The Mackinac Bridge

The Mackinac Bridge, as seen the night of July 8, 2026, from the Upper Peninsula. The famous Michigan bridge is a marvel of human engineering. It spans the Straits of Mackinac (mak-in-aw) which separate lakes Michigan and Huron and connects the Upper and Lower peninsulas.

Opened on November 1, 1957, the bridge is five miles long, and those twin towers are 552 feet tall. The straits regularly experience gale force winds, and the center lanes are an open grid of steel mesh to allow air flow through and minimize lift of the deck during gales. The center span can laterally shift a remarkable 35 feet during high winds.

The Mackinac Bridge Authority offers a driver's assistance program, as some drivers are too frightened to drive across (motorcycles, too). I do not know what the drivers do - hide in the trunk? 

Looking for an exciting job? All of those lights on the cables (42 thousand miles of wire in the main cables) are replaced by hand. Workers (steeplejacks) climb the cables to reach the fixtures.

I've been across this bridge many times, and it never grows old. If you want to walk across, the bridge is closed every Labor Day, and anyone that wants to walk across can do so.

PHOTO NOTE: I think the bridge photographs better at night, and not just because the lights are visible and create a cool effect. During the day, big as it is, the bridge can get a bit lost in the mass of water around it. Probably, with certain early morning or late day lighting it could look great, but I've not yet had the fortune to be there at such times. But the Big Mac certainly pops at night.

A wide-angle, such as my go-to Canon 16-35mm f/4, is too wide in my opinion. Even at full zoom, it leaves too much blank water space around the bridge. This is a case where a moderate-range zoom lens is great, and I used my 70-200mm f/2.8 for this shot. I zoomed a bit - to 145mm - to cut off much of the long approach on the left that is on a built-up earthen berm rather than a proper bridge (even though it counts as part of the bridge). Once the camera rig is set up, it is just a matter of zooming and composing to position the bridge so that it looks good to you.

A tripod is an absolute must in order to photograph the Mackinac Bridge properly, in my view. Especially at night, due to the long exposure that will be required. I made this photo at f/22 (lots of depth of field), and ISO 400 (a low ISO is always desirable for clean files, and I could have gone even lower. But the R5 handles higher ISO's very well, and 400 is hardly a high ISO). The shutter speed was a turtle-like VERY slow 4 seconds. But who cares about that - shutter speed is essentially irrelevant if your camera is on a stable platform (tripod) and the subject is not moving.

As almost always when making such long exposure images, I use the two-second timer delay that is built into the camera's drive mode menu. Once I activate the shutter button, I move away from the rig while the camera beep beep beeps... and two seconds later the shot is fired. That ensures that the operator can't accidentally wiggle the rig while depressing the shutter.
