• FLEMING ROAD: The 2½-mile stretch of road between Route 120 and Country Club Road is closed to thru traffic as work begins to rebuild it.
A posted detour will reroute drivers through Woodstock along Routes 120, 47 and 14.
Work is expected to be finished by the end of July, weather permitting.
• CHARLES MILLER ROAD: River Road driving lanes have been reconfigured to eliminate the northbound left-turn lane for the duration of the first phase of widening the Charles Miller Road bridge and improving the intersection of Miller and River roads.
Work is ongoing to create another two-lane span over the Fox River and widen Miller Road to four lanes with dedicated turn lanes from Route 31 to River Road.
The first phase, which consists primarily of building the new span, will cost about $12 million and is anticipated to be finished by the end of October, weather permitting.
• JOHNSBURG ROAD: Only westbound traffic is allowed to travel along the road from Chapel Hill Road to Cherokee Drive. Eastbound traffic is being rerouted through a Route 31, Route 120, Chapel Hill Road detour.
• INTERSTATE 90 AND ROUTE 47: Be prepared for slower traffic along Route 47 as work continues to create a full interchange.
Also on I-90, watch for workers who are rebuilding the Route 20 overpass.
• WESTERN BYPASS: Watch for workers and delays as workers continue a $33 million project to build a 2-mile, four-lane highway west of downtown Algonquin to relieve congestion on Route 31.
Algonquin Road between Main Street and Meyer Drive will be down to one lane through this fall. Watch for lane closures on Route 31/Main Street. South Main Street has one lane closed between Edgewood and Huntington drives, and North Main Street has one lane closed between Cary-Algonquin Road and Linden Avenue.
Huntington Drive will remain closed between Circle Drive and South Main Street through summer 2014. A detour to Edgewood Drive is posted.
• WALKUP ROAD: Work on the Walkup Road project is wrapping up.
Final paving is wrapping up, and the flashing beacons at a pedestrian crossing and the multi-use path crossing will be activated this week. The permanent traffic signals at Route 176 and Walkup Road are set to be activated Thursday.
The three-phase project widens and improves about 6 miles of Walkup Road between Bull Valley Road and Route 176.
• ROUTES 31 AND 176: Workers closed East Terra Cotta Avenue, east of the intersection, on April 16. Watch for workers.
