HOUSTON, Texas (KTRK) -- You'll want to avoid the northbound and southbound SH-99 Grand Parkway connector ramps to the I-10 Katy Freeway eastbound for a little while longer.
An overturned 18-wheeler has been blocking the area since about 5:40 a.m. Thursday.
At about 9:30 a.m., TxDOT said in an update that drivers, especially those traveling into Houston from Katy and Cinco Ranch, should expect the cleanup to take another four to five hours.
As an alternate route, drivers can take the SH-99 westbound exit ramp and make a U-turn.
SkyEye video from above the crash showed smoke below the roadway where the 18-wheeler crashed.
