Heavy traffic caused delays across Norwich on Thursday morning as Sweet Briar Road remained closed.
Drivers reported experiencing "gridlocked traffic" with cars at a standstill in Magdalen Street.
Elsewhere in the city, there were also heavy delays in St Crispins Road, Yarmouth Road, Martineau Lane, Newmarket Road and Dereham Road.
It comes after busy city route Sweet Briar Road was shut after a pipe burst and an embankment beneath the road fell through.
While work is ongoing for a number of weeks to fix the issue, a diversion is in place via Dereham Road, Barn Road and Aylsham Road, with delays to be expected.
