This is just outside of Iowa, but important to the southwest. (It also means I have to go back there and travel across it to re-clinch US 159.)
This Lincoln Journal-Star article errs in saying the bridge connects Richardson County NE to I-29 in Iowa. US 159 goes into Missouri and meets I-29 about 35 miles south of the state line, but then travelers obviously can travel north into Iowa from there.
The US 159 bridge is near the southeasternmost point of Nebraska and one of two bridges connecting Nebraska and Missouri.
