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 began in January to advance final stages of design in preparation for a groundbreaking. Brightline West 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.
