What are those squares on the road?

Today, I was notified by an engineer at Chamlin and Associates that his firm will be conducting traffic counts next week in LaSalle on the following roads:

• Canal St.
• Marquette St.
• Fourth St.

This means you will probably see small black squares taped down to the pavement in these areas. The squares count the number of vehicles that travel down that road and keep track of the time each vehicle went by.

The traffic counts are needed for an engineering study Chamlin and Associates is working on for the state of Illinois to help determine the route for the Alliance Trail. You can find out more information about the project by visiting the IDOT Website.
