Interstate 680 is the beltway wrapping around the northern and western sides of Omaha, Nebraska, but a small piece of it extends into Iowa. About three of the highway's sixteen miles occur in Iowa, north of Council Bluffs, ending at Interstate 29. Interstate 680's entrance into Iowa is a bridge over the Missouri River about five miles north of downtown Omaha. The highway passes through a single diamond interchange with a local side road before ending at a cloverleaf interchange with Interstate 29. Beyond the cloverleaf, the roadway continues east as County Route G37, a two-lane road bound for the tiny town of Crescent, Iowa. Interstate 680 once continued onto Interstate 29 north, and then onto another freeway extending farther east. That freeway, as of just a few years ago, is now designated as Interstate 880. The eastern end of Interstate 680 was truncated to Interstate 29, where it ends today.
First, here is the image providing the source of my Interstate 680 shield image (seen in the menu page). This sign sits on the rural side road accessed by Interstate 680's exit numbered as "exit 1". The sign faces north to southbound cars, directing them to the eastbound onramp on the south side of the interchange. This photo was taken in October 2021.

Interstate 680 crosses into Iowa from Nebraska, with use of a bridge over the Missouri River north of Omaha:
The lone intermediate exit between the Missouri River and the eastern end of Interstate 680 is to a loosely-named "County Road", at exit 1:
It's the beginning of the end; here's the first ramp at Interstate 680's final interchange, leading to Interstate 29's southbound carriageway:
The final exit is the cloverleaf ramp to Interstate 29 north, toward Sioux City. Note the railroad grade crossing in the background, right alongside the interchange. You can also note the green-out covering up the former Interstate 680 shield, which would have indicated Interstate 680's former continuation onto Interstate 29 north. When the section of Interstate 680 east of Interstate 29 was renumbered to Interstate 880, that continuation was canceled to make the scene in this photo the new termination of Interstate 680.
