Petaluma Boulevard South was one of many city streets across the Bay Area to receive a makeover through a “road diet” project. A road diet redesigns the street by removing or narrowing traffic lanes. The goal is to slow down vehicular traffic, speed up city buses, install dedicated bike lanes and/or other public transit systems such as light rail, and improve pedestrian safety. It is part of a national and international movement to create a “complete street” which promotes transportation choices other than automobile travel.
Engineering design, environmental studies, and construction support were provided to the City of Petaluma for their project. It reduced four 9.5-foot wide traffic lanes to two wider 12-foot lanes, created a continuous center two-way left turn lane, add bike lanes, and created larger 8-foot wide parking spaces which will reduce side-swipe collisions and on-street parallel parking efforts. Pedestrian safety was also increased as the road diet reduced the distance pedestrians were vulnerable to car traffic.
Overall work included:
- Micro-surfacing existing pavement
- New pavement striping, markings and markers, traffic signal modifications
- Traffic loop replacement
- Installation of ADA compliant curb ramps, audible pedestrian crossing signals, bike racks, and benches
