King's Highway 402, commonly referred to as Highway 402 and historically as the Blue Water Bridge Approach, is a 400-series highway in the Canadian province of Ontario that connects the Blue Water Bridge international crossing near Sarnia to Highway 401 in London. It is one of two vital trade links between Ontario and the Midwestern United States. The controlled access freeway is four-laned for nearly its entire length, except on the approach to the Blue Water Bridge, where it widens. Although Highway 402 was one of the original 400-series highways when it was designated in 1953, it was not completed until 1982, when the final link between Highway 81 and Highway 2 opened to traffic. The freeway originally did not exit the Sarnia city limits, and merged into Highway 7 near the present Highway 40 interchange. In 1972, construction began to extend Highway 402 between Sarnia and London; this work was carried out over a decade. The removal of an intersection at Front Street in Sarnia made the entire route a controlled-access highway. Motorists crossing into Michigan at the western end have direct access to Interstate 69 (I-69) and Interstate 94 (I-94) into Port Huron; motorists crossing onto the Canadian side from the east end of I-69 and I-94 have access to Toronto via Highway 401, and onwards to Montreal via A-20 in Quebec. The only town along Highway 402 between Sarnia and London is Strathroy. == Route description == The Blue Water Bridge crossing has six lanes of bridge traffic and non-stop freeway access, therefore providing a quicker route than the busier Ambassador Bridge crossing in Windsor, which features over ten traffic lights leading to the bridge. Across the Blue Water Bridge, Highway 402 continues in Michigan as I-69 and I-94.〔 With the exception of the Front Street interchange in Sarnia, which is a hybrid of a diamond and Parclo B-2 interchange, the freeway uses the Parclo A-4 design throughout its length. Although the freeway passes through Sarnia, it is not intended to operate as a commuter highway. The freeway begins on the Canadian side of the Blue Water Bridge, descending over the village of Point Edward. After passing through a customs plaza, it enters Sarnia and travels parallel to and north of Exmouth Street through the city. Near the eastern limits, the freeway curves to the northeast to bypass its original alignment.〔 It crosses the Howard Watson Nature Trail, a mixed-use recreational trail that was converted from a Canadian National Railway (CNR) line in 1988. The highway curves back to its east–west orientation at an interchange with Highway 40.〔 It exits the city as it passes south of Sarnia Chris Hadfield Airport.〔(【引用サイトリンク】 publisher = Sarnia Chris Hadfield Airport )〕 Now parallel and north of London Line, the former route of Highway 7 (the predecessor route between Sarnia and London), the freeway jogs north to travel along the back lot line of farmland fronting London Line and the concession road north of Highway 402. In this manner, the freeway did not divide any farms when it was constructed, instead running between them. It meets Lambton County Road 21 (Oil Heritage Road), the northern terminus of the Oil Heritage Route, north of the town of Wyoming. The county road is also a former southern extension of Highway 21, which itself begins as Forest Line to the east.〔〔 Highway 21 is also known as the Bluewater Route, as most of its length is parallel to the shore of Lake Huron. After passing an interchange with Forest Line, the freeway is crossed by London Line and momentarily diverges from its straight alignment to dip south of Warwick. It continues east through large patches of farmland, then meets with Middlesex County Road 81 (Victoria Street) at an interchange as it passes north of Strathroy.〔〔(【引用サイトリンク】 publisher = Middlesex County )〕 Shortly thereafter it curves to the southeast and zig-zags towards London, bisecting farms and dividing woodlands. The freeway passes to the west of the town of Delaware and curves east. It enters London and meets interchanges with Highway 4 south of Lambeth, as well as with Wonderland Road before merging into Highway 401. Access to westbound and from eastbound Highway 401 is provided via Highway 4.〔 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 402」の詳細全文を読む スポンサード リンク
