NYS Thruway Exits 39 to 40 Reconstruction

The New York State Thruway Authority sought to completely reconstruct 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).

Erdman Anthony was selected to provide construction inspection services for the project.

The project included significant pavement widening and crossovers to accommodate four lanes of traffic during each 5-mile-long stage.

Features included:

• Continuous temporary concrete median barriers
• Culvert replacements
• Drainage improvements
• Box-outs
• Significant undercuts
• New permeable sub-base and 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.

The reconstruction updated and improved this vital infrastructure.

Off-site wetland mitigation for 12 acres was also part of the project. Safe maintenance and protection of traffic were key considerations.
