The 11 – Boulder City Bypass

Boulder City Bypass Map


With the Clark County Commission’s passage of the local Fuel Tax Indexing Ordinance on September 3, 2013, the Regional Transportation Commission of Southern Nevada (RTC) has decided to move forward with the development of the I-11 Boulder City Bypass using a Design-Build contracting method.  The RTC will fund the proposed I-11 Boulder City Bypass Design-Build Project with Clark County-issued municipal debt.  Private financing will not be sought for this project. Additionally, tolling of the project is no longer proposed, and the construction of toll facilities will not be included.

The RTC anticipates using a two-step process to engage a Design-Builder to design and construct the I-11 Boulder City Bypass Design-Build Project.  The first step will commence with the RTC’s issuance of a Request for Qualifications (RFQ).  The RFQ will be issued on or about mid-October 2013.  The RTC will establish a short list from among the Respondents submitting Statements of Qualifications (SOQs) in response to the RFQ.  In the second step, not more than 3 shortlisted Respondents will be issued a Request for Proposals and will be asked to submit technical/price proposals for the design and construction of the project under a Design-Build Contract.

It is expected that a Design-Build Contract will be awarded in the fall of 2014, with up to 3 years required for construction.


The proposed I-11 Boulder City Bypass Design-Build Project will construct approximately 12 miles of new freeway around the southern and eastern perimeter of Boulder City from US-95 to US-93.  The project will include the design and construction of a four lane access controlled freeway with a new interchange at US-95 and a reconfigured interchange at the US-93/SR-172 Hoover Dam Exit. Major project elements will include extensive rock excavation, nine bridges, a scenic view parking area overlooking Lake Mead, drainage culverts and environmental mitigation.  A portion of the project will be constructed through a ridge of the El Dorado Mountains.

The Final Environmental Impact Statement was completed in 2005 and a Record of Decision has been received.  An Environmental Re-evaluation was approved in February, 2013.  The RTC is in the process of acquiring the required rights-of-way from three public agencies, the City of Boulder City, the National Park Service and the Western Area Power Administration.  No private properties are required for the construction of the Project.

The U.S. Congress, with its passage of the Moving Ahead for Progress in the 21st Century Act (MAP-21) in 2012, designated the planned freeway between Las Vegas and Phoenix as the “Future I-11.”  The Boulder City Bypass will be constructed as a portion of Nevada’s Future I-11.

The Project will be coordinated with the Nevada Department of Transportation, who will provide State oversight for the Project and will contemporaneously construct the northernmost 3 miles of the Boulder City Bypass adjoining the Project.
