I-494 Airport Corridor

Solution: Prestressed bridge girders support the widening of a major Twin Cities transportation corridor while overcoming complex delivery challenges.

Delivering Reliable Precast Solutions for Minnesota Infrastructure

The I-494 Minneapolis Airport to Hwy 169 Project is a critical infrastructure initiative designed to reduce congestion, improve safety, and enhance mobility along one of the Twin Cities’ most traveled corridors. County Prestress & Precastsupplied prestressed concrete bridge girders for this multi-year Minnesota Department of Transportation (MnDOT) improvement project. Spanning approximately 9.5 miles between Eden Prairie and the Minneapolis–St. Paul International Airport, the I-494 expansion supports growing traffic demands and improves regional connectivity for commuters and freight carriers.

County Prestress & Precast manufactured and delivered a series of prestressed concrete girders — some as long as 155 feet — engineered for long-term durability and high-traffic performance. Deliveries required careful coordination due to tight turns and restricted local streets near the project site. County Prestress & Precast’s experienced transportation team navigated these challenges with specialized equipment and precise scheduling, ensuring safe and on-time delivery.

The use of prestressed concrete girders offers a dependable solution for accelerated bridge construction, enhancing efficiency while minimizing long-term maintenance requirements. As the I-494 corridor continues to expand, County Prestress & Precast products play a vital role in supporting Minnesota’s heavy highway infrastructure and future transportation development.
