This program, in combination with local matching funds, provides a funding source to complete the Orange County Master Plan of Arterial Highways. The program also provides for intersection improvements and other projects to help enhance street operations and reduce congestion. The program allocates funds through a competitive process and targets projects that help traffic the most by considering factors such as degree of congestion relief, cost effectiveness, project readiness, etc.

Local jurisdictions must provide a dollar-for-dollar match to qualify for funding, but can be rewarded with lower match requirements if they give priority to other key objectives, such as better road maintenance and regional signal synchronization. Roughly 1,000 miles of new street lanes remain to be completed, mostly in the form of widening existing streets to their ultimate planned width. Completion of the system will result in a more even traffic flow and efficient transportation network.

Another element of this program is funding for construction of railroad overpass or underpass grade separations where high volume streets are impacted by freight trains along the BNSF railroad in northern Orange County.
