Just down the road from the Merrill City Hall, is Historical Marker 471 – Three Arch Stone Bridge.
Just behind the marker are the nifty arches themselves.
Just down the street in the other direction (east, toward City Hall) is another interesting monument about the River Rat.
You can’t really park on the street by these sites. Fortunately, there’s a nice little park – Kitchenette Park – just across the street.
