WAVERLY — A bridge over Quebec Brook will be replaced, closing traffic on Blue Mountain Road for about a month once work starts this fall.
Franklin County legislators awarded the contract for some of the work to BIDCO Marine Group Inc. of Buffalo for $132,502 on the recommendation of their consulting engineers, Barton and Loguidice P.C.
County Highway Superintendent Jonathan Hutchins said the bridge has been yellow flagged twice by the State Department of Transportation as a bridge in need of repair.
According to the U.S. Department of Transportation Federal Highway Transportation’s National Bridge Inventory Data, the 36.7-foot bridge and approach is 8.6 miles south of Santa Clara, was built in 1986 and has an average daily traffic of 428 vehicles.
During a 2010 inspection, it was determined that there was heavy scaling, wide cracks and “considerable scouring or erosion” of the culvert pipes.
“The bridge’s foundations are determined to be unstable,” the report states.
It estimated the repairs at $390,000.
Hutchins said the three galvanized culverts installed in 1986 have rusted and collapsed, prompting the decision to replace the entire crossing with a 16-by-40-foot single-lane bridge using steel and decking that were refurbished after other recent bridge projects that his department has performed.
For example, two of the four main girders and decking of a bridge replacement on Johnson Road in Malone were still in good enough shape to use, which lowers the county’s cost for the Blue Mountain Road job.
He said BIDCO will drive the supports and create the foundation for the bridge work, and his crews will build and install the steel, decking and the rest to complete the project.
Hutchins said a start date could come later this week and that, soon after, traffic would be closed on Blue Mountain Road and rerouted to an alternate road for about a month.
