Nevada Condition Route 146
Condition Route 146 (SR 146) is really a 6.673-mile-lengthy (10.739 km) major east-west condition highway in southeast the U.S. condition of Nevada. It begins in the exit 27 interchange on Interstate 15 (I-15) south from the Vegas Strip and ends in the Pecos Road (exit 6) interchange on I-215 in Henderson. The highway is presently referred to as Saint Rose Parkway, but was referred to as Lake Mead Drive just before 2001.
The initial segment of SR 146 was referred to as Condition Route 41 (Lake Mead Drive) before the early-1980s. Initially, it had been a 19 mi (31 km) route that started in the current western terminus at Interstate 15 and entered Boulder Highway in Henderson before ending in the intersection of Northern Coast Road near Lake Mead.
Construction of I-215 through southeast Vegas and Henderson altered the routing of SR 146. Clark County made the decision to construct I-215 between Mile 6 (St. Rose Parkway/Pecos Road) and Mile (the Interstate 515/U.S. Route 93/U.S. Route 95 interchange) around the SR 146 alignment. Because the Nevada Dot (NDOT) doesn’t co-sign condition routes along Interstate highways, the choice is made in 1999 to formally truncate SR 146 to the current eastern terminus. The area of the highway east of I-515/US 93/US 95 was recommissioned as Condition Route 564 (and it has since been renamed Lake Mead Parkway). Clark County published SR 146 signs across the 6-mile (9.7 km) overlapping portion of I-215, although the condition highway designation no more existed within this section once the freeway was finished in 2001—Many SR 146 signs still continued to be on I-215 in 2007, but have since been removed.
The whole route is within Clark County.
