Las Vegas, Nevada

I-11 Boulder City Bypass

Completed in 2018

Las Vegas and Phoenix are the only two cities in the nation with populations of more than one million people that are not currently linked by an interstate.

The first phase of I-11 will construct approximately 15 miles of new freeway around the southern and eastern perimeter of Boulder City from I-515 to US-93. The project will include the design and construction of a four-lane access-controlled freeway with a new interchange at US-95 and a reconfigured interchange at the US-93/SR-172 Hoover Dam Exit.

Major project elements will include extensive rock excavation, nine bridges, a scenic view parking area overlooking Lake Mead, drainage culverts and environmental mitigation. A portion of the project will be constructed through a ridge of the El Dorado Mountains
