The project to improve express bus services currently remains at feasibility stage. An option including the extension of the northbound off – slip road, with bus priority, has not met Highways England approval.
Alternative options for improvement such as an additional bus lane eastbound on the A423 Southern Bypass Road between Hinksey Hill Interchange and the Kennington Roundabout are currently under investigation.
Why we are doing this project?
This project provides Stage 1 of the Oxfordshire Science Transit Network, as identified in the county council’s City Deal commitment.
Stage 1 of Science Transit focuses on Hinksey Hill interchange, with the aim of unlocking capacity, particularly for express bus services. This will enable a significantly increased service pattern (in particular services from Harwell and Didcot / Milton Park), increasing public transport use and taking traffic pressure off a congested section of the A34.
The key benefits of the scheme include:
- reduction in total traffic delay by 65% in the am peak hour (more than 200 passenger car unit hours) and 22% in the pm peak hour (over 25pcu hours)
- business users and transport providers. Highway travel time savings £20.8 million highway vehicle operating costs £7.7 million
- commuting and other users. Highway travel time savings £8.4 million highway vehicle operating costs £2.7 million.
Work is currently being undertaken through the feasibility stage of the project to identify a preferred option.
This page will be updated with further details of the preferred option once confirmed.
