It is near the John Radcliffe Hospital but traffic appears to be coping well with some minor delays at the moment.

Oxon Travel says engineers are working to resolve the issue.

However, it warned motorists to "approach with caution".

This comes after traffic signals on the M40 junction nine Wendlebury roundabout cut out.
