The High Desert Corridor (HDC) project is considering construction of a new multi-modal link between State Route (SR)-14 in Los Angeles County and SR-18 in San Bernardino County. This project would connect some of the fastest growing residential, commercial and industrial areas in Southern California, including the cities of Palmdale, Lancaster, Adelanto, Victorville and the Town of Apple Valley.
In anticipation of this 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) partner agencies completed the HDC Draft Environmental Impact Statement/Report (EIS/EIR) and Appendices in late 2014. The environmental effort is to study alternatives to promote transportation mobility, enhance safety, and improve air quality in the region.
Caltrans and Metro studied five functional alternatives and four physical variations in the Draft EIS/EIR and identified the Preferred Alternative (PA) in July 2015. The PA is a multipurpose alternative that includes freeway/tollway with high speed rail in the median along with the green energy corridor and the bikeway. The PA includes two previously considered variations (Variations D and B1) as part of the alignment.
- Variation D - located in Lake Los Angeles, will reduce the number of residential displacements and avoid an existing vineyard.
- Variation B1 - located in Adelanto, will avoid impacts to several water wells supplying water to local communities.
The Final EIS/EIR is now complete and available for viewing below:
