Road crews begin work Monday on Lake Shore Drive to make it easier for cars to avoid getting stuck during a blizzard. City workers will begin building two turnaround points after rush hour.

Both escape routes are on the near North Side - one will be at Armitage; the other at Schiller. Chicago Department of Transportation officials say those spots were chosen because they’re prone to snow drifts.

They will create turnaround access to north and southbound lanes during emergency situations, like last February’s 20 inches of snow blizzard. Drivers and vehicles were stranded on the Drive for hours.

Three lanes in both directions will remain open around the construction zone. The new turnarounds are expected to be completed by late November.
