McHENRY – Work will start Monday at the intersection of Routes 120 and 31, though “significant delays” aren’t likely until mid-March, the project manager said.
Signs will go up Friday ahead of temporary signal work beginning Monday, kick-starting an intersection improvement project that is expected to be completed in November, said Todd Destree, the project manager with HR Green.
While the beginning of the work means some temporary lane closures – ones that will shut down lanes during the day but reopen at night – will occur, the more permanent lane closures are expected to begin in mid-March, depending on weather and utility relocation, Destree said.
At that time, the four lanes of traffic will be winnowed down to two, one lane in each direction, which will cause “significant traffic delays,” he said.
Drivers can sign up for project alerts by going to www.mchenry120and31.com, which also hosts more information about the project and avenues to ask questions.
The project includes widening and reconstructing Route 120 and Route 31 in the area surrounding the intersection, according to a news release. Route 31 north of Route 120 will be widened to match the five-lane section north of Washington Street.
The bridge that carries Route 120 over Boone Creek also will be widened, and a new storm sewer and drainage system will be installed, the release said.
New traffic signals designed to provide more efficient travel will be installed at the intersections of Routes 120 and 31, Route 120 and Green Street, and Route 31 and Pearl Street, the release said.
The project is expected to cost more than $7 million with about $4.7 million covered by the federal government, $2 million by the state of Illinois and half a million by the city of McHenry.
