A crash involving an 18-wheeler has the northbound lanes of I-35 moving very slowly just south of Belton this morning.

The 2 right lanes and the shoulder of I-35 northbound are blocked near Shanklin Road (mile marker 290) and motorists are encouraged to seek alternate routes. Delays are expected for at least the next hour.

TxDot is calling the accident minor but encourages motorists to avoid I-35 northbound in this area if possible.
