A section of a main road into Northampton will be closed for the next four weeks due to roadworks.
A diversion has been put in place for motorists as Harlestone Road, between the Quarry Road and Whites Lane junction, is currently closed for sewer works.
Buses are being diverted onto New Sandy Lane, left into Weggs Farm Road, left into Sandy Lane, right into Port Road, left into Quarry Road and right back onto Harlestone Road.
A spokesman for Stagecoach said: “All bus stops will still be served but buses may experience slight delays due to the diversion.
“We apologise for any inconvenience caused.”
