The Lee Roy Selmon Expressway originated from an expressway system called the Tampa Bay Crosstown Expressway System. The expressways were planned during the 1950s, '60s and '70s. However, the system fizzled out due to financial burdens, land acquisition issues, and community concerns. ==The South Crosstown Expressway== What is known today as the Lee Roy Selmon Expressway was originally called the "South Crosstown Expressway", and was originally designated as State Road 449. The original name can be seen on many older maps and atlases. Original designs had the expressway north of its present route, beginning around Bay-to-Bay Blvd and following a CSX rail line to Cass St, and then cutting through central downtown, and ending around 50th St. In addition, there were plans to connect what is today Ashley Dr to the expressway. However, this plan was changed, most likely due to the development in downtown. Instead, the route was shifted south, taking the expressway through southern downtown. Construction commenced on the South Crosstown Expressway in 1974, beginning around Gandy Blvd at Dale Mabry Hwy and traveling along a CSX rail corridor through Palma Ceia. The route then made an eastward turn at Platt St/Willow Ave as it snaked its way through historic Hyde Park. Construction ended with a 3/4 mile-long, six-lane viaduct that spanned the Hillsborough River in the southern portion of downtown and stopped at Florida Ave (Exit 6A). Stub ramps at the expressway's east end were built for easy extension of the route. The initial six miles (10 km) of the South Crosstown Expressway opened in 1976. Construction commenced on an extension in 1979 due to the immense population growth in Brandon and the heavily congested State Road 60 (Adamo Drive). The extension opened in 1981 and extended the downtown viaduct through the southern vicinity of Ybor City. The route continued through the Palm River area, closely parallel to State Road 60 for much of the extension's route, and terminated at a partial interchange with Faulkenburg Rd (Exit 14). Construction of I-75 from Lutz to Hialeah in the late 1980s connected a trumpet interchange with the expressway. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tampa Bay Crosstown Expressway System」の詳細全文を読む スポンサード リンク
