Mehaffey Bridge Complete

[UPDATE:] As of October 21st, 2015, Mehaffey Bridge is fully open to the public! The unique design and construction of the bridge has also caught the eyes of statewide engineering and public works societies, winning Iowa’s chapter of the American Society of Civil Engineers (ASCE) award for “Outstanding Civil Engineering Project” for 2016, and the Iowa’s chapter of American Public Works Association (APWA) award for “Project of the Year” for the 2016 category of transportation projects costing more than $2.5 million.

The new Mehaffey Bridge will replace the aging existing structure with a wider bridge, capable of supporting up to 4 lanes of traffic in the future. To help minimize the inconvenience of construction to the general public, the new bridge was designed such that the majority of the structure could be built around the original bridge without having to shut down the road. The new bridge also features tower piers that suspend floor beams, reducing the required number of piers in the lake to allow for more boat traffic. The suspended features of the new bridge utilize post-tensioning elements to allow for the unique shape. The bridge will require almost 3,000 cubic yards of concrete and over 850,000 pounds of reinforcing steel.
