MONROE - Green County Highway Commissioner Jeff Wunschel is urging motorists to drive carefully in highway work zones as the maintenance and construction season begins throughout Wisconsin. As the weather turns warmer, work zones will be more prevalent, putting more highway workers and drivers at risk. In 2013, the most recent year in which data is available, the Wisconsin Department of Transportation reported that there were nearly 1,600 work-zone crashes in the state, resulting in 629 injuries and nine fatalities.
