I-390/I-490/Route 31 Interchange Improvement

The I-390/I-490/Route 31 Interchange Improvement Project in Monroe County New York was completed, on schedule and under budget. The multi-phase series of infrastructure investments repaired or replaced seven bridges, created a new exit ramp connecting Interstate 390 to Lyell Avenue, constructed the new southbound I-390 Flyover, and made several other improvements to ease travel, reduce congestion, and enhance safety along this vital Rochester area corridor.

The McLaren Difference: Applied Ingenuity

McLaren’s Bridge/Highway/Rail Infrastructure engineering team worked as consultants to Cold Spring Construction Co., providing design and construction quality control services on the Design-Build project’s final phases. Phase Three encompassed the addition of an exit-only lane on I-390 to Chili Ave and the development of the new Interstate 390 Flyover that allows southbound through traffic to travel above the busy interchange.

Construction of the Flyover involved the building of three new bridges to cross over I-490 eastbound, I-490 westbound and a newly reconfigured ramp connecting I-490 westbound to I-390 southbound. Additionally, the aging Buffalo Road (State Route 33) Bridge over I-390 was replaced with a modern, multi-girder bridge to accommodate the new traffic pattern. The construction of nearly 15,000 feet of new concrete sound walls helped mitigate noise impacts for nearby residents. Additionally, Phase Four widened and resurfaced the roadway along Lyell Avenue (Route 31) between Route 390 and Howard Road.

To assure a quality build and ensure work progressed according to plan, McLaren’s infrastructure team oversaw the development and implementation of the project quality manual, served as direct contacts between the NYSDOT and Design Build Team, and performed quarterly quality audits.

The I-390/I-490/Route 31 Interchange Improvement Project is an integral part of “Finger Lakes Forward,” the region’s comprehensive blueprint to generate robust economic growth and community development. New York State has already invested more than $8.07 billion in the region since 2012 to lay the groundwork for the plan – investing in key industries including photonics, agriculture, and food production, and advanced manufacturing.
