To demolish the existing IA 92 bridge over Mosquito Creek, between the U.S. 275/IA 92 interchange and Harry Langdon Blvd, contractors must use a more sensitive method to remove the concrete. Sensitive measures are needed due to the proximity to the creek, environmental mitigation measures and the need to maintain full access at all times.
Typically, the demolition of existing bridges involves the use of a jackhammer on the bridge decks, while allowing large pieces of concrete to fall below. This method is generally quick and relatively inexpensive.
