#819 The
Mackinac Bridge.
Mackinac (pronounced "ma-kuh-naa") Bridge, connects lower and upper peninsulas of the state of Michigan. Opened in fall 1957, it was under construction from 1954 to 1957.
One of the longest suspension bridges in the world, both when it opened, and even now (seventh longest based on suspended length). In total, with approaches, its almost 27,000 feet long.
Its main towers' (two of them, each 500 feet tall) foundations extend 200 BELOW the waterline down to bedrock -- the deepest of ANY bridge ever constructucted.
I included this primer because I use it to try answer question 3.
Below, this ordinary citizen's family photo from late 1950's, from lower peninsula Lake Michigan shoreline, west side of bridge looking north. shows:
(1) how far out into the water (straits of Mackinac) the towers are, in turn
(2) how far FROM the shore before the suspension cables reach road level, and
(3) parts of the bridge on either side of the towers called "side spans" (suspendesed roadway, built on "piers - there are about 30 of them in total)

Today, the bridge is painted green and ivory. It got it first coat of point in 1958 (a light blue towers, greenish superstructure), but for the three years it was underconstruction, the steel had a "rusty" color. It is likely, the illustrator started their illustration WHEN the bridge was UNPAINTED.
Artistic license.
In about 2016, the whole bridge was repainted from the light blue/green (which was LEAD paint from the late 1950's) to the current ivory and green. That color itself was used by an illustrator in 1957. Yes, 70 years later, Michigan decided they liked those colors. and used them in the repaint.
Artistic license.
This could be why bridges OTHER than Mackinac come up in google searches. It was a rusty color WHILE it was being built. Its been painted some other color (light blue, or ivory/green) since June 1958.

All that to say, Question 3.
UNLESS the 1958 Pontiac was based on a photo of the car ON a ferry/barge, you
CANNOT get such a pic, today or back then either.
Of course, the illustrator can DRAW the car anywhere they want. But to get that view in real life, thats (that close to the towers, about where the side spans end and the cables are attached) about a MILE from either shore of Lake Michigan, you gotta be out in the straits.
Heck, you can even see the sky through what would need to be roadway - this suggests a pre-bridge opening inspiration for the illustrator.
As such, LSS I conclude
artistic license, trying to capitalize on whiz bang architecture of the times going on with the Mighty Mac.
Another thing. (ignoring the towers are nearly a MILE from the shore) NOT sure in the post 9/11 era you can get vehicles this close to the shore NEAR the suspended side spans, anymore. You can still walk down there, ride, etc.. But a vehicle? Dunno, since I havent been there in 25 years with a vehicle.
