Another Stretch of America's Newest Interstate Opens Outside Las Vegas

Posted by Deputy Federal Highway Administrator Brandye L. Hendrickson

Another section of Interstate 11 opened this month in Boulder City, Nevada, not far from Las Vegas. The Nevada Department of Transportation in partnership with the Regional Transportation Commission of Southern Nevada are to be commended for completing the construction of the first phase of I-11. 

The Federal Highway Administration supported this outstanding project with nearly $400 million in federal funding.

It’s an exemplary project in supporting many of our goals, including enhanced safety, less congestion and more efficient movement of freight. 

The project’s benefits at the local level include removing truck traffic from Boulder City while providing truck operators an alternate and more direct route around the city, but I-11 overall is a regionally significant project.

It marks the first step in connecting Las Vegas and Phoenix – the country’s two largest metropolitan communities not currently linked by an interstate highway. These are the only two cities in the nation with populations of more than one million people that are not connected by interstate.

Although there is more work is ahead before completing the link -  Motorists commuting between Las Vegas and Arizona will get some congestion relief now that this first 15-mile portion of I-11 is open to traffic.

I-11 also supports one of the FHWA’s infrastructure goals by not only improving mobility and accessibility – but also stimulating economic growth, productivity and competitiveness. Travel and commerce between Arizona and Nevada will be easier and the region’s economic competitiveness will be enhanced.
