Wintry weather caused part of Interstate 680 northbound to close for a time after a three-car crash Sunday evening.

The cars collided on I-680 near the Midlothian ramp in Youngstown around 6:15 p.m. 

Police say two cars slid into each other and then another car hit them afterward.

The northbound Midlothian ramp was blocked off and that area was temporarily reduced to two lanes.

No injuries were reported.
