Northbound lanes of Interstate 35 were shut down in north Dallas about noon Wednesday due to a crash involving two semi-trucks.
The highway re-opened by mid-afternoon.
One of the trucks' tanks spilled fuel onto the highway, said Melinda Urbina, sheriff department spokeswoman.
All northbound lanes were closed before Valley View Lane, near LBJ Freeway.
