While private enterprise for the most part has been able to hold costs and effects of inflation in check, in many cases through efficiencies and watchful management, government does no such thing.  An infrastructure operation that is run by government hasn't the same incentives, or mechanisms that allow increased costs to be aggregated along side found savings.  The Price will always go up. And the announcement of rate increases over one international bridge?

"The Sault Ste. Marie Bridge Authority (SSMBA) today reminded International Bridge customers of public hearings next week in Michigan and Ontario to review a proposed toll rate increase.

The proposed increase was prompted by the SSMBA Board of Directors' review on Aug. 15 of its long-range financial plan that details the operational and capital improvement project needs of the bridge for the next 30 years. The proposed toll increase (in U.S. dollars) includes an increase in passenger vehicle tolls from the current $3 per trip to $3.50 per trip on April 1, 2014, and from $3.50 to $4 on April 1, 2019."
