The Chautauqua County Department of Public Facilities said the closure is to complete the top course asphalt paving surface on the bridge.

Other work will include the installation of a crosswalk for the Riverwalk trail, roadway striping and remaining landscaping. Crews will also be adjusting manhole covers and utility risers along with miscellaneous milling before paving work begins.

“The Chautauqua County Department of Public Facilities appreciates the public’s patience and understanding while final construction activities are completed,” the department said in a statement. “Please follow the posted detours.”

Meanwhile, contractors from Highland Masonry & Restoration of West Seneca were at the bridge Tuesday installing tops to the concrete bridge walls. The tops, which weigh about 400 to 500 pounds each, were put in place using a forklift.

The $4.2 million county project, of which the federal government funded 80 percent, included the rehabilitation of the bridge in addition to new bridge walls, approaches and asphalt paving.
