The I-4/Selmon Expressway Connector (also known as the Crosstown Connector) is a toll road that carries traffic between Interstate 4, the Selmon Expressway (SR 618), and the Port of Tampa east of Ybor City in the city of Tampa, Florida. It primarily comprises four parallel one-way roadways west of 31st Street, continuously elevated over local streets, railroads, and vacant land, with a SunPass/toll-by-plate electronic toll gantry spanning the entire structure near the southern end. All movements were opened to traffic on January 6, 2014, but the direct connections to the Port of Tampa are open only to trucks. The connector project is maintained by the Florida Department of Transportation (FDOT),〔Bay News 9, (Better signage needed on Selmon connector ramps? ), February 10, 2014〕 and was constructed by FDOT in coordination with Florida's Turnpike Enterprise (FTE) and the Tampa-Hillsborough Expressway Authority (THEA). Construction began in March 2010 and was completed in January 2014.〔(【引用サイトリンク】url=http://www.mytbi.com/projects/projectinfo.asp?projectID=175&RoadID=3 )〕 The project was one of the largest single recipients of the 2009 Federal Stimulus funding grants.〔(【引用サイトリンク】url=http://www.tampabay.com/news/politics/state/connector-from-lee-roy-selmon-expressway-to-i-4-on-stimulus-list/989396/ )〕 The highway currently has no signed or unsigned state road number. ==Route description== To minimize dangerous weaving patterns and major bottlenecks, traffic utilizing the I-4/Selmon Expressway Connector between I-4 and eastbound Selmon Expressway to/from Brandon is physically separated from traffic utilizing the connector to get to/from Downtown Tampa via I-4 westbound. The entire tollway is elevated. Traffic travelling along eastbound I-4 from I-275 is able to transition onto the eastbound Selmon going to Brandon with access to 50th St being maintained. Eastbound Selmon commuters coming from South Tampa can connect to eastbound I-4 to travel to I-75 North, as well as Lakeland, Orlando, and other points northeastward. For westbound traffic, access to the westbound Selmon, as well as access to 22nd/21st Streets, are provided. Commuters wishing to travel to I-275, Temple Terrace, and Tampa International Airport can access westbound I-4 via the westbound Selmon. Commuters wishing to avoid the gridlock at Malfunction Junction can use the Connector as an alternate route towards St. Petersburg. Cargo traffic to the Port of Tampa (now known as the Port of Tampa Bay) is heavily recommended to use the "Truck Only" lanes of the Connector, as they safely channel truck cargo traffic to and from the Port without burdening Ybor City. Access to the cargo lanes are provided from both directions of I-4. The Port entry ramp disperses at 20th St, just south of Durham St, and likewise, trucks exiting the port can access either direction of I-4 via the slip ramp from 22nd St, just north of Durham St. Because the Selmon's Reversible Express Lanes (or REL) was specifically designed for traffic traveling between Brandon and Downtown Tampa, no access is available from the REL to I-4. Commuters wishing to use the Connector have to use the ground-level "Local Lanes" of the Selmon. Stub ramps were built at the northern ends of the Connector to allow for additional access points to I-4 should traffic conditions warrant. The northern interchange can be easily reconfigured to allow for access onto "Local Lanes" of I-4, as well as planned Managed Lanes (or "Express Lanes") as part of the (Tampa Bay Express ) project. 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「I-4/Selmon Expressway Connector」の詳細全文を読む スポンサード リンク
