A city centre road is due to close to allow for a mobile crane to be brought in ahead of redevelopment works.
Carrington Street near Nottingham train station will be closed from 1am to 4am on Sunday, February 23 and then again on Sunday, March 1.
The closure, announced by Nottingham City Council, is due to redevelopment works being carried out by a private developer, Office Innovations on the historic City Building.
The iconic building is on a key route between the Nottingham train station and the city and is set to become offices after it was sold to developers.
This 19th century block of shops, office space, studios and workshops - which used to be home to the Redmayne & Todd sports shop - was put on the market with an asking price of up to £4m.
The building currently houses a number of retail units on the ground floor including Caffé Nero on the Canal Street corner.
A spokesman for the city council said: "A mobile crane is required on Carrington Street to facilitate works on the roof of the building.
"The carriageway closure on Carrington Street will be from its junction with the Canal Street to its junction with Station Street."
An alternative route for traffic has been put in place from Castle Boulevard to Wilford Street, then Wilford Road, Waterway Street West and Sheriffs Way.
The work is expected to cause minor delays.
