America Center, 1988, 55 West on the Esplanade, 2009, Solaire at the Plaza, 2006, One Eleven Building, 2009, SunTrust Center at Church Street Station, Under Construction, 326 ft (100 m) Citi Tower, 2017, Modera Central, 2018, 260 ft (80m) Citrus Center, 1971, Premier Trade Plaza Orlando, 2006, CNL Center City Commons, 1999, Towers built in downtown Orlando have not exceeded since the completion of the Suntrust Center in 1988. There has never been an "official" reason why, but local architects speculate it is due to the Orlando Executive Airport location just east of downtown. The airport's flight path is over the city center, thus the Federal Aviation Administration has imposed height restrictions. Transportation Downtown Orlando is served by three main arteries, two limited access highways, several secondaries, and many byways. Limited Access Spessard L. Holland East-West Expressway (SR 408) Interstate 4 (SR 400) Arterials Orange Avenue (SR 527 - One Way SB) Rosalind Avenue (SR 527 - One Way NB) Colonial Drive (US 17/92-SR 50 - E/W) Orange Blossom Trail (US 441 - N/S) Secondaries South Street (SR 15 - WB Along SR 408) Anderson Street (SR 15 - EB Along SR 408) Hughey Avenue (SB Along I-4) Garland Avenue (NB Along I-4) Robinson Avenue (E/W Along North Side of Lake Eola) Central Avenue (E/W) Along South Side of Lake Eola) Public transportation Bus The Central Florida Regional Transportation Authority (CFRTA), better known as Lynx, operates the regional bus service with its central station and offices located at 455 N Garland Avenue. Lynx Operates a zero-fare bus route called Lymmo (Link 31) along a completely separate and dedicated right-of-way. Because this bus system runs on its own right-of-way and controls the traffic signaling, in most cases it is superior to automobile travel within the downtown area. Lymmo service also runs along the Orange Avenue corridor, north to Florida Hospital and south to Michigan Avenue. There is also an east/west connection from the Citrus Bowl to South Eola. Rail Downtown is served by an Amtrak station about a mile south of the central business district. The Silver Meteor and Silver Star lines provide train service to New York City, Miami and Tampa. Construction began in 2012 on SunRail, a north–south commuter rail that will run mostly along existing CSX/Amtrak rails. Launched in 2014, it provides service between the northern suburb of DeLand to the southern suburb of Poinciana. A large transfer
