Summerlin Parkway Site - Project Overview

The City of Las Vegas and the Regional Transportation Commission of Southern Nevada (RTC), in cooperation with the Nevada Department of Transportation (NDOT) and the Federal Highway Administration (FHWA), are proposing transportation improvements to the Summerlin Parkway corridor between Clark County Route 215 Bruce Woodbury Beltway and U.S. 95 in Las Vegas, Nevada.

Study Area

The proposed Project is planned to expand the existing Summerlin Parkway by adding two additional through lanes in each direction. One of the two lanes is being studied to be a managed lane (i.e. high-occupancy vehicle lane). In addition to the additional through lanes, auxiliary lanes between the ramps are proposed to facilitate merging and weaving.

The purpose of the Project is to accommodate present and future traffic demands and provide improved operational characteristics (level of service (LOS)) within the Summerlin Parkway corridor. Commercial and residential development occurring and planned within and west of the Project corridor, as well as regional growth, is generating the need for this Project. This Project is in compliance with the current Transportation Improvement Program (TIP) prepared by the RTC.

The planning process for the proposed improvements to the Summerlin Parkway corridor will include studies of the Project impacts and the preparation of a federal environmental document to meet the objectives of the National Environmental Policy Act (NEPA)

What is NEPA?

The environmental document will be developed based on the information and findings of the engineering studies, addressing the environmental impacts and needed mitigation measures if the project goes forward.

Potential improvements may include:

Lighting - A lighting analysis will be performed to determine the type, location, and spacing of lights.

Soundwalls in select locations - A noise assessment study will be conducted to measure traffic noise and determine the need for soundwall based upon the projected traffic noise conditions.

Landscape Treatments - Landscape treatments will include restoring the existing landscaping and monuments along the corridor.

Aesthetic Treatments - Bridge structure widening and retaining/soundwalls may incorporate aesthetic treatments similar to recent improvements at Durango Drive and Anasazi Drive.

Regional Trail - The RTC Trail Master Plan includes a trail along the project corridor. Portions of the trail are existing including the Bonanza Trail from Durango Drive to Buffalo. Provisions for a future trail will be provided for as part of this project.

Intelligent Transportation Systems (ITS) - The project may include ITS elements consisting of ramp metering, dynamic message signs, communication systems, and CCTV (incident management).

Following the completion of the environmental document, final design drawings will be prepared for construction.

The Project is funded by the Regional Transportation Commission of Southern Nevada (RTC) and possibly FHWA.
