This article highlights 10 local transportation-engineering innovations in Las Vegas, Nevada. The Las Vegas Area Computer Traffic System (LVACTS) has undergone a significant transformation in preparation for 21st century traffic control. The Tropicana Avenue and Las Vegas Boulevard intersection is a must see for any transportation engineer or planner with its opposing triple left turns and overhead pedestrian walkways. Road and highway construction projects include the Las Vegas Beltway; the Interstate-15 (I-15) at U.S. 95 Downtown Interchange ("Spaghetti Bowl"); widening U.S. 95 between I-15 and Rainbow Boulevard; pedestrian grade-separation bridges over the Strip at several locations; arterial bridges over I-15 at the quarter-section arterials of Hacienda, Twain, and Harmon; and widening of I-15. Other points of interest worth noting include casino access planning and design, McCarran International Airport's new unit terminal, the successful Citizens Area Transit (CAT) public transit system, a gaggle of automated people movers, Las Vegas's neighborhood traffic management program, and precast segmental posttensioned bridge construction using a Norwegian custom-built gantry crane. A brief description is also provided of the Traffic Bowl, a quiz-show-style competition on transportation engineering to take place during the Institute of Transportation Engineers' (ITE) 69th annual meeting that pits teams of ITE members against each other.
