Hamilton, IL – The Keokuk-Hamilton Bridge is one of the most important pieces of infrastructure in the Tri-State Region. That point was emphasized during the Floods of 1993 and 2008.
The Illinois approach to the bridge was flooded during those historic events.
In 1993, people had to use the dam to go back and forth between Illinois and Iowa before Highway 136 could be elevated.
In 2008, more than 25,000 tons of rock was brought in to build up of the highway before the water overtook the approach.
The Illinois Department of Transportation is looking for a permanent solution in case another 500-year flood takes place.
Engineer Roger Driskell says IDOT has started the first phase of the Highway 136 project. He says that includes a conceptual plan and an environmental study.
Driskell says public input and ideas are being sought to identify possible risks or alternate plans to elevating the highway. That could include a retaining wall or altering nearby streams.
A key factor in the discussion is the railroad line that intersects Highway 136.
Driskell says there is no timeline in place for this first phase of the project. He says the next phases would be design and construction, which could take place when money is available.
IDOT held a informational meeting about the project on Thursday, January 6. Dozens of people from Illinois and Iowa turned out to gather information and provide input.
Driskell says a citizens committee will eventually be formed to provide additional input as the project moves forward.
