Yolo 80 Corridor Improvement Project


The I-80/US-50 corridor experiences a high travel demand which has lead to severe traffic congestion and impaired mobility along the route. The current travel demands have exceeded the highway design capacity, which has caused bottlenecks for the traveling public. Through the addition of additional bus/carpool lanes, bike/pedestrian crossings, improved signing & striping and rehabilitation work, we look to improve mobility across this impacted corridor.

Project Benefits
