Starr Interchange

Project Description

Starr Interchange logo

The I-15/Starr Avenue Interchange adds a key link to one of the most highly traveled corridors in the country.  It will enhance local access and mobility by connecting Starr Avenue from the west side of I-15 at Dean Martin Drive to the east side of I-15 at Las Vegas Boulevard.  The project will help reduce crashes and alleviate existing and projected congestion on local streets that access I-15 and I-215 via Eastern Avenue, Cactus Avenue, and St. Rose Parkway.

The scope of this project is to design and construct the new interchange.  The design consists of raising the I-15 freeway over Starr Avenue, while Starr Avenue remains at its existing grade.
