(KMOV)-- All lanes on southbound 270 are open between I-44 and Gravois.
The Missouri Highway Patrol says the number of calls they received during the last couple days was relatively low considering the conditions, meaning people listened to the warnings, and either slowed down or stayed home.
One accident occurred in the West County area Wednesday morning, but there were no major incidents reported.
The highway patrol says most calls were related to vehicles that slid off the roads.
Speed limits on I-270 were lowered to 40 miles per hour during the morning, and were raised to 45 by the afternoon.
Entrance and exit ramps continue to be a problem in the area.
