The July 20 reopening of the Interstate 65/I-70 interchange in Indianapolis has earned Chicago-based Walsh Construction at least $3 million in incentives. In its $33-million contract, Walsh reduced a planned 85-day complete shutdown by 30 days and rehabilitated 33 bridge decks and 35 lane-miles of pavement. The Indiana Dept. of Transportation sees the total shutdown method for repairs, dubbed "Hyperfix," as "a useful tool on certain projects," says Bryan Nicol, INDOT commissioner. In addition to increased safety, "when you have the whole road to yourselves, you have more options," says Walsh senior project manager Brad Koester. Walsh would have had to pay $100,000 a day for every day beyond the scheduled deadline.
