Project Description

This project is the continuation of previous efforts undertaken by the City of Las Vegas to study improvements to Charleston Boulevard at the I-515 interchange, combined with ongoing efforts by the Nevada Department of Transportation (NDOT) to identify and prioritize improvements along the I-515 corridor between I-15 and Wyoming Avenue. The intent of the proposed I-515/Charleston Boulevard Interchange project is to improve traffic capacity, operations, and safety on both Charleston Boulevard and I-515.
