Lettered Metrobus routes primarily serve Miami Beach, a practice inherited from the Miami Beach Railway Company upon its public takeover in 1962. The West Kendall area buses do not use 'X' either and instead are labeled as KAT, standing for Kendall Area Transit, which only includes Route 204 and Route 272. Some routes have branches that carry an 'A' or 'B' suffix while the 'X' suffix denotes an express route, although for the 95X this exists only in print. Routes labeled as MAX, short for Metro Area Express', are limited stop services. Routes that are labeled as 'Connections' are regular service routes introduced during the 2000s that for the most part are either primarily or were formerly operated by minibuses. Most routes are identified by number or letter, however several others, specifically Express, MAX, Shuttle, and Flyer routes have formal names as well. Over 100 Metrobus routes are operated by Miami-Dade Transit with some routes contracted by LSF, serving Miami-Dade County, Florida and connecting with several routes in adjacent counties. The 'S' route from Downtown Miami to Aventura Mall via A1A (the beach) is generally the busiest route and uses many large buses such as this hybrid articulated bus.
