Illinois' transportation department is suspending road construction where possible to ease traffic congestion on the busy Labor Day weekend.
Acting Transportation Secretary Ann Schneider says advance notice of construction-zone status will help thousands of motorists plan trips and travel safely.
Starting at 3 p.m. Friday, transportation officials will suspend all non-emergency road work and open up all lanes where possible through Monday night.
Some construction zones will still have closed lanes.
Officials are urging motorists to slow down, obey speed limits and drive with caution. Work zone speed limits are still in effect where posted, even if no workers are present.
