Nine I-74 Bridges Will Get New Surfaces

(Dearborn County, Ind.) – The Indiana Department of Transportation is planning to rehabilitate nine bridge decks carrying Interstate 74 over roads, railways, and streams in Dearborn County.

It’s a $563,481 project which was awarded to Ram Construction Services in January. Starting in July, the contractor will make pavement repairs before applying a tough epoxy polymer to the bridge decks.

The I-74 bridges to be improved include five locations:

  • Johnson Fork and Johnson Fork Road—I-74 eastbound and westbound bridges—1.23 miles east of U.S. Highway 52
  • White’s Hill Road—I-74 eastbound and westbound bridges—1.23 miles west of U.S. 52
  • U.S. 52 and the Indiana & Ohio Railroad—I-74 eastbound and westbound bridges—5.44 miles east of S.R. 1
  • a Dearborn County road and the East Fork of Tanners Creek—I-74 eastbound and westbound bridges—2.07 miles west of S.R. 46
  • the I-74 ramp bridging over the Indiana & Ohio Railroad—5.32 miles east of S.R. 1

According to INDOT, Ram’s epoxy polymer overlay is applied in two lifts with a covering of flint rock chips spread across each application.  Polymer seals the bridge decks from moisture intrusion, extending service life.

The flint makes for better surface friction and resists polishing, which will mean more traction for tires and enhanced driver safety.
