The Stone Arch Bridge is a former railroad bridge crossing the Mississippi River at Saint Anthony Falls in downtown Minneapolis, Minnesota. It is the only arched bridge made of stone on the entire length of the Mississippi River. Walk on and along the bridge, enjoy views of the Mississippi, and explore the ruins of the old Gold Medal and Pillsbury flour mills, all while being in the heart of downtown Minneapolis. (afterwards, take an ice cream break at Izzie's Ice Cream just down the street! )
