Castle Road will be closed northbound from Castle Roundabout from Monday 5th of February, with a long diversion route to be put in place.
The official diversion for motorists is to travel out on London Road via Cholderton and Amesbury and then head back into Salisbury.
The closure is expected to cause extra traffic on Ashely Road, St Marks Avenue and London Road with local drivers using residential and backroads to avoid the full diversion.
Buses will also be diverted, with Salisbury Reds confirming the alternative route their drivers will take to avoid the closure.
The road is being closed for approximately two weeks for SGN gas works with work expected to complete by 17th February. The southbound section of Castle Road will remain open as usual.
During this time, all buses that normally use Castle Road will be subject to diversions.
