A two-block area here was evacuated Tuesday evening after a passer-by reported what he thought was a bomb.

At approximately 5:10 p.m. South Salt Lake police received a call from a man walking by the area saying a bomb was in the parking lot of a shopping center at 3186 S. State, said Sgt. Beau Babka. The alleged bomb was reported to be in a large white drink cooler approximately 15 feet from State Street.Babka said the man was curious about the cooler and decided to check it out. When he opened the lid, he saw a timer and a ticking clock with wires running to two long cylinders, Babka said.

When police and fire crews arrived on the scene, a two-block area was blocked off and rush-hour traffic was rerouted. Bomb technicians were called to the site and a remote control robot was sent in to disengage the suspected bomb, Babka said.

The cooler's contents turned out to be a pair of cement timing cylinders used by Wasatch Constructors for installation of message signs in the area.

Wasatch Constructors spokesman Brian Mauldwin said the company will notifiy police when they use these devices in the future.
