Illinois officials will suspend road construction where possible to ease traffic flow for the Easter holiday weekend.

The Department of Transportation says some traffic lanes must remain closed.

Officials say all non-emergency work will be stopped at 3 p.m. Friday and open lanes where possible through midnight Sunday.

Transportation Secretary Ann Schneider says less congestion will make travel safer.

She urges motorists to slow down, obey speed limits and drive with caution through work zones.

Work zone speed limits are in effect even if no workers are present.
