The back of the postcard above notes, "The Western Gateway to the famous Peninsula resort section. Fishing, boating and swimming are the main sports. Excellent cottages and cabins available to the tourist. A public picnic ground and tourist camp located on lake front."
According to the Historic Bridges.org website, the bridge was built in 1933 and rehabilitated a few times, as recently as 2007.
And here's my shot from this past weekend. I was fairly creeped out standing so close to the edge of the water behind the Port Clinton Fisheries Inc.
Here's another vintage postcard, this time with a more distant view.
And finally, a modern postcard.
