Brightline West High Speed Train Roadwork this Week on I-15

SOUTHERN CALIFORNIA, CA. (Pain In The Pass) >> Brightline West announces more updates to field investigation work in Southern California within the proposed rail corridor within Interstate 15 right-of-way. Field work has started already for the Brightline West that will connect Las Vegas and Southern California with America’s first true high-speed rail system.

Field investigation work includes geotechnical borings and samplings, utility potholing and land surveying. Work will take place primarily during daytime hours, with some work at night to minimize disruption to traffic. In some instances, short term closures of freeway shoulders will be required. All work will be done in compliance with applicable environmental regulations and in coordination with Caltrans and the Nevada Department of Transportation.

This week’s project areas are listed below. Motorists should proceed with extra caution through work zones and adhere to posted detour signs, speed limits, and other signage.

Near Main Street to Oak Hill Road on I-15

Geotechnical borings will continue on the I-15 freeway in the center median, starting from approximately 1/2-mile north of Main Street to Oak Hill Road. This work is scheduled from Monday, February 23rd through Friday, February 27th, between 8am and 3pm.

Highway 138 to Devore

Geotechnical borings will continue at night on the southbound interior shoulder of the I-15 freeway, between the Hwy 138 interchange in the Cajon Pass to the I-215 interchange in Devore. The southbound lane #1 will be closed on Thursday, February 26th and Friday, February 27th, between 8pm and 4am.

*Times can subject to change and could go longer or start earlier. Please use caution and remember to reduce your speed when approaching and driving through the construction zones. Schedules are subject to change due to inclement weather or construction issues.
