King's Highway 402 is a 400-series highway in the Canadian province of Ontario and a vital trade link with the Midwestern United States, connecting the Blue Water Bridge international crossing near Sarnia to Highway 401 in London. The controlled access freeway is four-laned for nearly its entire length, widening at the approach to the Blue Water Bridge. It originally ended within the Sarnia city limits, merging into Highway 7 near the present Highway 40 interchange. Although it was one of the original 400-series highways, it was not completed until 1982; construction extending it to London began in 1972 and was completed with the final link between Highway 81 and Highway 2. The entire route became a controlled-access highway with the removal of an intersection at Front Street in Sarnia. Highway 402 offers access to Interstate 69 (I-69) and I-94 into Port Huron, Michigan, as well as 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. (Full article...)
