Before the Bridge - Story of the Mackinac Straits Ferries |
This is the story of the fleet of ferries and their predecessors that formed the first link between Michigan's two peninisulas. Today travelers cross the Mackinac Straits via the Mackinac Bridge without ever leaving their cars, but untill 1957 it was necessary to take a break from driving in order to cross via one of the many state-operated ferries. The carferries operated along with the famous train ferry "Cheif Wawatam". While the 'Chief' operated into the 1970's, carferry service ended on November 1, 1957 (after the Mighty Mac was opened). Take a trip with us back in time and see what straits travel was like before the bridge. Through the use of rare color footage and interviews with former ferry workers, we'll make this journey possible. | DVD | 55 minutes | grades 4-12 |
