Lake Mead
SR 147 first appears on the official Nevada state highway map with the 1978-79 edition as a semi-circular route. The route followed Lake Mead Boulevard (which was previously unnumbered) eastward from North Las Vegas to North Shore Road in the Lake Mead National Recreation Area; south on North Shore Road (replacing SR 41A) to Lakeshore Road; then west on Lakeshore Road (later Lake Mead Drive, now Lake Mead Parkway), replacing part of SR 41. The terminus was at Lakeshore Road and Boulder Highway (then US 93/US 95, now SR 582). The highway continued west of Boulder Highway as SR 146.
