Marin-Sonoma Narrows

BKF worked with the Sonoma County Transportation Authority (SCTA), Transportation Authority of Marin (TAM), and Caltrans, as well as adjacent stakeholders to provide Segments A3, B1 C2 HOV improvements on US 101. As the prime consultant, BKF provided project management, PA&ED work and PS&E construction documents. The MSN A3 project involved the lane widening, including cross-slope and profile grade corrections and improved drainage systems, for a 1.7-mile stretch through Novato. The design included compatibility with future improvements along southbound US 101.
