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.
