MAHOMET —The Illinois Department of Transportation confirmed this week that construction will start Monday on the bridge that carries Lake of the Woods Road over Interstate 74 east of Mahomet.
During construction, traffic will be detoured via U.S. 150, Prairieview Road and Tin Cup Road.
The bridge has been down to one lane since August 2011, when IDOT determined that the northbound lane of the bridge wasn't in good enough condition to hold up to traffic, and that the more-than-40-year-old structure needed to be replaced.
IDOT put the $4.3 million project out for bid this summer. The contract was awarded to Stark Excavating.
The bridge will be closed to traffic on Monday, Aug. 12. It will remain closed for the length of the project, which could last as long as a year.
The section of I-74 below the overpass will see nighttime closures while workers dismantle the old bridge and set steel beams for the new structure. During that time, traffic will be detoured via Illinois 47, U.S. 150 and Prairieview Road.
I-74 will also see intermittent lane closures during construction of the new bridge.
At one time, IDOT had discussed straightening out the path of the new bridge; the current structure has a slight curve. But Mahomet public works director Gary LaForge, who attended the pre-construction meeting on Tuesday, said the state has reconsidered those plans, since it would have raised the cost of the project significantly.
The new bridge will also include a separate lane for pedestrians and bicyclists, connecting the path that currently ends at the bridge with the section in Lake of the Woods park.
