Two crashes on icy I-44 shut down westbound traffic for more than an hour Wednesday morning.
One of those wrecks happened just after 10 a.m. on the interstate just past the West Bypass exit in Springfield (75.2 mile marker).
The crash shut down all westbound lanes, with backups at least a mile.
Those lanes were re-opened by 11:15 a.m., although a stalled vehicle in that same area may cause slowdowns.
In the Joplin area, a wreck closed westbound traffic at the Range Line Road exit (8.6 mile marker), with backups about a mile. By 11:00 a.m., the interstate had re-opened.
The National Weather Service says as of 10:00 a.m., sub-freezing road temperatures exist along and north of a line from Anderson to Cassville, Highlandville, Ava, Houston and Salem.
MoDOT says crews are treating those roadways.
