Abstract

The bridge carrying U.S. Route 15 over the Cowanesque River in Lindley, New York, USA is a single-span steel truss constructed in 1942. On this vital trucking link, the traffic is composed of one-third trucks, totaling over 2300 trucks per day. If the bridge were closed for repairs, the subsequent detour would be 51 miles (82 km), causing significant hardship to many communities and businesses. TVGA Engineering, Surveying, P.C. (TVGA) examined options for addressing the inadequate remaining fatigue life of the subject bridge, including- (1) more frequent "100% hands-on" inspections, (2) replacement of rivets with high-strength bolt
