Project Description

Phase 4 of the I-15 North Corridor consists of designing new ramps, flyovers and street connections to complete a system-to-system interchange configuration where the northern I-15 meets the Clark County 215 Las Vegas Beltway.

The project also includes the addition of I-15 southbound ramps for the Tropical Parkway interchange. The Tropical Parkway interchange will use the existing I-15 northbound ramps as modified to work in concert with new flyover ramps for the I-15/CC-215 interchange. The project will construct sections of Centennial Parkway and Tropical Parkway to provide needed connections.

The images above are preliminary designs of the completed project. 

Landscape & Aesthetics

Lage Design is the landscape architect responsible for the striking new freeway aesthetics made up of boulders and decorative rock, accented by boldly colorful polygonal roadside sculptures that convey the characteristics of water and its impact upon shaping both the natural and built environments.

The images above are preliminary designs of the completed project. 

What Are We Doing?

• Constructing new direct connect ramps between I-15 and Clark County 215 (Las Vegas Beltway) interchange
• Building I-15 southbound ramps and reconstructing I-15 northbound ramps for the I-15 and Tropical Parkway interchange
• Reconfiguring local streets to improve traffic flow around the interchange
• Providing landscape and aesthetic enhancements
