Cameras mounted on traffic light supports at either end of the Thomas McCall bridge are there to ease your driving experience.

Sean Brown, spokesman for the Pennsylvania Department of Transportation, said that the cameras detect traffic backing up on either end of the bridge and when the traffic is backed up more than three-quarters of the way on the bridge, the camera signals the traffic light to remain green a little longer.

Brown added that the cameras do not record anything.

"Essentially the cameras keep traffic flowing on Route 209 by preventing backups," said Brown. "Sometimes on the weekends the traffic would back up due to higher volumes."

Franklin Township purchased the camera on the Franklin Township side of the bridge, while Lehighton Borough purchased the camera on the Lehighton side. Both municipalities are responsible for the maintenance of their respective camera.
