In Winnipeg the bitterly cold winters are not conducive for road construction. It gets so cold that the ground freezes up to 5-6 feet below the surface. The ground is so frozen equipment cannot penetrate through. And cement cannot be poured in those brutal temps. Therefore, all road and highway construction has to be done during the late spring, summer and early fall.
It creates such chaos that many streets are closed or down to 1 lane. Makes it an obstacle course to get around. Regular 20 minute commutes turn into 50 minute marathons. Such is existence in the Great White North.
