The Eureka Bridge

According to Gregory Franzwa, historian of the Lincoln Highway Association, this bridge was built in 1913 to replace a "...flimsy pony truss..." that collapsed from spring flood waters. He also says, "The five-arch spandrel fill concrete structure was one of the first designed by the Iowa State Highway Commission. It was built by the Marsh Engineering Co. of Des Moines." (Gregory Franzwa, The Lincoln Highway: Iowa, 1995, Patrice Press.)

The west portal

This bridge is due to undergo massive rebuilding and restructuring - but not replacement. Officials recognize the historical significance of this bridge, which once carried the Lincoln Highway west of Jefferson.

Deck and railings

Plans call for the west railing to be carefully removed and restored. The substructure will be rebuilt and widened to support a new, wider deck. If the railing survives the removal, it will be restored to the new deck.
