[4] The Las Vegas Beltway begins in Henderson at the I-11 / US 93 / US 95 interchange, where traffic on westbound Nevada State Route 564 (SR 564, Lake Mead Parkway) defaults onto I-215 west.

From here, the beltway primarily follows the former Lake Mead Drive alignment west to the Pecos Road / Saint Rose Parkway (SR 146) interchange.

Passing Decatur Boulevard, two one-way frontage roads (which formerly carried the initial beltway facilities) appear on either side of the highway.

From there, the beltway continues nearly due east along the alignment of Centennial Parkway before entering northern North Las Vegas at Decatur Boulevard.

[6] The first section of I-215 opened to traffic in 1996 from I-15 to Warm Springs Road, including the Harry Reid Airport Connector and tunnel, which linked Harry Reid International Airport to southern metro Las Vegas without requiring motorists to use Tropicana Avenue or Russell Road to access the main passenger terminal.

The southeast leg of the beltway (except for the I-515 connection) was completed ahead of schedule in 1999, while the northern end was extended from Decatur Boulevard in 1998 to Tropicana Avenue by 2000.

The remaining sections in the western and northern legs of the beltway were completed by 2003—either in their final, full freeway mode, or in one of two lesser interim configurations.

Since the Nevada Department of Transportation (NDOT) does not cosign state routes along Interstate highways, SR 146 was truncated to its current eastern terminus at I-215.

[7] The Board approved a resolution recognizing Republican Clark County Commissioner Bruce L. Woodbury for his many years and efforts in the future of transportation in the valley.

[8] Begun in 2012 and completed in 2014, construction by the Clark County Department of Public Works built the northern beltway segment between Tenaya Way and Decatur Boulevard.

The project widened CC 215 to four lanes, built two new interchanges at Jones and Decatur Boulevards and a new bridge to carry Bradley Road over the freeway.

Additionally, an expanded bridge over Montecito Parkway was also completed in anticipation of the widening of the beltway between Durango Drive and Tenaya Way as part of the construction of the Centennial Bowl interchange.
