Safety was the primary objective for interim improvements NDOT made on U.S. 93 at the following locations:

  • Lake Mountain Drive- islands to enhance safety in the following ways:
    • Provides raised median to delineate intersection access.
    • Provides a refuge for vehicles turning left to accelerate into U.S. 93 traffic.Provides a protected southbound right turn to allow for acceleration into the adjacent traffic flow.
  • Pacifica: islands here to provide similar safety enhancements.
  • Ville Drive is also similar to Lake Mountain Drive. These enhancements should be especially effective near the top of the grade.

Other improvements include overhead signage south of Nevada Way, and rumble strips just north of Nevada Way to alert southbound traffic of the upcoming intersection.

U.S. 93 Emergency Widening

After the opening of the Hoover Dam Bypass Bridge in October 2010, congestion along U.S. 93 drastically increased, especially on weekends and holidays through the 5.5 mile bottlenecked corridor. Due to concerns of community leaders and residents of Boulder City over safety and increased traffic, NDOT "fast-tracked" a project to alleviate congestion in Boulder City. The project was a showcase of collaboration and seamless coordination with NDOT, ADOT, RTC's FAST, National Park Service, Boulder City and Bullhead City for reinstatement of truck restrictions and other traffic-related issues during construction. The project was partially within Lake Mead National Recreation Area and sensitive environmental areas had to be taken into consideration. The 5.5-mile project widened the existing roadway to two lanes in each direction, included several operational and safety improvements and required multiple utility relocations.
