U.S. Route 166
Encyclopedia
U.S. Route 166 is an 166 miles (267.2 km) east–west United States highway. This route and US-266 are the only two remaining spurs of historic U.S. Highway 66, since US-666
was renumbered in 2003.
US-166 meets the old route of US-66, now designated Alt US-69, in Baxter Springs
in the southeast corner of Kansas
.
As of 2006, the highway's western terminus is in South Haven, Kansas
at an intersection with US-81, approximately 1 miles (1.6 km) north of the northern terminus of U.S. Highway 177. From this point, it heads east for about four miles (6 km), where it intersects the Kansas Turnpike
(Interstate 35) at exit 4. It then enters Arkansas City
, where it meets US-77 and overlaps it for approximately two miles, splitting off near Parkerfield
.
US-166 crosses into Chautauqua County
shortly before passing through Cedar Vale
. It runs south of Sedan
, intersecting K-99
. Near Havana
, US-166 has an interchange with US-75, where the two routes begin a concurrency. US-166 splits off just north of Caney
. It has a brief concurrency with US-169 in the Coffeyville
area. It also overlaps US-59 through Chetopa
before crossing U.S. Route 69 north of Treece
. In Baxter Springs
, it crosses US-69 Alternate before joining with US-400 west of town. Just before crossing into Missouri, it serves as the southern terminus of K-26
.
U.S. 166's eastern terminus is southwest of Joplin, Missouri
at an intersection with Interstate 44
0.6 mile (0.965604 km) from the Kansas
border. It is also about 1000 feet (300 m) from the point where Kansas, Missouri
, and Oklahoma
meet. U.S. Route 400
also ends here, and the routes are co-signed from this point to near Baxter Springs, Kansas
, a distance of approximately 10 miles (16.1 km).
to South Haven
. In 1945, it was extended east through Joplin, Missouri
, where it paralleled U.S. Route 66
to Springfield, Missouri
. This extension absorbed Route 38, which had been formed in 1922 from Carthage to west of Springfield and realigned to Joplin in about 1930, with the former route becoming Route 38N and soon U.S. Route 71 Alternate. In 1966, following the completion of the last section of Interstate 44
in Missouri, the east end of US 166 was truncated back from Springfield to its current terminus. Most sections of US 166 between Joplin and Springfield were not upgraded to Interstate Highway standards and were renumbered as I-44 Business Loops, state highways (such as Route 174) or turned over to local or county jurisdiction.
