How much has traffic decreased on Michigans Mackinac Bridge this summer?
Like everywhere else, the Mackinaw Bridge traffic count has dropped this summer, due to the rising gas prices and poor economy. “Traffic on the Mackinac Bridge, which connects Michigan’s upper and lower peninsulas, was down 11.2% in June compared with a year ago but revenue is up 6.8% for the year because of toll hikes, says Bob Sweeney of the Mackinac Bridge Authority.” http://www.usatoday.com/news/nation/2008-07-30-Tolls_N.
