High desert corridor

In anticipation of future growth and to alleviate existing congestion on east/west corridors such as I-210, I-10, SR-60 and SR-138, the California Department of Transportation (Caltrans) and the Los Angeles County Metropolitan Transportation Authority (Metro) completed the High Desert Corridor Final Environmental Impact Statement (EIS)/Environmental Impact Report (EIR) in 2016.

AA developed a comprehensive outreach program that encompasses and balances the needs of state and local transportation agencies, elected officials, community and business stakeholders for both Los Angeles and San Bernardino counties.  AA has collaborated with Civic Resource Group to bring the project area maps to life by developing the GeoSocial Interactive Map. This Google-based, dynamic mapping and social media system is designed to allow the user to view the project area and zoom into specific areas of interest like the alternatives and variations, cities/towns, and proposed freeway on-/off-ramps.
