Although it may seem like the Dan Ryan is backed up all day, there are times when traffic volumes are low - and - motorists are driving too fast. Speeders on the Dan Ryan Expressway who are nabbed by photo-enforcement vans that rolled out this weekend will start receiving $375 tickets in the mail in the next two weeks. The white van, parked on the shoulder in the Dan Ryan construction zone, has a message board that tells you your speed as you pass by...but if you're speeding, it's too late, because inside, the photo radar enforcement is giving you a ticket.
