Harris County Precinct 8 deputies, Baytown police and state police animal control officers handled the scene. While law enforcement had the animal's best interests at heart, the gator wasn't easily convinced, initially backing away from officials.
WATCH: What you should do if you spot a gator on the freeway
Once tethered by a rope, the alligator thrashed and rolled. It took about five officers to bring the animal under control, duct taped and loaded in the bed of a pickup truck.
Finally secured, the roughly 8-foot-long alligator was transported just a short distance, to safety just beneath the bridge. There, the restraints were removed and the animal released on the grassy bank of a small tributary connecting with the ship channel.
The day's adventure over, the gator quickly waded through the shallows, and swam away to deeper waters.
La Porte police say it's not uncommon to spot alligators on the road. However, a report of an animal on this bridge hasn't happened before in recent memory.
Earlier on Wednesday, a cow got loose from a pasture and caused delays on I-10 near the East Beltway. It took the Harris County Sheriff's Office livestock unit about 20 minutes to corral the cow over to the nearby cemetery, where it rested on the road for a while until its owner could claim it and remove it to safety.
