I-45 lanes reopen after crash near Conroe

Northbound traffic on Interstate 45 was disrupted for several hours after a UPS big rig reportedly carrying ammunition overturned and caught fire in Montgomery County early Thursday morning.

The crash happened on the northbound freeway at FM 830 near Conroe just after midnight, according to Houston TranStar.

The driver had minor injuries, but his condition was not released.

The UPS truck toppled onto its side, caught fire and apparently lost portions of its load. At least one parcel of ammunition was inside the truck officials said.

The wreck forced officials to close all but one northbound lane near the crash site while emergency crews work to clear the area. The lanes were reopened at about 1:10 p.m.

No other information was immediately available.
