City of American Canyon - SR 29 & Napa Junction Road

Coastland’s design of the SR 29 & Napa Junction Road intersection involved widening the roadway to accommodate additional travel lanes and dedicated left- and right-turn pockets. Improvements also consist of ADA-compliant ramps, street lighting, traffic signal modification, sewer pipeline replacement, grading, curb, gutter and sidewalk, striping, signage, drainage, landscape and irrigation, and utility relocation/undergrounding. A large portion of the intersection widening improvements are located within the Caltrans right-of-way.
