The state is ready to start rebuilding the intersection of Routes 64 and 47 in Lily Lake, including installing a traffic signal.
Signs were posted this week indicating work will start next week.
Route 64 is closed just east of Route 47. Traffic will be detoured on La Fox Road and on Route 38.
Later this summer, Route 64 will be opened, and Route 47 south of Route 64 will be closed.
Besides the traffic signal, the intersection will get left-turn lanes in all directions. The road will be raised to improve drainage. Drivers have been vexed for years by water that collects in a low spot on Route 64 just east of Route 47.
There will be a new bridge, a new retaining wall, and new and longer culverts installed, according to the Illinois Department of Transportation.
The state shows annual average daily traffic counts of 5,450 vehicles (1,000 trucks) on Route 47 north of Route 64, and 7,150 vehicles (1,050 trucks) south of the intersection; 5,000 vehicles (1,050 trucks) on Route 64 east of the intersection, and 6,250 vehicles (650 trucks) west of Route 47.
The work is expected to be completed no later than Nov. 15. The lead contractor on the $5.1 million project is Curran Contracting Co. of Crystal Lake.
Farther south on Route 47, the state plans to repave the highway from Seavey Road to just north of Welter Road, including adding rumble strips.
