Portions of U.S. 290 were shut down Monday after a truck crash in northwest Houston, snarling traffic for miles.

The two-vehicle wreck happened about 11 a.m. on the inbound Northwest Freeway near Little York, according to Houston TranStar.

No information was available about possible injuries or what caused the crash.

The wreck forced officials to block all eastbound lanes while crews cleared the scene. It was unknown when they would reopen.
