HOUSTON, Texas (KTRK) -- Traffic is slow-moving across the Houston area on Thursday as cars return to the roadways after Houston's historic winter storm.

There is still some ice on the roadways, especially on overpasses and bridges, which is dangerous for drivers.

Multiple westbound lanes of the SH-99 Grand Parkway at the Hardy Toll Road were closed due to a multi-vehicle crash.

According to Houston Transtar, the crash was verified at 6:04 a.m. Thursday

There were also major delays on the South Sam Houston Tollway northbound at SH-288. Skyeye flew over the scene, where traffic was at a standstill around 6:30 a.m.

Drivers can take Almeda or Scott as an alternate route.

Meanwhile, multiple lanes of SH-146 at Wharton Wheams Road on Houston's southeast side were closed due to another multi-vehicle crash.

Traffic has been backed up since about 5 a.m.
