update | impact | schedule | purpose | news
The Illinois Tollway is rebuilding and widening the North Tri-State Tollway (I-294/I-94) throughout a 39-mile corridor to provide congestion relief. The project includes reconstructing and widening to four lanes in each direction of the North Tri-State Tollway between Dempster Street and IL Route 173. Four lanes are now open in each direction between Grand Avenue and IL Route 173. Work to reconstruct the roadway north of IL Route 173 to Russell Road and resurface pavement from Russell Road to the Wisconsin state line is complete. This work is part of the Tollway's Congestion-Relief Program to reduce travel times.

today's daily report of system-wide lane closures...]
A work zone configuration is in place with Express and Local Lanes between Dempster Street and Lake Cook Road and between Grand Avenue and Half Day Road. One northbound lane is shifted to the southbound side of the road and two Local Lanes are on new pavement on the right lane and right shoulder on the northbound side in order to keep three lanes open in each direction.

Update – Counterflow lanes
The work zone configuration will remain in place through the 2009 construction season. Traffic exiting at Willow Road , Half Day Road, Townline Road , and Belvidere Road must stay in the Local Lanes to exit. Traffic exiting at Lake Cook Road is directed to exit the Express Lane just north of Sanders Road to access the exit. Traffic exiting at Rockland Road is directed to exit to the Local Lanes just north of Townline Road ; traffic exiting at Grand Avenue is directed to exit to the Local Lanes just north of Belvidere Road.
Bridge Construction Update
Several bridges are being rebuilt and lengthened to accommodate mainline construction. Bridge work is scheduled at Ballard Road , Golf Road , Central Road , Milwaukee Avenue, Lake Avenue , Sanders Road , Half Day Road, Rockland Road (IL Route 176), O'Plaine Road , and Washington Street . Bridge work is complete at Lake Cook Road , Willow Road, Belvidere Road , Rosecrans Road (IL Route 173), Grand Avenue , and at U.S. Route 41.
Half Day Road – All traffic is now traveling on the newly reconstructed eastbound side of the bridge while the westbound side of the bridge is closed for reconstruction work.
Rockland Road – One lane in each direction on Rockland Road under I-94 is closed for bridge abutment work.
O’Plaine Road– The southbound lane on the bridge is closed for reconstruction work. Temporary traffic signals are in place to maintain traffic in both directions using the newly reconstructed northbound lane on the bridge.
Crossroad bridge construction is being staggered to reduce inconvenience. The bridges remain open with staged traffic and reduced lanes. The Tollway is coordinating bridge work with IDOT, Cook County , and Lake County to minimize the impact to local roads, but delays are expected.

Minimizing Impact to Reduce Delays
Three lanes of traffic will remain available in both directions during daytime hours throughout this project through the use of counterflow lanes and shoulders. Lane closures will be permitted off-peak only to minimize the impact to traffic.

Work Zone Safety
Construction zone speed limits are in effect in all construction zones 24/7 and drivers should continue to watch for changing traffic patterns and use caution, especially when workers are present. Reduced speed limits will be in place on bridges under construction, while a 45 m.p.h. speed limit will be in place on the mainline. See the Tollway’s Work Zone Safety page.

Purpose – Pertinent Details on Why and How
Rebuilding and widening the section of road to four lanes in each direction from Dempster Street to IL Route 173 and rebuilding from IL Route 173 to Russell Road will provide congestion relief and reduce travel times. The Tollway is coordinating work with local, county and state transportation officials on work to reconstruct I-294/I-94. When Rebuild & Widen Projects on the north, central and south segments are complete, the Tri-State Tollway will provide four lanes in each direction from Indiana , up to the north end of the system near the Wisconsin state line.
