Chorley Hall Lane will be closed from from the junction with Blackshaw Lane to the junction with Carlisle Street on Monday, 25th September.
The closure is to enable an investigation to be carried out into the bridge structure and road surface, in preparation for the footpath widening and introduction of a one-way system between Greenlands Walk and Carlisle Street.
Councillor Craig Browne said "The attached diagrams show the proposed method of extending the footpath, permanently closing off a section of footpath using polymer lane separators with reflective strips bolted into the road surface.
"There will be a formal public consultation on this scheme, later in the year."
Pedestrian access to any premises situated within the temporary closure will be maintained at all times and access for emergency vehicles and residents will be maintained where possible.
