began widening US 93 to four lanes, and in some areas building a completely new roadway. In other places along the route, ADOT simply repaved the old highway and built two new lanes parallel to it. ADOT also began studying the possibility of adding grade separations to US 93 near the Santa Maria River to make the road a full freeway. At the same time Nevada and Arizona began looking at US 93's crossing of

on October 14, 2010, the vast majority of the roadway is now a four-lane divided highway. Still, with Phoenix and Las Vegas as the two largest neighboring cities in the United States not connected by Interstate Highway, leaders in both cities lobbied to include I-11 in the next Transportation Equity Act reauthorization. With the rise of the concept of "megapolitan" urban regions, I-11 is considered a key connector to unify the triangle formed by Las Vegas, Phoenix, and the

American Association of State Highway and Transportation Officials The American Association of State Highway and Transportation Officials (AASHTO) is a standards setting body which publishes specifications, test quality control, protocols, and guidelines that are used in highway design and construction through ...
(AASHTO) to request the creation of the I-11 designation between the Arizona state line and the I-215/I-515 Interchange in Henderson. AASHTO approved this request at their Spring 2014 Special Committee on US Route Numbering meeting, contingent on FHWA approval. On August 16, 2017, the first southbound segment was opened to traffic, with its accompanying northbound segment opening on January 27, 2018. On February 20, 2018, NDOT opened additional ramps connecting the new Railroad Pass Casino Road to both the Boulder City Parkway (current US 93 and US 95) and to I-11 (southbound exit and northbound entrance). The final portion of Phase 1, between the new casino access road and US 95, opened on May 23, 2018. On August 9, 2018, Phase 2 was opened to traffic, officially completing the Boulder City Bypass. Phase 2, which began construction on April 6, 2015, was expected to open by October 2018; however, in May 2018, the RTC announced that the section would be open by June 2018, three months ahead of schedule. That opening date was subsequently pushed back to August 9, 2018, as it was still in the post-construction stage. In March 2019, NDOT replaced I-515 signs along its southernmost stretch with I-11 signs. In July 2022, NDOT decided to route I-11 along the existing alignments of I-515/US 93/US 95 to downtown Las Vegas, then running concurrently with US 95 northwest to SR 157 rather than use I-215 or construct a new corridor as had been proposed.

on US 95. While the bulk of US 93 through Arizona has been upgraded to four lanes, some portions of the corridor are not built to Interstate Highway standards, as there are scattered at-grade intersections, substandard roadway and shoulder widths, median crossovers, and other deficiencies. Part of these dual roadways are repaved, re-striped sections of very old parts of US 93. Farther south, a direct system interchange with US 93 and I-40 is planned to eliminate the bottleneck at Beale Street in western Kingman. The first phase of construction, planned to begin in 2024 and finish in 2026, will construct direct connectors from westbound I-40 to northbound US 93 and from southbound US 93 to eastbound I-40. The remaining movements between US 93 and I-40 will continue to use the existing Beale Street interchange until traffic demands warrant and the second phase can be funded. , Phase 4 of the project is under construction. The US 93 Corridor Improvement Project will finish what was started in 1998 and connect the four sections of the divided highway to Wickenburg, allowing more traffic on these congested roads. Up north, a direct interchange with I-40 and US 93 is planned. This will eliminate the existing Cedar Hills interchange to allow a better flow of traffic directly onto US 93 from I-40. US 93 will be cosigned as I-11 once it is built to Interstate standards.

In July 2012, Nevada's Transportation Board awarded $2.5 million in contracts to a team of consultants to study I-11's feasibility and its environmental and economic consequences.
