After coming up through the south end of Falls City, the U.S. Route 159 turns east (with Route 73 continuing north). After the eastbound turn, U.S. Route leaves the state at the Missouri River bridge in Rulo, Nebraska.

### Missouri

U.S. Route 159 enters the state of Missouri crossing the Missouri River near the Rulo bridge south of Big Lake, Missouri. It crosses Interstate 29 near Fortescue, Missouri before ending at US-59 near New Point. Its total length in Missouri is approximately 16 miles (26 km).

## History

When the route was commissioned in 1934, U.S. Route 159 only went between Nortonville, Kansas and Horton, Kansas. In 1945, it was extended north to Craig, Missouri via Falls City, Nebraska. After 1975, the route in Missouri was altered to go east from the Fortescue area to what is now its current terminus near New Point, Missouri. The old route which went to Craig is now Route 111.
In 2013, a new bridge over the Missouri River, located about 650 feet south of the old Rulo Bridge, opened to traffic. In April 2019, a large portion of this route was closed for several months because of flooding of the Missouri River. The bridge and the road between Rulo, Nebraska and Missouri Route 111 was reopened in September 2019, and the remainder of the route to Interstate 29 was reopened in late October.
