The Boulder City Bypass

The Boulder City Bypass Project involves traffic improvements to US 93 in the Cities of Henderson and Boulder City, Nevada, area. Project limits are between a western boundary at the end of Interstate 515 on US 93/US 95 in Henderson (US 95 MP 59.10), approximately 1 mile north of the Railroad Pass Hotel and Casino, and an eastern boundary on US 93, approximately 0.75 mile east of the Hacienda Hotel and Casino.
The Nevada Department of Transportation (NDOT) and Federal Highway Administration (FHWA) have completed an Environmental Impact Statement and received a Record of Decision on December 8, 2005. Alternative D (Southern Bypass) was the selected alternative to improve the US 93 corridor from the Foothills Grade Separation on US 93/US 95 to the western end of the Hoover Dam Bypass. As part of the environmental process, the project purpose and need was to:

• Reduce traffic problems in the vicinity of Boulder City
• Extend freeway status to the U.S. 93/95 interchange
• Improve operations at the junction of U.S. 93/95
• Create a safer transportation corridor
• Accommodate future transportation demand
• Improve system linkage on U.S. 93 and maintaining route continuity

The project is separated into two phases, shown in the exhibit below. A Landscape and Aesthetics Plan is being developed for both of these phases. A set of Interim Safety Improvements have also been identified to improve the local Boulder City roadways in advance of the scheduled June 2010 opening of the Hoover Dam Bypass.
