Major work to widen part of the A1077 to help reduce accidents and improve safety at the Ferry Road West junction in Scunthorpe starts on Tuesday March 29 for 13 weeks.
Temporary traffic lights will be in operation to control the traffic and there will be a 30mph speed limit in operation.
At some point during the work, traffic will not be able to turn right out of the B1216 onto the A1077. Instead traffic will be directed left onto the nearby Skippingdale roundabout.
The work involves widening the road, constructing new traffic islands and installing new traffic signals, plus resurfacing the carriageway and its approaches to the junction.
The council will also upgrade the street lights and a new 50mph speed limit will be introduced on the A1077 from the junction with Luneburg Way to a point approximately 300m south west of the B1216 Ferry Road and the B1216 from Neap House roundabout to the A1077.
The council will monitor traffic to ensure disruption is kept to the minimum.
The cost of the work is approximately £400,000.
Councillor Neil Poole, cabinet member for Neighbourhoods at North Lincolnshire Council, said: “This is a major investment that will make the junction safer, reduce accidents and improve traffic flow through the junctions.
“There were ten personal injury accidents at this junction in the last four years. Seven of those were at the Neap House and Ferry Road West junctions. The work is essential and will help improve safety at this junction.”
