:''Eastern Expressway redirects here, for the highway in Mumbai, see Eastern Express Highway'' Interstate 490 (I-490) is an auxiliary Interstate Highway that serves the city of Rochester, New York, in the United States. It acts as a northerly alternate route to the New York State Thruway (I-90), leaving it at exit 47 in the town of Le Roy and rejoining the highway at exit 45 in the town of Victor to the east. I-490 connects with I-390 and New York State Route 390 (NY 390) on the western side of Rochester and I-590 and NY 590 on the east side of the city at an interchange known as the Can of Worms. The highway comprises the southernmost portion of the Inner Loop, a beltway around the interior of Rochester. Outside of the city, I-490 serves several suburban villages, such as Churchville and Pittsford. The eastern half of the freeway, named the Eastern Expressway, was built in stages from the 1950s to the 1970s as a connector between the Inner Loop and the Thruway. From downtown Rochester to the Can of Worms, it follows the former right-of-way of the Rochester Subway and, before it, the Erie Canal. The section west of the Inner Loop was mostly built during the 1960s and completed in the early 1970s. During the 1950s and early 1960s, the portion of the Eastern Expressway from what is now the Can of Worms east to Bushnell's Basin was originally designated as part of NY 96. That route was moved back onto its parallel surface routing when I-490 was assigned to the entirety of the then-proposed Le Roy–Victor freeway. ==Route description== Heading northeast from exit 47 of the New York State Thruway (I-90), I-490 passes through rural portions of eastern Genesee County and western Monroe County, skirting the villages of Bergen and Churchville. Gradually, the expressway takes a more easterly alignment near exit 3 before returning to the northeast at exit 4. At exit 6, I-490 intersects the Airport Expressway (NY 204). Past this interchange, I-490 heads due north, connecting to NY 33 and NY 531 before returning east. Prior to crossing the Erie Canal, I-490 meets NY 390 and I-390. Beyond the junction lies the canal and the city of Rochester. Between the Mount Read Boulevard interchange at exit 10 and the Genesee River, I-490 is referred to as the "Western Gateway". This section, which saw major decorative and structural improvements in the late 2000s, travels due east through heavily residential neighborhoods before turning to the southeast near Frontier Field and a junction with the Inner Loop at exit 13. Just west of this point, I-490 passes over West Broad Street (NY 31) and close to the former Rochester terminal of the Buffalo, Rochester, and Pittsburgh Railway, which now houses Nick Tahou Hots.〔 I-490 now becomes part of the Inner Loop as it passes just south of the city center and heads toward the Genesee River. I-490 crosses both the river and NY 383 by way of the Frederick Douglass–Susan B. Anthony Memorial Bridge and connects to NY 15 before leaving the Inner Loop〔 and turning south and east to follow the former pathway of the Erie Canal and the Rochester Subway through the east side of the city. Along this stretch, I-490 connects to NY 31 (now part of Monroe Avenue) and passes north of Cobbs Hill Reservoir and the surrounding Cobbs Hill Park.〔 I-490 continues to run in the former bed until exit 21,〔 where I-490 connects to NY 590 and I-590 at an interchange known locally as the Can of Worms.〔 At this point, the former Erie Canal route (now part of I-590) curves southward〔 while I-490 continues eastward into the eastern suburbs of Rochester. Between exits 21 and 24, I-490 parallels the CSX Transportation-owned Rochester Subdivision rail line, intersecting NY 441, a four-lane divided highway in the process. South of exit 25, I-490 traverses the southeastern suburbs of Rochester, passing close to East Rochester, Pittsford and Bushnell's Basin and closely paralleling NY 96 on its way toward the Ontario County line. The freeway meets NY 96 twice in Perinton and a third time in the Ontario County town of Victor, where I-490 passes along the western fringe of Eastview Mall. I-490 ends a short distance southeast of the third NY 96 interchange at Thruway exit 45.〔 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「Interstate 490 (New York)」の詳細全文を読む スポンサード リンク
