Two miles North of Stratford, Iowa is an area known to local citizens as “Bellville”. This is the location of the former Bell’s Mill, as well as our project. Thus, the project officially known as SBRFM-CO94(42)—5D-94 has become known as “The Bellville Bridge”. The current Bellville Bridge is a 631 foot long steel high truss. Built in 1937, the bridge has provided a crossing of the Des Moines River for many decades. However, routine inspections have shown that the structure is deteriorating and needs to be replaced. We hired a consulting engineering firm to design a new bridge. Their proposal calls for a 652’-6” x 30’-0” six-span pretensioned prestressed concrete beam bridge. A letting for construction bids was held through the Iowa Department of Transportation on November 6, 2001. The winning bid was $1.628 million. Construction is scheduled to begin the week of November 26.
