The Deuce

Before the Deuce's debut, the Las Vegas Strip corridor was served by route 301, which ran between Downtown Las Vegas and the former Vacation Village resort. It was also accompanied by its express counterpart, route 302. (When the transit authority was branded as Citizens Area Transit (or CAT), it categorized routes serving the Strip under the 300's.)

In March 2010 a new bus rapid transit line connecting the Strip to downtown Las Vegas and Town Square and the South Strip Transfer Terminal became operational. This new 11 mile service was called ACE Gold Line and is similar to the Metropolitan Area Express BRT Line which had been operating since June 30, 2004. Due to a lawsuit by Ace Cab, the line was rebranded as the Gold Line. On November 7, 2010, it was rebranded to be known as the Strip and Downtown Express (SDX). The SDX bus was discontinued due to impacts to revenue from the COVID-19 pandemic.

Previously, RTC planned to shorten The Deuce on the Strip from the current 9.3 miles to just the 5 miles of the Strip from Mandalay Bay Casino to Palace Station on Sahara Avenue. This would have been the first time in 45 years (including Las Vegas Transit System) that the main Strip corridor route had undergone a major route change and be shortened. However, the first week of the service change, the northern portion of the route was reinstated with buses continuing to serve the Downtown Transportation Center, while still ending at Mandalay Bay the hours that the SDX operated. When the SDX was cancelled, buses returned to the Deuce's original route, from South Strip Transit Terminal to Fremont Street.

As of 2020, the fare for the Las Vegas Strip is $6 for a two-hour pass, $8 for a 24-hour pass, or $20 for a 72-hour pass.

The route operates using Alexander Dennis Enviro500 vehicles built by the British manufacturer Alexander Dennis. They each seat 27 people on the lower deck, 53 on the upper deck, and are 42 feet long. RTC Transit is one of six transit agencies that operate double-decker buses in the United States.

In 2006, the RTC announced that they purchased 40 more double-deckers that arrived in Spring 2007, and another 40 that arrived in 2008. These new vehicles replaced the original 50 that have been serving the Strip. The original vehicles were reassigned to local routes (height permitting). These new Deuces are special in that they have 2 staircases, one in the current position, and a second one in the back. They are also 2 feet longer than the present double deckers, and have earned the nickname "Superdeuce."

Since January 2008, 80 new double deckers have arrived with half of that order featuring the reconfigured 42 ft, double staircase bus. The double staircase buses are assigned mostly to The Strip, while some, as well as all of the 40 ft double deckers are assigned to local routes. Although rare, some of the 40 ft vehicles will find their way onto The Strip route as a last resort.

In 2020, the RTC made a purchase of 40 more double deckers that has slowly replaced the 80 older double deckers over time, with the last of the double deckers from 2008 and 2007 retiring in 2024.
