King's Highway 410, also known as Highway 410 and colloquially as the four-ten, is a 400-series highway in the Canadian province of Ontario that connects Highways 401 and 403 to Brampton. North of Brampton, the freeway connects to Highway 10, which continues north through Caledon as a four lane arterial road. The route is patrolled by the Ontario Provincial Police and has a speed limit of . Highway 410 was built along the alignment of Heart Lake Road south of Bovaird Drive, while north of Bovaird Drive it was built along a new alignment. The highway was designated in 1978 between Highway 401 and Bovaird Drive (later Highway 7), though it was only two lanes wide and did not feature any interchanges. It was widened throughout the 1980s and completed as a freeway in 1991. In 2003, construction began on a northward extension of the freeway that was completed in November 2009. A notable feature of Highway 410 is the four-level interchange with Highways 401 and 403 which includes a large flyover ramp from Highway 401 eastbound to Highway 410 northbound, constructed in 1990. The majority of the freeway features a grass median as opposed to an Ontario Tall Wall like neighbouring freeways. == Route description == Highway 410 is a commuter freeway and a bypass of Brampton, acting as the southward continuation of Highway 10. The highway is also a continuation of Highway 403 (eastern segment) from the south, which ends at the Queen Elizabeth Way. The freeway begins as several ramps converge from Highway 401 north of the large interchange. Maintaining a straight north-westward course, it passes beneath Courtney Park Drive and Derry Road, with a slight jog to the right between the two underpasses. The freeway then intersects Highway 407 as it crosses into Brampton and passes beneath an electrical corridor. Veering to the right once again, the freeway enters a second industrialized area and returns to its northwest–southeast orientation. It passes beneath Steeles Avenue East and later Queen Street East, the former Highway 7, now Peel Regional Road 107. Until it was decommissioned across the Greater Toronto Area, Highway 7 was concurrent between Queen Street East and Bovaird Drive. Passing north of Queen Street, the highway exits the industrial area and enters residential subdivisions.〔 Throughout this section, Highway 410 is located within a cutting below grade. It passes beneath several roads until Bovaird Drive East. The more recently completed extension begins at this point,〔 as Highway 410 passes to the west of Trinity Common and diverges from its straight path into greenspace and alongside the Heart Lake Conservation Area. As it passes beneath Mayfield Road, the highway makes a sharp turn to the west and descends through the Etobicoke Creek valley. After rising back to level ground, it curves north, passing beneath Valleywood Drive. The central concrete median and high-mast lighting end as the freeway becomes Highway 10, which continues north as a four-lane undivided road to Orangeville, Shelburne and eventually Owen Sound. 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「Ontario Highway 410」の詳細全文を読む スポンサード リンク
