Irish Road Bridge


Oblique View East Elevation

The bridge is actually oriented SE-NW so this is actually the NE elevation, looking WNW.

This bridge is on Calumet County's list of bridges of historical interest that was published by Calumet County in 2007.

Calumet County's Historic Bridges 

Written by J.R. Manning

Calumet County published a document in April 2007 called the Calumet County Inventory & Trends Report. It is a 339 page comprehensive planning report of housing, transportation, utilities, agriculture, industry, commercial development, land use and more tables and maps than you can imagine. In it, the county pointed out nine bridges in the county of notable historical interest, some of them more than 100 years old. Several were hand built of stone.

The nine bridges listed in the report are:

Irish Road: Built in 1920, a 17 wide bridge over the north branch of the Manitowoc River.

Hayton Road: Built in 1900, a 27 wide bridge over Pine Creek.

Lemke Road: Built in 1918, a 19 wide bridge over the Killsnake River.

Weeks Road: Built in 1900, an 18 wide bridge over the south branch of the Manitowoc River.

Killsnake Road: Built in 1925, a 27 wide bridge over the Killsnake River.

Grand Street: Built in 1927, a 30 wide bridge over the south branch of the Manitowoc River.

Charlesburg Road: Built in 1930, a 22 wide bridge over Pine Creek.

Man-Cal Road: Built in 1922, a 24 wide bridge over a tributary to the East River.

Mud Creek: Built in 1930, a 19 wide bridge over Mud Creek.

Some of these bridges don't look terribly significant at first glance, especially to a dedicated bridge hunter. Still, the county fathers feel these are of historical significance, and who are we to argue? After all, how many counties have actually published a list of their historical bridges? As long as Calumet County says these are of significant historical interest, this Bridge Hunter isn't going to disagree, so here they are.

You can read the report yourself on the Calumet County official website. (The Historic Bridges are listed on page 225.)
