Work on overhead power lines on the A47 south of Norwich is causing major traffic delays this morning.

From today, a contraflow is in operation on the eastbound carrageway of the A47 Southern Bypass, between the A11 and the A140.

Both eastbound and westbound traffic is travelling on the eastbound carriageway while the westbound lane is closed to allow engineers to replace wires on the overhead power line.

The work is due to last until August 5.
