Weekend traffic: Road buckling from heat possible; I-94 traffic shifts

Hot, hot, hot. The pavement will sizzle, and that has the Minnesota Department of Transportation warning motorists to look out for buckling roads.

The calendar is light on major traffic-generating events. The heat might keep crowds down at celebrations such as the reopening of the Walker Sculpture Garden, the Northern Spark art festival and Minneapolis Open Streets on 1st and Washington avenues N. downtown. But roads might be crowded near lakes, pools and anyplace cool. If you are on the roads, here is where you might sweat it out in construction zones.
