Project Benefits

Vehicles will back up on Interstate 80 where the westbound I-80 connector ramp converges with northbound State Highway 65. Recurring traffic demand exceeds the current design capacity of the Galleria Boulevard/Stanford Ranch Road/Highway 65 northbound ramps and adjacent transportation facilities, creating traffic operations, and safety issues. These issues result in high delays and wasted fuel, both of which will be exacerbated by traffic from future population and employment growth. This project will improve safety and ease congestion.
