The pricetag for the new Interstate 74 bridge and corridor improvements may escalate to $1.4 billion -- more than double the projected cost in 2004 -- before the work is completed.
During the presentation to the Bettendorf City Council last week, Iowa Department of Transportation (IDOT) officials said the overall bridge/corridor work currently is estimated at $767 million, but by 2015 the cost is expected to increase to $1 billion.
Adding in inflation and a contingency amount for unanticipated cost increases between 2015 and when the work is actually completed, the total price for the bridge and highway upgrades could reach $1.4 billion, the IDOT said.
