Disruption is expected to bus services as roadworks are set to be carried out on a key route through the city.
First Bus has warned that its Orange, Pink, Turquoise and Purple lines will be impacted by upcoming works in Magdalen Street.
The road will be closed from its junction with Colegate for 30m northwards from February 12 to 14.
The closure will be in place between 7pm and 7am each night while works are carried out by Anglian Water.
This closure was initially planned to be in place for three full days.

A spokeswoman for First Norwich said: "After being notified of this plan in December we raised concerns about the level of disruption that daytime closures would cause and worked with Norfolk County Council to secure the least disruptive option for our customers."
The Pink Line from the city will run its normal route to Tombland, left at the Maids Head into Palace Street, then straight over the ring road roundabout into Bull Close Road, and will operate the same route towards Norwich.
The Yellow and Orange lines from the city will operate the normal route to Tombland, left at the Maids Head into Palace Street, then ring road, Pitt Street, with Orange Line services into Waterloo Road to resume normal route.
Yellow and Purple Line services will continue straight to join the normal route.
