An artist rendering for the new Interstate 35W bridgeproject in Minneapolis is displayed at a press conference Monday, Oct. 8, 2007 in St. Paul. Minnesota. The below drawing shows two options for the design of the piers.

The simple concrete bridge design was made public Monday by the Minnesota Department of Transportation and the companies it hired to build the replacement bridge, which is expected to open by the end of next year.

The new bridge combines twin, five-lane spans and will include highly durable concrete, built-in sensors for monitoring its structural integrity and multiple backup systems that were absent in the collapsed steel bridge. It also will be built to accommodate a light rail transit line in the future and a possible suspension bridge underneath for pedestrian traffic. The plan also calls for parks with observation decks below the bridge.

Flatiron and Manson Construction Co., will build it. The contract requires completion by Christmas Eve 2008, although the builders can earn multimillion-dollar bonuses for finishing sooner. [Quoted from KansasCity]
