The bypass will be closed from September 7, with the restrictions in place throughout the planned works. Southern Water is carrying out utility repair and maintenance work, with Hampshire County Council approving the closure. The closure forms part of ongoing maintenance to Southern Water's infrastructure in the area. Motorists are being advised to plan ahead and allow extra time for their journeys, particularly during peak travel periods. Drivers are being asked to instead travel on Main Road and join the Marchwood Bypass at the Cocklydown Lane and Knellers Lane Roundabout.
