New Circle Road, also known as Kentucky Route 4, is a Kentucky state highway that serves as an inner beltway around Lexington, which is part of the consolidated city-county government with Fayette County. The state designates the start and finish of the road at its interchange with Nicholasville Road on the city's south side. Exit numbering increases as one travels clockwise. Roughly three-fourths of the highway is limited-access, with all movements controlled at 10 interchanges. The remainder is classified as an urban principal arterial highway with a heavy mix of driveway entrances and intersections with one single-point urban interchange at US 60 (Winchester Road) and a diverging diamond interchange at US 68 (Harrodsburg Road). The dividing line between the limited-access segment and the urban arterial highway is US 25 (Richmond and Georgetown Roads) north and east of the city. ==History== New Circle Road, Lexington, was constructed in several segments from 1950 to 1967〔 〕 as a circumferential bypass. It was to be designated Interstate 464, But the designation was removed due to no connection to I-64. The first segment to be built, from KY 922 (Newtown Pike) to US 25 (Richmond Road)/US 421, was constructed by the city of Lexington in 1952 as two-lane connector road. The original section included at-grade intersections at Palumbo Drive, KY 1927 (Liberty Road), KY 57 (Bryan Avenue), Old Paris Pike, US 27/US 68, and at KY 353 (Russell Cave Road), with one interchange at US 60 (Winchester Road). This segment of the road is also known as the Northern Belt Line or the US 25 Bypass. To help finance the construction of the original 1952 portion, driveway access was sold to property owners along the route.〔http://www.newcircleroad.com/ 〕 At the time of construction, this area was mostly rural and surrounded by horse farms, as Lexington had not yet begun to sprawl out that far. After the opening, this section experienced rapid growth and the need to widen it to four lanes from two became evident. In 1958, maintenance was taken over by the state and construction began on the widening to four lanes as it became US 25 Bypass.〔 In 1966, a study began on more improvements to the original stretch of New Circle Road due to "extremely congested conditions." One of the improvements suggested as another bypass east of New Circle but was ruled out as being "too expensive and disruptive." As an interim solution, frontage roads were constructed along a few portions of New Circle, and longer turning lanes were constructed. The remainder of the highway around Lexington was constructed to near-urban freeway standards with controlled access. Construction of interchanges at US 25 (Richmond Road)/US 421, KY 1974 (Tates Creek Road), US 27 (Nicholasville Road), US 68 (Harrodsburg Road), US 60 (Versailles Road), KY 1681 (Old Frankfort Pike), US 421 (Leestown Road), US 25 (Georgetown Road) and at KY 922 (Newtown Pike). The interchange with Alumni Drive was constructed in late 1984 at a cost of $2 million with the extension of what was then Mount Tabor Road southeastward towards Man o' War Boulevard. 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「New Circle Road」の詳細全文を読む スポンサード リンク
