Information received from Oxfordshire County Council 24 March 2022:
Dear resident or business owner,
A423 Kennington Improvements Programme
I am getting in touch to let you know about works to improve the A423 Southern Bypass Road, between Hinksey Hill interchange and Kennington roundabout. These works are part of the A423 Kennington improvements programme, which will deliver:
a. A new eastbound lane dedicated for bus and Park and Ride traffic from Old Abingdon Road to Redbridge Park and Ride
b. An upgrade to existing foot and cycleways
c. The replacement of Kennington railway bridge
d. Improvements to the Hinksey streams as an enabler to the Oxford Flood Alleviation Scheme
From Monday 28 March until the end of April 2022, our principal contractor and their specialist subcontractor will be undertaking geotechnical investigation works along the A423 Southern Bypass Road, on both sides of the carriageway between Hinksey Hill Interchange and Kennington roundabout. These works are necessary to complete the design of the scheme.
The works will be undertaken during both day and night shifts, with most of the works being undertaken at night. Day shifts will be typically carried out between 07:30 and 17:30 and night shifts will be typically carried out between 22:00 and 05:00.
Please see the map overleaf which shows the locations of these works, comprising windowless sampling with rotary coring follow on (drilling into the ground and extracting samples of soil), trial trenches, windowless sampling (drilling or boring into the ground to assess its condition) and hand dug trial pits.
We need to use lane closures, diversions and temporary traffic signals to manage this work safely. Some minor delays can be expected, but we will try to minimise disruption and help you to avoid delays where possible. Please consider walking, cycling or using public transport where possible during this time. You can stay informed by signing up for our travel bulletin and following our social media feeds.
You can expect the following night-time closures and diversions:
• A423 east bound lane 1 closure from Hinksey Hill interchange to Kennington roundabout
• A423 west bound lane 1 closure from Kennington roundabout to Hinksey Hill roundabout
• Old Abingdon Road on/off slip road closure and diversion
• Kennington Road on/off slip road closure and diversion
We will also be carrying out some work from 07:30 to 17:30, on Wednesday 30 and Thursday 31 March.
You can expect:
• Two-way temporary traffic signals on Kennington Rd
• Pedestrian diversions
There will be no closures or diversions from Thursday 14 to Monday 18 April, to prevent disruption over the Easter Bank Holiday weekend.
