Brightline West has announced an additional round of field investigation work projects along Interstate 15 in Southern California.

The field work, for the company’s 218-mile high-speed rail project from Las Vegas to Rancho Cucamonga, will occur at various locations within the rail corridor along the I-15 right-of-way.

Brightline West kicks off July with more fieldwork testing for its high-speed rail project along Interstate 15. Work will be conducted on the Southern California side of the Las Vegas to Rancho Cucamonga project.

The work will include geotechnical borings and samplings, utility potholing and land surveying, according to Brightline West.

Work will take place primarily during daytime hours with some activity at night to minimize disruption to traffic. In some instances, short-term closures of freeway shoulders will be required.

Brightline West said that work will be done in compliance with applicable environmental regulations and in coordination with Caltrans.

Motorists should proceed cautiously through work zones and adhere to posted detour signs, speed limits and other signage.

Dates and times are subject to change, as operations are weather-dependent, Brightline officials stated.

Updated Brightline West project areas in Southern California include:

Basin Road and I-15: From 7 a.m. to 4 p.m. from June 30 through July 3, crews will work on geotechnical borings on I-15 for the future wildlife crossings. The project location is approximately 3.5 miles south of Basin Road (Cady Mountain) on the northbound and southbound exterior shoulders; and in the freeway center median approximately 4 miles south of Basin Road (Cady Mountain).
Duncan Canyon and I-15: From 7 a.m. to 3 p.m. on July 1, bridge potholing will be performed at the interchanges of I-15 from Ducan Canyon to the State Route 210 eastbound to northbound connector ramp.
Mojave Drive and I-15: Between 10 p.m. and 4 a.m. on July 2, bridge potholing will be performed at the interchanges of the I-15 from Mojave Drive to Bear Valley Road.

Oak Hill Road and I-15: From 7 a.m. to 5 p.m. on July 1, infiltration testing will be performed on the I-15 gore area of the Oak Hill Road northbound off-ramp.
Alvord Road and I-15: From 7 a.m. to 5 p.m. on July 2, infiltration testing will be performed in the I-15 center median just south of Alvord Road.

Brightline West’s $12 billion Las Vegas to Southern California high-speed rail project includes a flagship passenger station in Las Vegas and stops in Apple Valley, Hesperia and Rancho Cucamonga.

In February 2025, Nevada Department of Transportation officials were told by Brightline officials that construction of the rail project would begin in spring 2025.
