Preparations for the start of a redevelopment scheme in Leicester costing £19m are under way.
The improvements will see new paving, trees and street furniture installed on Gallowtree Gate.
A site office is to be erected by the Clock Tower in the city centre and temporary hoardings will cordon off an area for construction workers to use.
Wooden sheeting will also be placed around the base of the Clock Tower to protect it before the work begins.
As part of the scheme, work will also begin on Halford Street, including the re-building of footpaths and installing loading and disabled parking bays.
Traffic in the area will face diversions while the work is completed.
A council spokeswoman said: "In order for the improvements on Halford Street to take place, the traffic flow on Granby Street will have to change to accommodate diverted traffic.
"Traffic flow on Granby Street, between Bishop Street and Belvoir Street will be reversed so that traffic can come down Bishop Street and turn right into Granby Street, then Rutland Street or Belvoir Street."
