Engineering Project Case Studies | Erdman Anthony


This four-year project completely reconstructed 15 miles of the New York State Thruway and rehabilitated four bridges between Interchanges 39 (I-690 in Syracuse) and 40 (Route 34 in Weedsport). 

The project included significant pavement widening and crossovers to accommodate four lanes of traffic during each 5-mile-long stage. It also included continuous temporary concrete median barriers, culvert replacements, drainage improvements, box-outs, significant undercuts, new permeable sub-base, new concrete pavement, extra-wide shoulders to accommodate later stages of traffic, new signs, delineators, and landscaping. 

The bridge work included significant repairs to two large culverts, widening and deck replacement of the bridges over Skaneateles Creek, and replacement of the Cold Spring Brook bridges. Off-site wetland mitigation for 12 acres was also part of the project. Safe maintenance and protection of traffic were key considerations. Erdman Anthony provided nine of the 15 inspectors for this project.
