Overnight improvement works on a busy road have been pushed back due to a football match.
National Highways is working on the A12 southbound carriageway between junction 33 for the Copdock Interchange, near Ipswich, and junction 32b and 32a, near Capel St Mary.
Works began on Monday and run every night up to Friday between 21:00 and 05:00 GMT.
However as Ipswich Town take on Watford at home at Portman Road, Simon Amor at National Highways said the closure later would begin at 22:30.
"We are aware traffic will be busy in light of the Ipswich Town match and have delayed full closure of the road to 22:30," he said.
