Travel directions
I-11 rond Boulder City.
I-11 begins at the border with Arizona, which is formed by the Colorado River. The Mike O’Callaghan-Pat Tillman Memorial Bridge is a large arch bridge spanning the river’s gorge near the Hoover Dam. The highway has 2×2 lanes and first leads through very mountainous terrain, but the height differences are smaller around Boulder City. The highway loops around the south side of Boulder City and intersects with US 95. The highway then heads northwest into the Las Vegas metropolitan area.
The first suburb is Henderson and I-11 immediately has 2×3 lanes. On the west side of Henderson, Interstate 215 joins, which forms the Las Vegas ring road. From here, the route is formally numbered as Interstate 515. The highway then runs through a suburban area in southeast Las Vegas, with numerous connections to the underlying road network. The entire highway has 2×3 lanes here. Near downtown Las Vegas, I-11 ends at an interchange with Interstate 15. US 95 then continues as a freeway to the northwest.

History
Interstate 11 was not included in the original Interstate Highways plan in the 1950s because both Phoenix and Las Vegas were insignificant desert towns at the time. This changed from the 1960s and especially the 1990s when both cities grew explosively, partly due to immigration and a huge migration from California, as house prices there became unaffordable.
Interstate 515
Construction on the highway began in 1982 and it was the first highway built in the Las Vegas metropolitan area after I-15. The highway was built southeast from I-15, reaching Charleston Boulevard in 1984, Tropicana Avenue in 1986, Russell Road in 1988, and Lake Mead Drive in 1990. By 1994, the highway was completed to Boulder Highway southeast of Henderson. Since that year, I-515 has also been used as a number, before that the highway was designated as US 95. New signage was installed in 2019, renumbering the portion of I-515 south of I-215 in Henderson as I-11.
Hoover Dam Bypass
The Hoover Dam Bypass project involved the construction of the Mike O’Callaghan-Pat Tillman Memorial Bridge, a large concrete arch bridge over the Colorado River, near the Hoover Dam. This also built 4 kilometers of freeway on the Nevada side to just east of Boulder City. This section opened to traffic on October 19, 2010.
Boulder City Bypass
On April 6, 2015, construction began on a 15-mile route of Interstate 11 around Boulder City. Construction of the $318 million project took 3 years. On August 16, 2017, a small section of 2 miles south through the Railroad Pass at the end of I-515 opened up, providing access only to old US 93. On January 27, 2018, it opened 3 kilometers from that part to the north.
On May 23, 2018, the first proper 4-kilometer section of I-11 through the Railroad Pass, between Henderson and the junction with US 95, opened . On August 9, the 19-kilometer freeway around Boulder City, including a scenic overlook. This provided a continuous freeway from the Arizona border to I-15 in Las Vegas.

Future
Las Vegas
There were three options for directing I-11 through Las Vegas:
- on current I-515 (US 95) right through town, an existing freeway
- via I-215 along the south and west sides of town, an existing freeway
- via a newly constructed eastern bypass and I-215 along the north side of the city
In 2022 it became clear that routing over the existing I-515/US 95 made the most sense.
Las Vegas-Reno
It has been proposed to extend I-11 from Las Vegas to Reno, Nevada’s second largest city. This route is approximately 715 kilometers long. Small sections have already been run as freeway in Las Vegas (US 95) and at Reno (I-580). Approximately 625 kilometers of the I-11 needs to be newly constructed. Due to the very low traffic volumes on the existing US 95, there is little chance that this will happen in the foreseeable future.
Traffic intensities
Every day, 16,000 vehicles drive on the bridge over the Colorado River on the border with Arizona. This increases to 50,000 vehicles through the Railroad Pass and 100,000 vehicles in Henderson.
