MLive.com has obtained public records that explain why the Mackinac Bridge Authority is still unable to accept credit card payments at its tollbooths, a service it said two years ago it would initiate. The article details how “technical glitches, stalled contract negotiations and a near-six month unexplained absence of the primary subcontractor have seriously delayed the project, which is now several hundred thousand dollars over the initial budget.” MLive adds that deploying a swipe-and-go payment option for Mackinac Bridge customers is “one of the final hurdles” in completing a multiyear software upgrade project that also involves the Sault Ste. Marie International Bridge and the Blue Water Bridge.
