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.) Photo taken by J.R. Manning in July 2007 |

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. Photo taken by J.R. Manning in July 2007 |
