Electrial issue possible cause for fire in O’Hare walkway famous for bright colored lights

Shortly after 8 a.m., an apparent electrical issue sparked a fire in the pedestrian tunnel between Concourse B and C at O’Hare — the long walkway notable for its bright, colored lights running overhead and on the walls. Fire officials were not sure whether the issue was with one of the escalators descending into the tunnel, or the long moving walkways.
