Nevada State Route 146

Nevada 146 is Saint Rose Parkway, which connects Interstate 15 south of the metropolitan area with Interstate 215. Prior to 2002, Nevada 146 continued east, cosigned with Interstate 215 to connect with Interstate 515. Nevada 146 used to continue along Lake Mead Drive to connect with Lake Mead National Recreation Area, but that segment of Nevada 146 east of Interstate 515 is now Nevada 564. Officially, Nevada 146 ends at Interstate 215, but some shields from when it was cosigned may remain on the concurrent stretch with Interstate 215.

In 1996, Nevada 146 was a much longer route. It extended from Interstate 15 Exit 27 east along Lake Mead Drive to the south boundary of the Lake Mead National Recreational Area via former Nevada 41.

In early 2001, Nevada 146 between Interstate 15 and Interstate 215 was renamed as St. Rose Parkway. In June 2002, with the extension of Interstate 215, Nevada 146 was curtailed to follow only St. Rose Parkway in order to avoid an overlap with Interstate 215, which was partially constructed on top of former Lake Mead Drive. This resulted in a reduction to the total route length to 6.673 miles as of the 2000 Route Log. The former segment of Nevada 146 east of Interstate 515 has been recommissioned as Nevada 564.
