State Route 146 is a major east–west route in Southern Nevada. It begins at the Exit 27 interchange on Interstate 15 south of the Las Vegas Strip and ends at the Pecos Road (Exit 6) interchange on Interstate 215 in Henderson. The route is known as Saint Rose Parkway, but was known as Lake Mead Drive prior to 2001.

History

The original segment of SR 146 was known as State Route 41 (Lake Mead Drive) until the early-1980s. Originally, it was a 19 mi (31 km) route that began at the current western terminus at Interstate 15 and crossed Boulder Highway in Henderson before ending at the intersection of North Shore Road near Lake Mead.

Construction of I-215 through southeast Las Vegas and Henderson altered the routing of SR 146. Clark County decided to build I-215 between Mile 6 (St. Rose Parkway/Pecos Road) and Mile 0 (the Interstate 515/U.S. Route 93/U.S. Route 95 interchange) on the SR 146 alignment. Since the Nevada Department of Transportation (NDOT) does not co-sign state routes along Interstate highways, the decision was made in 1999 to officially truncate SR 146 to its current eastern terminus.^[1] The portion of the highway east of I-515/US 93/US95 was recommissioned as State Route 564 (and has since been renamed Lake Mead Parkway). Clark County posted SR 146 signs along the 6-mile (9.7 km) overlapping section of I-215, even though the state highway designation no longer existed in this section when the freeway was completed in 2001. Many SR 146 signs still remain on I-215 as of 2007.
