The final phase of the 1-20/59 bridge replacement project in Birmingham, Ala., will be rebid after the first round of bids exceeded state DOT estimates by $150 million, officials confirm. Replacing the 40-year-old elevated structures in the city's business district and related road work is seen as the most complicated part of the three-phase, $750-million program, which began in 2015. But of three bids received, Granite Construction Co.'s $507.9-million accepted low bid was well above the range of $292 million to $357 million. The I-59/20 bridges handle 160,000 vehicles daily, double the design capacity. The state has set a March 31 deadline for new bids and will pick a contractor soon after. Work could begin by mid-2018.
