The Solano Transportation Authority (STA), Solano County, and the City of Vallejo, in cooperation with the California Department of Transportation (Department), propose to modify the existing Interstate 80 (I-80)/Redwood Parkway interchange to a tight diamond configuration, realign Fairgrounds Drive to a tee intersection north of the I-80 westbound ramps, widen Fairgrounds Drive between Redwood Street and State Route 37 (SR 37), widen the westbound exit ramp from SR 37 to Fairgrounds Drive, and improve the intersections at the SR 37/Fairgrounds Drive Interchange. Current transportation issues in this area include poor circulation during peak commute periods, long delays at intersections, short acceleration and deceleration areas, and limited sight distance. In addition, the existing capacity of the roadways in this area would not accommodate the projected future traffic volumes.

A non-single occupant vehicle opportunities and constraints analysis is also presented.
