Starting at the Lecompton interchange of I-70 and the Turnpike, K-10 traverses south,
interchanging with US 40 and skirting around Clinton Lake before turning east to US 59. K-10
follows 59 north about a mile and a half through the southern end of Lawrence before turning
east again. Once out of Lawrence, K-10 races across the Kansas River valley, racing through
Eudora and De Soto and skirting the northern edge of Olathe before ending at the southwest
corner of the I-435 beltway about a mile short of I-35.
History
In 1929, K-10 began at US 50N at Herington,
proceeded north and east through White City, Dwight, Alta Vista, and Alma, and McFarland before
turning east at Paxico and entering Topeka on 10th Avenue to
US 75, then north across the Kansas River at the
Topeka Boulevard bridge. Once across the river, K-10 followed the north bank of the river, and
turned east through Grantville, Newman, and Perry before meeting
US 73W at Williamstown. K-10 followed US 73W through
Lawrence before turning east to Kansas City. By 1932, K-10 had been paved from Kansas City west
to the Douglas/Johnson County line, and from Lawrence to Grantville; as well as gravel from the
Douglas/Johnson County line to Lawrence, west out of Topeka to Valencia Road, and between Paxico
and Alma.
In May 1935, the road was in the process of being paved from the Douglas/Johnson County Line to
Eudora, and bids were taken to finish paving the road west to Lawrence. A Newspaper article from
May 1935 indicated that the newly-paved roadway would feature an "experimental" section - a 20-foot
road on 120-foot right of way, with shoulders and ditches to meet the specifications of a "modal
highway" At the same time, the highway was being paved from Topeka to Valencia Road, and graveled
from Paxico to Alma as well as Alta Vista to Dwight. The May 1935 article indicated that K-10 would
be rerouted on the aligment of US 40 south of the Kansas
River, while US 40 would follow K-10's alignment north of the river, easing congestion in Downtown
Lawrence. K-10 was routed onto US 40's alignment, but US 40 was not re-routed. Instead,
US 24 was introduced, extending west into Kansas City and
taking K-10's northern alignment, with the southern alignment from designated as US 40/K-10.
By 1941, the alignment between Valencia Road and Paxico was straightened and graveled, and graveled
from Alta Vista to Herington. By 1954, the entire route was paved between Topeka and Alma and
between Alta Vista and Dwight. The part between Dwight and Herington was paved by 1956. At the same
time, a new connection from K-99 between Eskridge and Alma was built west to Alta Vista, bypassing
the last unpaved section of K-10 (which had been graveled). In 1957, K-10 between K-99 and Topeka
was re-designated as US 40, and K-10 between Herington and K-99 was re-designated as
K-4, shifting the west end of K-10 to Lawrence.
Prior to 1956, K-10 and US 73W (later US 59) were routed
along Massachusetts Street through Downtown Lawrence to US 40. When a new road, today known as Iowa
Street, was built on what was then the west side of town, K-10 and US 59 were routed along it to 40.
The K-10 Freeway began construction in 1974. The first section completed was the section from
Lexington Avenue in DeSoto to K-7 north of
Olathe, which opened to traffic on November 8, 1976. The section from Lawrence to DeSoto opened
in 1978. The section from K-7 east to I-435, at first known as
K-12, began construction in 1980. In August of 1982, the
grading was completed, but work stopped until the beginning of 1984. The last stretch of road was
completed December 18, 1984. At the time the freeway was being planned, the highway commission
considered re-aligning K-10 to bypass Lawrence. Although the bypass was dropped, it would be revived
by Douglas County.
The South Lawrence Trafficway was first proposed by the Lawrence Chamber of Commerce in 1985. Douglas
County issued $4 million in bonds to entice KDOT to fund the route. A 1987 lawsuit by Les Blevins of
rural Lawrence challenged the county's authority to issue the bonds without a public vote.
Ultimately, the Kansas Supreme Court ruled that Douglas County should have held a vote, initially
ordering the bonds suspended pending a vote. Later, the ruling would be revised to indicate that
Douglas County's bond issue could proceed without a vote; however, similar issues in the future
would require a public vote before the bonds are issued. A referendum on the SLT bonds was held in
November of 1990 in favor of the road. Opponents sued again, saying that a explanatory statement was
biased. The Kansas Supreme Court ruled in 1992 that due to the circumstances, the referendum was
advisory, meaning that the county could legally proceed on the trafficway even if the referendum had
been rejected.
The SLT began construction on the western leg in 1994 and completed in late 1996. In 1993, Haskell
Indian Nations University complained that the SLT as proposed would negatively affect the university,
particularly cultural and religious practices held along the south end, near where the trafficway
was to be built. The Federal Highway Administration ordered a Supplemental Environmental Impact
Statement drafted. The parties could not agree on a final routing, so the Federal Highway
Administration attempted to withdraw from the project. A lawsuit by trafficway opponents successfully
resulted in an injunction that suspended any construction activity until the SEIS was completed. The
lack of consensus remained, and the final SEIS was published with a "no action" decision to remove
the court injunctions. Soon afterward, KDOT started the process on a new EIS, with a 32nd Street
alignment, approximately 1/8 mile south of 31st, and relocating 31st off of the Haskell right of way,
as well as a more extensive mitigation proposal for the Baker Wetlands than previously discussed. The
Final EIS, released in early 2003, approves the 32nd Street alignment. It was subsequently adopted by
the Federal Highway Administration in February 2008. Opponents to the 32nd Street alignment, led by
the Prairie Band Pottawatomie tribe, filed a suit against the Federal Highway Administration and KDOT
challenging that the 2003 EIS was biased toward the 32nd Street alternative, that an alignment
suggested by the tribe had been improperly rejected, the noise study was done incorrectly, and that
the cost of the 32nd Street alternative was under-estimated. The US District Court ruled in November
2010 that the noise study was not properly done, and that the cost of the 32nd Street alignment was
under-estimated; however, the court also rejected the allegation of bias and the tribe's suggestion
had been properly considered and rejected, ultimately finding in favor of the FHwA and KDOT. The
plaintiffs filed an appeal of the ruling in April 2011. Part of the mitigation area on the west side
of the existing wetlands was completed in 2010. Funding for completion of the SLT was announced on
June 3, 2011. No timeline for completion of the SLT has been established.
