Featured Projects

El Paseo Drive Pedestrian Safety & Enhancement Project

Client: City of Palm Desert

The City of Palm Desert invested approximately $1M in pedestrian improvements along El Paseo Drive, the City’s premier shopping and entertainment corridor. Project improvements included high visibility, brightly colored intersection crosswalks, upgraded ADA access ramps, and painted bulb-outs at two major intersections along El Paseo. Other improvements included brightly painted, highly visible speed tables at three pedestrian-activated mid-block crossings controlled by rectangular rapid flashing beacons. Interwest prepared the plans, specifications and construction estimate for the design of these improvements in support of the City's goal of enhancing pedestrian safety and multi-modal transportation along El Paseo. Our team also provided project management support through the construction phase to project completion.

Citywide Bicycle Facilities Detection Improvement Project

Client: City of Lodi

This Active Transportation Program Grant-funded project upgraded 13 of the City’s major intersections with improvements including the installation of video and loop detection systems and enhanced, high-visibility bike lane striping and bike boxes. Interwest prepared the plans, specifications, and construction estimates for the design of these improvements intended to enhance operational safety and encourage cycling, citywide.
