Significance of the Cobban Bridge 

Written by Diane Kromm, Wisconsin Historic Bridges Recording Project, Summmer 1987

The Modern Steel Structures Company of Waukesha constructed the Yellow River Bridge across the Chippewa River in 1908. The firm, incorporated in 1900, developed the most modern and complete steel structural plant in the West. Between 1916 and 1918, the Wisconsin-Minnesota Power & Light Company built a hydroelectric dam four miles downstream from the bridge, putting the site under water. The townships of Eagle Point and Arthur arranged to have the 486-foot span dismantled and re-erected 15 miles upstream near the village of Cobban. The Cast Stone Construction Company, in Eau Claire, installed the new concrete substructure. Crombley and Thailacker, a Milwaukee bridge-building firm, apparently erected the steel work. The Yellow River Bridge is the oldest of four Pennsylvania truss bridges remaining in Wisconsin.

And a 169 Average Daily Traffic count gives even more reason that a restoration is the more feasible option!

Also, that supposed $13 Million price tag to restore the bridge is an inflated joke and nothing more than an attempt to thwart preservation... Unless they are planning to Gold plate it!

Its also a meaningless decision until Section 106 is conducted (as far as I know it hasn't been unless they have conducted it without my knowledge despite requesting consulting party status). No Section 106 = No Federal Funds.

Irresponsible and short-sighted decision, but sadly it seems to be ingrained into government officials in Wisconsin that history means nothing and these landmarks are simply scrap metal... Truly sad indeed!

This historic bridge is closed indefinitely. The Chippewa County Board voted to build a replacement bridge if Federal and State money is approved. It appears as though the historic bridge will soon be demolished to make room for the new bridge that may be competed by 2021. Anyone want to buy a beautiful old bridge?

I'd love to see the details of that $13,000,000 rehabilitation proposal... Could use a good laugh!

Hello,

I was traveling through Wisconsin, and came upon a bridge. It inspired me.

...just found out that it might be taken down (it would really be a shame to loose this bridge)

The noted news article proposes replacing the bridge with federal funds, any proposal that has an adverse effect to this historic bridge will trigger Section 106. If Section 106 has not yet been conducted it is required under federal law to consider all feasible and prudent alternatives to demolition: an alternative needs to include a detailed consideration of rehabilitation.

The news isn't good. Looks like saving the Cobban Bridge in any fashion isn't one of the options on the table:

Due to recent local news articles about possibly not replacing the bridge, I have started a Facebook page titled, Save the Cobban Bridge. Please LIKE the page to see links to the news articles and other information about the bridge. As new information becomes available I will add it to the page.

This is the last Pennsylvania truss in the state yet is at risk for demolition.
