the Travelodge.
- The same diversion applies in the reverse direction.
Footway and cycleway diversion
The footway and cycling route from the A423 Southern Bypass Road to the Old Abingdon Road will be closed from 9am Tuesday 28 May until 6am on Wednesday 12 June. During this time, the following signed temporary diversion routes will be in place:
- From Redbridge Hollow, go to Kennington Road, continue under the road bridge and turn left to take the slip road. Turning left at the top continue on the south side of the A423 to the Hinksey Hill interchange, go round the interchange to re-join the route.
- The same diversion applies in the reverse direction.
We will try to reduce noise as much as possible and aim to carry out the noisiest work during the earliest part of the overnight period. The working area needs to be lit with temporary lighting for safety when we work overnight. We apologise in advance for any disturbance caused.
We will also need to undertake several ecology surveys in the area soon, and we will provide more information when it is available.
