Trial measures are to be implemented along a busy King’s Lynn road in a bid to tackle traffic congestion.
West Norfolk Borough and Norfolk County councils have come up with a joint scheme for the A148 London Road.
It will see the two-lane section out of town being extended beyond the Valingers Road junction and the creation of a right-turn lane into Valingers Road.
The trial will also see the traffic lights at Valingers Road taken out of operation but the pedestrian crossing further along London Road near the junction with Windsor Road will remain.
While the two out of town lanes will be extended, the lanes coming into town will be reduced to one lane south of the junction.
Martin Wilby, chairman of the county’s environment, development and transport committee, said: “We’ve listened to what the borough council and local people have told us about their frustrations with the congestion on London Road.
“These relatively small changes will be quick to make and could really help to tackle this problem, leading to reduced journey times and making it easier for local people and visitors to get around the town.”
West Norfolk Council leader Brian Long said: “We have agreed to this trial as it could prove to be a very effective quick fix.
“Our main concern is that we make it easier for people to get around the town whether they are visiting or working here.
“The effects of this change will be monitored and the results fed into the overall transport study.”
Work is set to begin on Monday for five days to re-mark the carriageway. It is due to take place in the evenings to minimise disruption.
The trial is expected to start once this work has been completed.
A county council spokesman said the scheme is expected to last several months to enable officials to gauge its success.
The county and borough councils are currently carrying out a £300,000 transport study to analyse current and future transport issues in the town which will lead to the creation of a transport strategy for Lynn.
The study is expected to be completed by the end of the year and the impact of the trial changes at London Road will be assessed as part of it.
