Manitoba provincial highways

Provincial Trunk Highways (PTH) 100 and 101 (locally known as the Perimeter Highway) form a beltway around the Canadian city of Winnipeg, Manitoba. The Perimeter is approximately 90 km (56 mi) long. It is an alternate route around Winnipeg for through traffic, as there are no freeways through the city.

The highway was originally built in 1955, following the cancellation of a freeway system to accommodate traffic around Winnipeg to avoid the city centre rush hour traffic. The northeast section was left unbuilt at the time, as PTH 59 had received significant upgrades, making the need for a northeast section less pressing. PTH 59 continued to serve as the de facto northeast leg of the Perimeter until the mid-1990s, when the remaining segments of the highway were completed. The highway now encircles Winnipeg.

Most of the Perimeter is a four-lane divided expressway, with interchanges and at-grade intersections. The only section that remains two-lane is in the vicinity of the PTH 59N interchange. In September 2015 however, construction began on upgrading the current at-grade intersection at PTH 59 with a modified Cloverleaf interchange. Once complete, the remainder of the two-lane Perimeter will be upgraded to divided highway, thus making the entire ring road divided highway. Construction is expected to be complete by 2018.
