DENVER (AP) — Interstate 70 is back open, after near-zero visibility forced officials to close all 160 miles of the westbound lanes between the Kansas state line and metro Denver and a 70-mile stretch of eastbound lanes from metro Denver to the plains town of Limon yesterday.

The most powerful storm of the winter season pounded Colorado with up to 6 feet of snow in the Rocky Mountain foothills and forced the cancellation of more than 600 flights in Denver yesterday before heading east toward the central plains today.

The airport wasn’t reporting any cancellations today.
