Interstate 15 (I-15) is an
The entire route of I-15 is designated the Las Vegas Freeway.[1]
Route description

From Silverado Ranch Boulevard to
The Interstate meets I-215 at the Southern Beltway Interchange, which provides access to Henderson and Harry Reid International Airport. Originally, this interchange was termed Son of Spaghetti Bowl by the Las Vegas Review-Journal when it was built.[citation needed]
I-15 travels along the west side of the Las Vegas Strip corridor and just west of downtown Las Vegas just before its junction with I-515 and US 95 (the "Spaghetti Bowl" interchange). Then, the Interstate enters North Las Vegas and continues to run roughly parallel to Las Vegas Boulevard (old US 91) as it leaves the Las Vegas urban limits near the northern junction with the Clark County 215 beltway.[4]
Once I-15 leaves North Las Vegas, the freeway travels northeast and crosses the Muddy River at Glendale and then climbs up onto the Mormon Mesa. At Mesquite, the freeway then crosses the Arizona state line and cuts through the extreme northwestern corner of Arizona through the Virgin River Gorge before entering Utah.
History
Early routes
The general location of the I-15 corridor through Nevada can be traced as far back as the early 1900s. Regular automobile travel through southern Nevada was established by 1914 along the Arrowhead Trail, a road connecting Los Angeles and Salt Lake City.[5] In 1919, the Nevada Legislature amended its newly adopted highway law to add SR 6, which was described as "Commencing at the Arizona line near Mesquite and running southwesterly over what is now known as the Arrow Head [sic] trail through Las Vegas to Jean, Nevada."[6] Two years later, the route was revised to pass through Las Vegas and head "via Jean or Goodsprings to a junction with the California state highway system."[7]
US 91 / SR 6 began at Primm and followed the Los Angeles Highway toward Las Vegas. Within the city limits, it ran along Fifth Street (now
The route eventually gained two other highway overlaps. US 466 was christened in 1934, and was routed concurrently along US 91 from California to downtown Las Vegas before heading southeast to Hoover Dam (the route was deleted in 1971).[11] Also, in 1936, US 93 was extended from its 1932 southern terminus at Glendale, over US 91 to downtown Las Vegas on its way to Hoover Dam.[12]
Interstate development
A new alignment of US 91 was completed in 1955. This bypassed both Bunkerville and Mesquite to the northwest, along what would become the future path of I-15.[13] The original alignment through Bunkerville is now SR 170.
The passage of the
The final sections of I-15 to be completed were in North Las Vegas and near the Arizona state line.[17] Both of these sections were completed in 1974. The US 91 designation, which had remained on its original alignment during the construction of the Interstate, was made redundant by the new freeway and was removed in 1974.[18]
Between Las Vegas and the California state line, the Nevada Department of Transportation (NDOT) added call boxes at one-mile (1.6 km) intervals in the mid-2000s, for motorists with vehicle problems and without cell phone service. This was done as part of a larger project that expanded this portion of the freeway to three travel lanes in each direction to coordinate with a similar effort in California.
In August 2011, I-15 in southern Las Vegas was substantially expanded. This involved adding between 30 and 85% more capacity and involved the use of the Big Stan drill rig.[19]
Future
Due to heavy traffic, there are plans by the
In 2020, Brightline signed a 50-year lease for use of the I-15 right-of-way between Victor Valley and the Las Vegas Valley for use in their Brightline West high-speed rail service.[23][24]
