Unusual engineering approaches, careful studies of earth and water movements, and a multi-organizational project team that worked cooperatively lead to the successful replacement of the bridge over Beards Creek, on U.S. Route 20A and State Route 39, after being closed for 3.5 years. The $3 million bridge and approach roadways were designed to have the ability to adapt to possible soil creep in the future. The New York State Department of Transportation estimates that an average of 5,350 vehicles will cross the bridge daily.
