Mid-morning on Wednesday, more drivers ventured back out to the roads. In the case of the Southwest Freeway, that may have been too soon.
Icy patches remained, mostly at overpasses and near freeway curves, along Highway 59. Police blocked some areas, and as the traffic backup worsened, some drivers tried to get out of the gridlock by turning around and driving the wrong way down the Chimney Rock exit ramp, headed for the feeder roads. City of Houston Mobility Response Team members arrived on the scene to clear the backup shortly after 11 a.m.
