New York State Route 390 (NY 390) is a north–south state highway located along the western edge of the city of Rochester, New York, in the United States. The route, a limited-access northward continuation of Interstate 390 (I-390), extends for from I-490 in Gates to the Lake Ontario State Parkway in Greece, less than from the Lake Ontario shoreline. Between I-490 and NY 104, NY 390 makes up the north–south segment of the northwest quadrant of the Rochester Outer Loop, a series of expressways encircling Rochester. At NY 104, the Outer Loop departs NY 390 and follows NY 104 east into the city. The freeway was constructed in stages from the 1960s to the 1980s, with the first segment—between I-490 and NY 31—opening to traffic . At the time, it was part of NY 47, which followed the completed portions of the Outer Loop from Gates to Irondequoit. An extension of the freeway north to U.S. Route 104 (US 104; now NY 104) was opened to traffic in the early 1970s. NY 47 was eliminated in 1980, giving way to NY 390 from I-490 to NY 104. NY 390 was extended to its current length in the early 1980s. ==Route description== NY 390 begins at the point where I-390 northbound crosses over I-490 eastbound in the center of a complex interchange between the two in Gates. Due to the setup of the junction, the northbound and southbound roadways, both two lanes wide, are initially set about apart. The highway heads through the remainder of the exit, passing over the left exit ramp from I-490 west to I-390 south heading northbound and under the ramp linking I-490 east to NY 390 north southbound and crossing over I-490 westbound. North of the junction, the median narrows to a more standard width as NY 390 widens to six lanes and connects to NY 31 (Lyell Avenue). The expressway proceeds north through neighborhoods equally residential and industrial, crossing over both the former right-of-way of the CSX Transportation-owned Falls Road Secondary Track and the Erie Canal prior to meeting Lexington Avenue via a modified trumpet interchange. From Lexington Avenue, where NY 390 passes into the town of Greece, north to NY 104, NY 390 runs parallel to the western edge of Eastman Business Park, the large production and distribution complex owned and maintained by Eastman Kodak. Midway between the Lexington Avenue and West Ridge Road exits, NY 390 encounters Ridgeway Avenue via a partial diamond interchange.〔 Just north of Ridgeway Avenue, the expressway crosses a small, narrow strip of land that lies within the Rochester city limits, a carryover from when the Erie Canal occupied this tract and entered the city decades before. North of the strip, NY 390 curves to the northeast, passing along the west side of the industrial park and the eastern edge of a residential yet wooded area to reach NY 104. Heading northbound, the is split into two halves, with exit 24A connecting to NY 104 east and exit 24B linking to NY 104 west.〔 Past NY 104, the roadway surface shifts from pavement to concrete as the freeway heads generally northward through primarily residential neighborhoods. The next exit, with Vintage Lane to the north-northeast of NY 104, is the highway's last as a six-lane freeway. Here, it narrows to four lanes—two in both directions—before continuing onward to meet NY 18 (Latta Road) at a conventional diamond interchange. At this point, all commercial vehicles are forced to exit NY 390 due to a similar restriction on the Lake Ontario State Parkway to the north. Outside of a small pocket of development near Greece Arcadia High and Middle Schools, the remainder of the freeway crosses open, sparsely developed areas of Greece. NY 390 curves to the northeast for its final before ending at a trumpet interchange with the parkway from the shore of Lake Ontario.〔 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 York State Route 390」の詳細全文を読む スポンサード リンク
