During the morning rush hour, the Winton Road exit off I-590 southbound would become extremely backed up. Motorists trying to access I-590 from Winton Road in the afternoon would likewise experience long backups and delays. To solve this problem, the New York State Department of Transportation chose to construct a Diverging Diamond Interchange—an innovative design that delivers smoother traffic flow, reduces backups and delays, and improves motorist and pedestrian safety. In addition to the safety factors, the Diverging Diamond Interchange was chosen over other options because it would also take the shortest amount of time to construct, require the least amount of real estate, and provide the best cost value.
Erdman Anthony prepared the 3D model for construction of this interchange. Our services also included generating cross-sections of the corridor and traffic signal design, curb island details, temporary traffic signals, and the construction cost estimate. Erdman Anthony was also responsible for generating handout materials and mailers for the public informational meetings held before opening the interchange. A video generated by Erdman Anthony explained how to drive, walk, and bike safely through the novel interchange.
