I-80/Hiddenbrooke Parkway Interchange Project
The City of Vallejo is proposing operational improvements at the I-80/Hiddenbrooke Parkway interchange to address existing and future vehicle queues on Hiddenbrooke Parkway. The project will convert the existing stop sign-controlled intersections of the I-80 ramps with American Canyon Road and Hiddenbrooke Parkway, and the intersection of Hiddenbrooke Parkway and McGary Road, into roundabouts. Conversion of these intersections to roundabouts will not require modification of the existing American Canyon Road overcrossing of I-80. The project will require modification of the on and off-ramps where they intersect with local roads but would not involve changes to the ramp connections with I-80 or the existing mainline of the freeway. All proposed improvements would occur within existing State and local public rights of way. No displacement of an existing business or homes, nor the acquisition of private property would be required. In addition, no nonstandard design features are necessary to implement the project.
