Icy conditions briefly closed the SH 45 tollway in Round Rock this morning. Slick spots started developing around 9 a.m. just as the rush-hour was winding down.
Police say ice caused about a half-dozen wrecks between the Kelly Lane exit and I-35.
The westbound lanes were briefly closed so the wreckage could be removed from the roadway.
Those stuck in the traffic also had to wait until a road crew came by to retreat the area with a de-icing mixture.
The roads are open but it's best to take it slow today.
