The road is the shortest highway in Iowa. It is totally within
the town of Carter Lake,
Iowa and is the only Iowa highway west of the Missouri
River.
Although Carter Lake is west of the Missouri River it is part of
Iowa. Prior to 1877 it was connected to Council Bluffs,
Iowa by a large oxbow curve in
the Missouri River. In 1877 the river straighted its course
in a flood. The U.S.Supreme Court ruled that it was still part of Iowa rather than
Nebraska even though
it is surrounded by Omaha and separated from Iowa by the new
Missouri River channel.
After Eppley Airfield was built in the river bottoms to the east of
Carter Lake, the shortest route from downtown Omaha to the airport
was Abbott Drive which was routed through Carter Lake. Carter Lake
initially maintained its section as a municipal road. When plans
were made to upgrade to a jet port, the Iowa Department of
Transportation took over the road. It has posted highway signs on
the road as well as Iowa welcome signs on both ends. Abbott Drive
is a municipal road in Omaha and so there are no Nebraska highway
signs or Nebraska welcome signs.
