Brightline West, the company developing a high-speed rail system connecting Las Vegas and Rancho Cucamonga, California, will be conducting field investigation work this week along the Interstate 15 corridor in Southern California. The work includes geotechnical borings, utility potholing, and land surveying to support the planned 218-mile rail project.

Why it matters

The Brightline West high-speed rail project is a major infrastructure initiative that aims to provide a faster transportation alternative between Las Vegas and the Inland Empire region of California. The field work represents an important step forward in the project's development as Brightline West prepares for the construction phase.

The details

The field investigation work will take place primarily during daytime hours, with some nighttime activity to minimize disruption to I-15 traffic. Short-term closures of freeway shoulders may be required in certain areas. Motorists are advised to exercise caution and follow all posted signage in the work zones.
