Part of Oxford's eastern bypass is to be closed to night-time traffic this week while roadworks are carried out. The road will be closed from 2100 GMT to 0500 GMT every day until Friday morning.
The stretch affected is between Horspath Driftway and the Headington A40 roundabout.
Oxfordshire County Council said the closure of the carriageway was necessary to remove scaffolding from the old road bridge.
