The first section of Norwich's £178 million Northern Distributor Road will be opened tomorrow morning.
The section linking the A1067 Fakenham Road to the A140 Cromer Road is opening 4 months ahead of schedule.
The opening of the 6 km of dual carriageway will happen in the early hours of Saturday.
This section of the route includes roundabouts at Fir Covert Road, Reepham Road and Drayton Lane, and signs will be going up to warn drivers to expect traffic to be on the NDR.
For eastbound traffic (heading towards the A140 Cromer Road), the carriageway will be reduced to a single lane on the final section from Drayton Lane to the A140 Cromer Road.
This is because it will all have to leave at the slip road to join the A140. Otherwise, the newly-opened road will be available as a normal part of the road network, with the national speed limit (70mph) on the dual carriageway.
