Document Description
Caltrans District 4 and the City of Vacaville propose traffic, pedestrian, and bicycle improvements to the Vaca Valley Parkway corridor from west of the East Monte Vista Avenue/Crocker Drive intersection to east of the I-505 northbound on- and off-ramp intersection. The project site is between Post Miles R1.2 and R1.7 on I-505, primarily located within the Caltrans and City ROW and surrounded by development, in Solano County, California.
The project would provide a new Class I separated facility for bicycle and pedestrian use across I-505, just south of the existing I-505/Vaca Valley Parkway interchange. The project would also replace three signalized and stop-controlled intersections at the Vaca Valley Parkway intersections with East Monte Vista Avenue/Crocker Drive and the I-505 southbound and northbound on-and-off-ramps with roundabouts.
