Part of Lancaster’s one-way system is to be closed from tomorrow, Monday, as United Utilities begin the final stage of work on the city’s sewer system.
The £18m project is due to end in November, with the final phase due to start on Monday.
The junction where North Road meets the A6 Rosemary Lane will close for up to two months, and traffic heading into Lancaster from Morecambe and traffic along Caton Road will be diverted along Bulk Road and St Leonardgate.
Some bus services will be relocated from the bus station to Dalton Square.
Dawn Harrington, project manager, said: “We’re delighted to be moving into the final phase of our work.
“Unfortunately it will require a few temporary changes to some of the traffic routes around the city centre.
“We know the changes we need to put in place will impact people getting in and around the city.
“We have been planning this work for a long time to make sure we can keep the impact to an absolute minimum.
“But I would urge everyone from motorists, commuters, cyclists and pedestrians to pay extra attention during the changes and give themselves a bit more time.
“All the changes will be clearly signposted.”
When this work is finished it will help the system cope better during heavy periods of rainfall, protecting the River Lune.
