Project Alternatives

HDC Functional Alternatives and physical variations carried forward for further study in the Draft EIS/EIR:

No Build Alternative

The No-Build (No Action) Alternative is exactly as it sounds – it proposes that no new corridor be built. Simply, the No-Build alternative represents future travel conditions without the HDC project, and is the baseline against which the other alternatives are measured. 

Freeway/Expressway Alternative (Avenue P-8, I-15 and SR-18) (With 4 Variations)

This Alternative consists of a combination of a controlled-access freeway and an expressway.  It generally follows Avenue P-8 in Los Angeles County, and south of El Mirage Rd in San Bernardino County, later extending to Air Expressway Rd near I-15 and curving south to terminate at Bear Valley Rd. This alternative, unlike the previous two, will also consider incorporation of green technologies and a new bikeway.

There are four slight variations that are being considered for this alternative, each representing a difference in how the freeway/expressway would curve and bend throughout the alignment:

Variation A

  • Near the City of Palmdale, the freeway/expressway would dip slightly south of the main alignment, approximately between 15th St East and Little Rock Wash.

Variation B (south)

  • East of the county line, the freeway/expressway would flare out slightly south of the main alignment between Oasis Rd and Coughlin Rd.
  • Variation B1 is another option in this area but is more direct and would require a shorter travel distance and would pass through Krey Airfield.

Variation D

Near the community of Lake Los Angeles, the freeway/expressway would dip slightly south of the main alignment, just south of Avenue R approximately between 180th St East and 230th St East. Variation D would maintain geometries that would allow for High Speed Rail tracks.

Variation E

  • Near the cities of Adelanto and Victorville, the freeway/expressway would dip south of the federal prison.

Freeway/Tollway Alternative (Avenue P-8, I-15 and SR-18)

This Alternative follows the same physical alignment as the Freeway/Expressway Alternative with the addition of sections of the alignment operating as a tollway. The incorporation of green energy technologies and a bikeway will also be considered.

Freeway/Expressway Alternative with High Speed Rail Feeder Service 

This Alternative is the same as the Freeway/Expressway Alternative, with the addition of a High Speed Rail (HSR) Feeder Service between Palmdale and Victorville. The incorporation of green energy technologies and a bikeway will also be considered in this alternative.

Freeway/Tollway Alternative with High Speed Rail Feeder Service

This Alternative is the same as the Freeway/Tollway Alternative, with the addition of a High Speed Rail (HSR) Feeder Service between Palmdale and Victorville.  The incorporation of green energy technologies and a bikeway will also be considered.
