State Route 147 (SR 147) is a state highway serving the Las Vegas Valley in southern Nevada. It is signed as Lake Mead Boulevard and runs from Interstate 15 (I-15) and U.S. Route 93 (US 93) in North Las Vegas east to the border of the Lake Mead National Recreation Area. It is not to be confused with Lake Mead Parkway (formerly Lake Mead Drive), which also goes to Lake Mead but mainly runs in southern Las Vegas Valley and carries the designation of State Route 564.
