All lanes of southbound Interstate 75 are reopened after a tractor-trailer crash that blocked at least one lane most of the day, Lexington police spokeswoman Sherelle Roberts said.

Traffic was congested but moving steadily when the road reopened about 2:15 p.m.

The injury wreck closed all of I-75 southbound at the northern I-64 split before 9 a.m. Monday. One lane was opened about two hours later, but traffic continued to be congested for hours, Lexington traffic engineer Chris Quan said.

A large amount of fuel was spilled in the road. The right lane of the ramp from southbound I-75 to eastbound I-64 remained closed while hazardous-materials and environmental crews worked to clean it up.

Almost as soon as that was clear, another crash on the ramp caused the left lane to be closed briefly until a damaged car could be removed.

Several other injury and non-injury wrecks were reported in northbound and southbound lanes near the split through the course of the day.
