Half of interstate bridge closed this year, half next year
HENNEPIN — Work is moving along quickly on the $25 million reconstruction of bridge deck that carries Interstate 180 traffic high above the Illinois River between Putnam County and Bureau County.
But that doesn’t mean the project will be over soon.
Crews have been making repairs on the half-century-old I-180 bridge sporadically for the past several years, and now pretty much all but the supports needs to be rebuilt.
Nate Sell, construction field engineer for IDOT, noted this winter that the project will last three years, though motorists will see the biggest effects in 2020 and 2021.
All four lanes share the supports and piers. This year, the crew is rebuilding the eastbound (south) half, and next year, workers will rebuild the westbound (north) half. A painting project is planned for the third year.
Civil Constructors Inc. of Freeport submitted the lowest of three bids for complete bridge deck replacement, pavement restructuring and replacement of the approach.
