TOPEKA, Kan. (AP) -- The Kansas Department of Transportation says all highways that were closed by snow and ice have reopened.

But a couple of crossings at the Oklahoma border in southwest Kansas remained blocked late Tuesday afternoon while crews in the neighboring state made the roads passable. Those closing affected U.S. 83 and Kansas 23, while U.S. 183 and 283 were open into Oklahoma.

Southbound lanes on several highways connecting southwest Kansas and the Oklahoma Panhandle were shut down Tuesday as heavy snow blanketed the region. KDOT says conditions improved enough Wednesday to allow the roads to reopen.

Sections of other U.S. and state routes in southern and central Kansas that were closed by the snowstorm have also reopened.
