Minnesota State Highway 43 (MN 43) is a highway in southeast Minnesota, which runs from its intersection with State Highway 44 in Mabel and continues north to its northern terminus at the Wisconsin state line at Winona, where it becomes Wisconsin Highway 54 upon crossing the Mississippi River.
Highway 43 is 45 miles (72 km) in length.
The route crosses the Root River in Fillmore County.
Highway 43 passes through the Richard J. Dorer State Forest.
The northern terminus of Highway 43 is at the Mississippi River at Winona, where the route becomes Wisconsin Highway 54 upon crossing the Main Channel and North Channel bridges over the river to Wisconsin.
A major project in the 1980s to rebuild Highway 43 from Interstate 90 to Winona as an expressway ran out of money. Only one carriageway was actually paved. There is still visible road bed and bridges east of the roadway in this section.
In response to the I-35W Bridge collapse in Minneapolis on August 1, 2007, all Minnesota bridges were ordered to be inspected. During an inspection, "gusset plate corrosion issues" were discovered in the Main Channel Bridge (Highway 43 / Highway 54), which crosses the Mississippi River between Winona, MN and nearby Fountain City, WI. The Main Channel Bridge (Bridge #5900) was closed to traffic on June 3, 2008. Mn/DOT made a statement this was due to gusset plate corrosion issues similar to those that caused the I-35W Bridge to collapse. The Main Channel Bridge reopened to car traffic on June 14, 2008. Commercial vehicles were still directed to find alternate routes across the river. The bridge was scheduled for replacement in 2017, which has been moved up to 2014.
