660 miles that day...Muskegon, MI to Wausau, WI. Nice relaxing little ride.
Tis about the same distance I did the bridge day as well. Massey, ON to Columbus, OH. Had a flat coming over the Int'l bridge, but luckily at the end of it, and was able to get a tow to a dealer (thank you AAA+ with RV coverage, and not a mile too soon as it's not honored in CA.
You know, come to think about, maybe my Mackinaw bridge experience was tainted. I had to have a 160 tire Avon spooned on since there were no correct fits anywhere within 100 miles of Sault Ste. Marie. So I crossed the big bridge at Mackinaw coming south with a 160 with full touring rig. No matter, even the toll booth lady carried on about being careful, high winds today. I was like yada yada, I can ride, been over bridges...until I realized...FUUUUUCCCKKKK!!!!! It's windy and there is no traction!!!! And I can see the water 200 feet below the metal grid!!!
Here's some cool facts about the bridge from WIKI:
The Mackinac Bridge is the longest two tower suspension bridge between anchorages (8,614 feet) (2,626 m) in the Western Hemisphere. Much longer anchorage-to-anchorage spans have been built in the Eastern Hemisphere, including the Akashi-Kaikyo Bridge in Japan (12,826 feet) (3,909 m). However, because of the long leadups to the anchorages on the Mackinac, from waterline to waterline it is much longer than the Akashi-Kaikyo (5 mile compared to 2.4 mile).
The length of the bridge's main span is 3,800 feet (1,158 m), which makes it the third-longest suspension span in the United States and tenth largest worldwide.
Length from cable bent pier to cable bent pier: 7,400 feet (2,256 m).
Total width of the roadway: 54 feet (16.5 m)
Two outside lanes: 12 feet (3.7 m) wide each
Two inside lanes: 11 feet (3.4 m) wide each
Center mall: 2 feet (0.61 m)
Catwalk, curb and rail width: 3 feet (0.91 m) on each side
Width of stiffening truss in the suspended span: 68 feet (20.7 m), making it wider than the roadway it supports.
Height of the roadway at mid-span: approximately 200 feet (61 m) above water level.
Vertical clearance at normal temperature:
155 feet (47 m) at the center of the main suspension span.
135 feet (41 m) at the boundaries of the 3,000 feet (914 m) wide navigation channel.
Construction cost: $99.8 million (1957 USD)
Height of towers above water: 552 feet (168 m)
Max. depth of towers below water: 210 feet (64 m)
Total length of wire in main cables: 42,000 miles (68,000 km).
Total vehicle crossings, 2005: 4,236,491 (average 11,608 per day)
Speed limit: 45 mph (72 km/h) for passenger cars, 20 mph (32 km/h) for heavy trucks. Heavy trucks are also required to leave 500 feet (152 m) spacing ahead.
Two vehicles have fallen off the bridge.
Twenty-four year old Leslie Anne Plouhar died in 1989 when her 1987 Yugo plunged over the 36 inch high railing. A combination of high winds and excessive speeding was blamed.
In March 1997, a 1996 Ford Bronco went over the edge. It was later determined to be a suicide by driver Richard Alan Daraban.[4]
