^River Miles in the Upper Mississippi are reckoned in statute miles starting at zero at the confluence with the Ohio River in Cairo, Illinois. For other rivers shown, the mileage is reckoned starting at zero with the confluence of that river with the Mississippi.
^Except as noted, information for the reaches from the Coon Rapids Dam downbound is sourced from "Upper Mississippi River Navigation Charts", US Army Corps of Engineers (ACOE), 2011. More recent data from the ACOE is only published in electronic chart form and is not, as of 2018, available in book format. Information indicated as source to Navionics is retrieved from http://webapp.navionics.com.
^The navigation channel is crossed by a straight span and is not arched
^There is an overhead obstruction approximately 30 feet above upper pool just upriver of the upstream gate; a gantry for the crane used to remove hydroelectric turbines for service. The exact clearance is not published. C-map reports 28.5 clearance for the adjoining Cedar Avenue bridge which is clearly low and may be an attempt to capture the gantry height.
^Vertical bridge clearance in feet above normal pool except as noted. Arched bridges have greater clearance at the center. Clearance sources are ACOE except as noted
^Source: Navionics. River left span 62.2 when open, 23.2 when shut. Other sources report that the rail line is unused and that the bridge is left open at all times.
^63.0' powerline clearance for powerline adjacent to bridge - bridge is arch shape with approximately 149' clearance at center - 38.5 at high water
