State Route 385 (SR 385) is the designation for three separate segments of state highway in the Memphis Metropolitan Area in Shelby and Fayette counties in West Tennessee, forming a semicircle around and through the Memphis suburbs. Clockwise, from the north, they are: * Paul W. Barret Parkway, from U.S. Route 51 (US 51) in Millington to US 70 in Arlington. * Winfield Dunn Parkway, from US 70 in Arlington south to Interstate 269 (I-269) in Collierville. * Bill Morris Parkway (formerly known as Nonconnah Parkway), from I-269 west to I-240 in East Memphis. As of November 2013, all segments of the originally planned portion of SR 385 have been opened to traffic. Paul Barret Parkway and Bill Morris Parkway were completed in 2007. Construction on the missing connecting segment of Winfield Dunn Parkway began around 2009, with it opening to traffic on November 22, 2013 at 4:00 PM. The route is constructed to Interstate-compatible freeway standards with full control of access throughout. The southern portion of the loop is notable for its almost-exclusive use of single-point urban interchanges. The Barret and Dunn parkways are planned to become part of the I-269 Memphis Outer Loop within the next decade, forming the northern half of the semi-circular loop; the southern half is currently designated as part of Mississippi Highway 304. At the present time, the route is not signed as I-269, but signs have been installed in Tennessee that read "Future I-269 Corridor." When the Bill Morris segment between US 72 and SR 57 was constructed, a partial interchange was built between the two roads. A flyover ramp was built for the eastbound lanes spanning an empty field for what was to become the through lanes for I-269 and ghost ramps were built for both directions. Construction on completing this interchange started in 2013 when the I-269 segment between here and the TN/MS line began construction. When done, Bill Morris Parkway will "terminate" at what will be I-269 (although existing lane configurations will more than likely remain). The Winfield Dunn Parkway portion was initially referred to as the Collierville Arlington Parkway in media reports about its construction. however, the portion was officially named after Winfield Dunn in April 2012. Dunn is a former dentist from Memphis who became governor in 1970. The portion of SR 385 between US 51 and SR 204, and the portion between I-240 and Ridgeway Road, was signed as a state secondary route when initially constructed; as of 2007, some now-incorrect signs remain along some sections of the highway and along Ridgeway Road. ==History== 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「Tennessee State Route 385」の詳細全文を読む スポンサード リンク
