NORTH PLATTE, Neb. -- After a series of highways were closed or deemed impassable on Tuesday, most of the state is now fully opened.

While many of Nebraska's roadways remain under less-than-ideal driving conditions, the lone stretches of highway that were deemed impassable by late Tuesday afternoon were a brief stretch of Highway 83 north of Thedford and Highway 281 north of O'Neill.

Whiteout conditions are causing the bulk of the issues north of O'Neill near the South Dakota border.

Travel is not advised on the stretches of roadway currently deemed impassable.
