Project Update:  

Construction of bridge structure footings will begin on June 4 at 1 a.m. with concrete placement. In upcoming weeks, additional night work will occur for bridge wall and deck concrete placement. This work will require lights and equipment that will produce standard construction noise.

Project Description

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.
