CENTERVILLE — Utah Department of Transportation crews have started the noisy task of pile-driving steel support columns as part of the work on the Parrish Lane bridge in Centerville. The expanded bridge will connect the new Legacy Highway with I-15.

UDOT spokesman Adan Carrillo said most of the work will be done during the day, but since crews must halt the process for passing Union Pacific and UTA FrontRunner trains, some night work will also be needed. Carrillo said crews should be finished driving the pillars in about three weeks.

Centerville agencies have made calls to residents in the area warning of the upcoming noise and Carrillo said the decibel level of the work "isn't much more than the sound of a train passing by."

"The nighttime work will be very sporadic," Carrillo said. "We're encouraging residents to use background noise creators — like fans or low music — to offset the sound of the work."

Carrillo said that free ear plugs are also available to residents at the Centerville and West Bountiful city halls.
