Eight Mile Road Bridge, a short span concrete structure built in 1940, needed to be replaced in Hamilton County, near Cincinnati, Ohio.
In addition to replacing the bridge deck slab, the abutments required rehabilitation to extend the life of the structure. In 2000 and 2001, Hamilton County engineers chose to rehabilitate three bridges on Five Mile Road (Bridges B-0071, B-0087, and B-0171) with Fiber Reinforced Polymer (FRP) bridge decks on pre-cast, pre-stressed concrete beams.
An inspection conducted in July 2008 revealed only minor surface cracking in the decks. The decks were cleaned and sealed. Testing confirmed deck deflection was unaffected and corrosion nonexistent.
