The I-15/Starr Avenue Interchange adds a key link to one of the most highly traveled corridors in Clark County. 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.
