The West Portal

There seems to be some confusion about the name of the road here. The camera seems to be on Plank Road, paying homage to when this was the Watertown Plank Road, a wooden paved toll road that went from Milwaukee to Watertown. The addresses of the businesses to the east, including the car dealer and The Kiltie drive-in, are on Wisconsin Avenue. Some maps show the name of the road, west of the bridge as Plank Road, as Wisconsin Avenue east of the bridge, then Plank Road east of The Kiltie. Anyone know the story?

The Deck and North Railing

The concrete railing is typical of bridge design of the 1930's and 1950's of bridges built to Wisconsin State Highway Commission specifications. Note the prestressed concrete stringer to the left, that carries modern STH 16 across the Oconomowoc River.

The Pedestrian Walkway

Well, it was anyway, until it was obscured to hold buttresses to mount the modern steel guard railings.

The North Face

With no pedestrian walkway to hold butresses, a modern steel guardrail is bolted to a modern steel guardrail through the balusters.

The North Side

Note the steel box that carries storm water from the deck to the river. There is a matching steel conduit on the east end of the bridge, out of view.

History

Design
Although this is not a historically significant bridge in and of itself, it is typical of bridges built to standards set by the Wisconsin State Highway Commission for many years. These bridges are being replaced at an alarming rate, this one has survived (so far) because old STH 16 (Wisconsin Avenue) has been replaced by a modern superslab, demoting this old highway to frontage road status.
