HOUSTON --An accident involving an 18-wheeler and an SUV blocked all southbound mainlanes of I-45 for more than an hour early Wednesday.

Drivers were forced off the freeway at Tidwell, backing up traffic past Beltway 8-North.

Officials said the female driver of a Chevrolet Tahoe was taken to the hospital with minor injuries. The big rig's driver was not hurt.

The crash was cleared out of the way around 6 a.m., but traffic remained bad in the area through the morning commute.

Conditions were made worse by wet roads.

KHOU11 News Meteorologist Chita Johnson said the rain will clear out briefly later in the morning Wednesday, but another round of rain is expected in the afternoon and evening.
