We hosted a digital exhibition of our plans from Monday 26 September to Sunday 23 October.
The exhibition included a feedback form, the results of which will inform our planning submission in November and how we keep people updated about these improvements.
The feedback form is now closed, but the digital exhibition can still be viewed by going to https://letstalk.oxfordshire.gov.uk/a423-kennington-improvements
We also hosted four walk-in face-to-face sessions where the same information was available and people could ask questions. The events took place at St Luke's Church on Wednesday 28 September and Kennington Village Hall on Thursday 29 September.
About the improvements
The A423 Kennington improvement programme includes:
- the replacement of Kennington Rail Bridge.
- a shared path for walking and cycling.
- a new eastbound bus lane – also for use by vehicles travelling to Redbridge Park and Ride.
- increased capacity of the Hinksey streams for flood alleviation.

Why we are investing here
We are investing across the county to provide a modern, sustainable travel network to enable people to rely less on their cars. This means putting better bus, as well as cycling and walking infrastructure at the centre of our major projects.
Kennington Rail bridge is in poor condition and needs to be replaced. Reconstruction of the bridge will ensure safety for all users as well as the opportunity to prioritise road space for bus, walking and cycling.

This may be subject to change, due to the complexities of the work involved.
What you can expect
Kennington Rail Bridge will remain open until we start building works. We will rebuild the bridge half at a time so that traffic can flow over the remaining half of the bridge.
Temporary widening and contraflow traffic management will also be in place (more details will be available closer to construction).
Phase 1 - Safeguarding work
The bridge has been propped at its piers and its load-carrying capacity of the bridge will be increased for work to be carried out safely.
Phase 2 – Reconstruction
The bridge reconstruction work will involve several elements:
A423 Eastbound Bus Lane
We are proposing to widen the A423 eastbound from Hinksey Hill to introduce an additional all-traffic lane for left-turning vehicles from the A34 Hinksey Hill Roundabout to Old Abingdon Road, creating a three-lane carriageway.
The new lane from Old Abingdon Road to Redbridge Park & Ride will be for exclusive use by buses and vehicles using the Park and Ride. The approach to Kennington Roundabout will become four lanes as a result of the additional bus/ Park and Ride traffic lane.
Walking and cycling facilities
We will create a shared-use path to the north of the A423 by upgrading the existing footway between Hinksey Hill and Old Abingdon Road.
Oxford Flood Alleviation Scheme (OFAS)
The work on the Kennington Rail bridge forms an integral part of OFAS.
Combining the bridge replacement works with the flood alleviation scheme requirements will minimise disruption on the A423 and maximise value for money.
The EA submitted its planning application in March 2022. For more information on OFAS, visit the EA FAQ page on their scheme.
From 24 January to 10 February 2023 trial holes are being dug to help plan the diversion of water mains as part of the A423 improvements.
Work will take place at night with the following lane closures:
- 24 to 30 January: lane 1 (inside lane) eastbound closure between Hinksey Hill interchange and Kennington roundabout
- 31 January to 3 February: designated left lane closure from A423 Southern Bypass Road eastbound to A4144 Abingdon Road
- 6 February to 10 February: lane 2 (outside lane) eastbound and westbound closures between Hinksey Hill interchange and Kennington roundabout.
How it is being funded
The scheme is being financed through multiple sources including the county council, Oxfordshire Local Enterprise Partnership and OFAS.
