A semi-trailer crash snarled rush hour traffic on the Dan Ryan Expressway Thursday morning. State police say the semi jackknifed in the local lanes of the Ryan near 67th Street just after 5 a.m.

The inbound local lanes were closed for about 2 hours while workers removed the semi and cleaned up a fuel spill.

A cause of the crash remains under investigation.
