GENESEO – The intersection of Route 63 and Court Street will close to all traffic next month as part of the ongoing $8.7 million project to replace the bridge over the Genesee River and install a roundabout, the state Department of Transportation has announced.

Route 63 will be closed beginning Aug. 13 for about eight days to incorporate the new bridge, which was built parallel to the existing truss bridge, into the roadway. A detour will be in place along Route 63 through Aug. 21 directing traffic on Route 63 to use route 36 and Route 39 (U.S. Route 20A). Access for emergency vehicles will be accommodated during the closure, DOT said in a news release.

Court Street at the Route 63 intersection will be closed to traffic for about one month in order to complete the construction and tie-in of the new concrete roundabout, just south of the bridge. A detour will be in place to use Route 39 (Main Street) in Geneseo to Route 63.

All construction activities are weather dependent and subject to change, the DOT said.

The projects began last summer, with the new bridge being built directly west of the existing bridge, which has remained in use throughout the project.

The new bridge replaces a truss bridge that is nearly 70 years old with a modern two-span, multi-girder bridge featuring 12-foot-wide travel lanes and 8-foot-wide shoulders that will better accommodate commercial vehicle traffic.

The roundabout, which has three points of entry, is designed to reduce congestion and enhance safety at the intersection, according to DOT.

Roundabouts help smooth traffic flow and reduce the severity of vehicular crashes, the DOT said.

Both the bridge and roundabout will have concrete pavement.
