Expressway planning activities
Overview
In 2003 and 2008, the Roads and Airports Department assessed the countywide expressway network for deficiencies and future capital improvement needs. In 2016, planned expressway improvements were re-prioritized for inclusion in the Measure B Expressway Improvement Program. This program dedicates $750 million from local sales tax receipts over a thirty-year period to address bottlenecks, improve traffic flow, and enhance pedestrian/bicycle capacity in the expressway network. These Measure B expressway improvements will be programmed and prioritized for delivery through development of the capital improvement plan.
