The Broad Street Bridge Preventive Maintenance Project begins this week, which will affect traffic along Broad between Exchange Street and South Avenue.
The bridge will remain open for two-way traffic, with one lane in each direction for the duration of the project.
Parking on the bridge and Broad St. between Exchange St. and South Ave. will be prohibited during the project.
Most of the work is expected to be completed by the end of this year, but Rochester officials say some work may extend into the summer of 2017.
