A major crash on the far north side shut down both sides of Loop 1604 at Bulverde Wednesday morning.
Accident investigators say three vehicles including an 18-wheeler were involved in that crash, which happened around 9 a.m.
There were reports of several minor injuries and the driver of the big rig was taken by medical helicopter to an area hospital in stable condition.
By noon, the eastbound lanes of 1604 had reopened to traffic, but the westbound lanes remained closed as crews continued to clean up the wreck.
KSAT has a crew at the scene and will have more information as soon as it becomes available.
