Several cows escaped onto I-45 in north Harris County on Monday, creating a major traffic jam. The animals got loose after a vehicle transporting livestock broke down near Spring Stuebner Road. One cow was caught on traffic cameras dodging cars and leaping the median before disappearing from view.

Authorities eventually corralled several cows, but the incident caused miles of congestion. Harris County officials confirmed one cow was hit by a vehicle, and a car overturned, though details on the cause were unclear. By 1 p.m., traffic was slowly moving again as crews worked to clear the scene.
