SALT LAKE CITY (AP) — The political signs sprouting up across the Salt Lake City area on overpasses, pedestrian bridges and highway boundary fences are technically illegal but the law isn’t really enforced.

Utah Department of Transportation spokesman John Gleason tells the Salt Lake Tribune that it is illegal to place campaign signs in rights of way without approval from the department. He says the department never approves them.

Gleason says the department’s workers have more important things to do than taking down hundreds of illegal signs statewide, but when they do go out and remove some, more tend to show up the next day.

He says the department also takes action on signs that create a hazard such as blocking essential sightlines or threatening to fall into a roadway.
