Erdman Anthony provided construction inspection for this NYSDOT project to widen and rehabilitate 1.4 miles of Route 252 from 4 lanes to 6 lanes wide between Ridgeland Road and Marketplace Drive in Rochester, NY. The Route 15A intersection was widened for dual left turn lanes and a right turn lane for a total of 9 lanes. The work included a new closed drainage system with 900 feet of new 12' x 6' precast concrete box culvert. Other work included a raised center median, new curbing, sidewalks, 6 overhead signs and landscaping. Significant overhead and underground utility relocations were needed, as well as a 24" water main replacement and a sanitary sewer relocation.
Six new interconnected traffic signals were built. Complicated traffic staging was provided on site using lane shifts and nighttime lane closures. Erdman Anthony provided the Chief Inspector, Office Engineer, and 5 inspectors for this $16.5 million project.
