Lower speed limits in construction zones may be having a good effect on traffic — especially along a stretch of Interstate 39-90 near Janesville. The Wisconsin State Patrol and Department of Transportation report citations are way down this year. In April of last year, nearly 700 drivers were cited during traffic stops. That number is just 232 in the same month this year. Only 31 accidents happened in work zones. Fair warning — troopers will be out in force for the holiday weekend, including aerial enforcement.
