Bridge Replacement Project Part of $17 Million Safety Improvement Project in Area Around Exit 43 (Manchester – Route 21)
State Route 21 Bridge Over NYS Thruway in Manchester Will Be Shut Down to Traffic While Project is Completed

The New York State Thruway Authority today announced the replacement of the State Route 21 Bridge over the NYS Thruway in Ontario County will begin Wednesday, August 1, 2018. The bridge replacement is part of a $17 million safety improvement project in the area of exit 43 (Manchester – Route 21) which also includes the replacement of the exit 43 ramp bridge, culvert repair, and pavement rehabilitation.

Originally built in 1952, the State Route 21 Bridge carries approximately 9,000 vehicles per day over the Thruway (I-90) in the Town of Manchester. The bridge will be replaced with a two span, 236-foot long bridge that will have an anticipated lifespan of at least 75 years. The new bridge will feature safety improvements, including increased height clearance for vehicular traffic on I-90, wider travel lanes, improved approach pavement and increased shoulder widths along Route 21.

To accommodate the bridge replacement, the bridge is scheduled to be closed to all traffic during construction through the middle of November. During the scheduled closure, all passenger vehicles will be detoured via Outlet Road – County Road 7 – and State Route 31. Trucks will be detoured via State Route 96 – County Road 7 – and State Route 31.

Variable Message Signs are already illuminated and will advise motorists of the bridge closure and detours. The work and closure is weather dependent and subject to change.
