State Highway 99 (Oklahoma)
Encyclopedia
State Highway 99, also referred to as SH-99 or OK-99, is a north–south state highway through central Oklahoma
. It runs from the Texas
border at Lake Texoma
to the Kansas
border near Lake Hulah. It is 241.5 miles (388.7 km) long. The highway overlaps US-377 for over half its length.
SH-99 links up with K-99
after crossing the border into Kansas. This road continues for 233 miles (375 km) to the Nebraska border, where it becomes Nebraska Highway 99
, which lasts an additional 14 miles (22.5 km). Thus, SH-99 is part of a triple-state highway numbered "99", which lasts a total of 488 miles (785.4 km).
State Highway 99 began as State Highway 48, a short highway connecting Ada
to Holdenville
. This highway was gradually expanded until it became a border-to-border route. In 1938, it was renumbered to match K-99, which was renumbered from K-11 the same day.
on a bridge from Grayson County, Texas
into Marshall County, Oklahoma
. This is the southern terminus of SH-99, which will concur
with US-377 all the way to the U.S. highway's northern terminus in Stroud
. The highways' first junction in Oklahoma is with State Highway 32
7 miles (11.3 km) south of Madill. Five miles north of this intersection, US-377/SH-99 serve as the northern terminus for SH-99C, a child route of SH-99. The routes then head into Madill, where they form a brief concurrency with US-70 and SH-199. US-377/SH-99 head northeast out of town and enter Johnston County
.
West of Tishomingo
, US-377/SH-99 pick up SH-22, which follows them east to the county seat. The same junction in Tishomingo where SH-22 splits away is also the northern terminus of SH-78. Eight miles (12.9 km) north of Tishomingo, the routes share a short concurrency with SH-7. US-377/SH-99 go 18 miles (29 km) without another highway junction, which is with SH-99A, a spur to unincorporated Harden City.
The two highways interchange with SH-3, a freeway at this point, near Ahloso. US-377/SH-99 merge onto the freeway, which becomes the Richardson Loop around the west side of Ada
. At the southwest corner of the loop, SH-1 joins. Two miles (3.2 km) further north, an interchange serves as the western terminus of SH-19; also at this interchange, SH-3 splits into SH-3E and SH-3W, the latter of which exits the highway to concur with SH-19. At the next interchange, SH-1 splits off, and the freeway downgrades to expressway.
The highway crosses the Canadian River
into Seminole County
north of Byng
. Just after the bridge, US-377/SH-3E/99 intersect SH-39 and SH-56; this is their eastern and western termini respectively. Near Bowlegs
, SH-59 joins the concurrency, splitting off again after 3 miles (4.8 km). As the road enters Seminole
, it has an interchange with US-270, where SH-3E splits off. SH-9 also is accessible by interchange in Seminole. US-377/SH-99 encounter another spur of the latter, SH-99A, in unincorporated Little. The routes then have an interchange at I-40, Exit 200.
US-377/SH-99 cross over the North Canadian River
and cross a panhandle of Pottawatomie County
before entering Lincoln County
. Just north of the county line, the routes pass through Prague
. The two routes do not encounter another highway for 19 miles (30.6 km), after which lies the town of Stroud
, the northern terminus of US-377.
. An interchange with Interstate 44
, the Turner Turnpike
, is 0.4 mile (0.643736 km) north of the SH-66 junction.
Signage in Stroud is unclear on where the northern terminus of US-377 is, implying that it continues north of SH-66 to at least I-44. However, signage along the turnpike and at the end of the offramps only refers to SH-99.
ODOT sources differ on where the northern terminus of the highway is. According to the Control Section Map Book, the north end of US-377 is at SH-66. Another map published by ODOT of Stroud implies that the route extends north of the ramps to and from I-44 to at least the bridge over the turnpike. The inset strip map of the Turner Turnpike on the ODOT state map omits US-377 entirely.
, which it overlaps for two miles (3 km) to the town of Drumright
. SH-99 bypasses Drumright to the northwest, after which it meets up with an old alignment leading back to Drumright and SH-33, now numbered SH-99B but unsigned. After turning back north, it crosses the Cimarron River at Oilton
, and has an interchange with the Cimarron Turnpike
between Jennings
and Hallett
.
It is then concurrent with US-64 for six miles (10 km) before passing through Cleveland
, where it crosses the Arkansas River
. Throughout its final 55 miles (88.5 km), in Osage County
, the highway passes through a relatively sparse region, though it meets State Highway 20
in Hominy
and overlaps SH-11
south of Pawhuska
(the county seat) and US-60 north of the city. Its final junction is with SH-10
ten miles (16 km) south of the Oklahoma–Kansas border.
; it roughly followed present-day SH-99 until just north of the Canadian River
, after which it turned east on the route of today's SH-56. The highway ended at the original SH-3, present-day US-270, west of Holdenville. The 1928 state highway map shows the highway extended to SH-9 (now US-62) near Prague along the present-day SH-99 alignment, with the Canadian River crossing as a toll bridge. By January 1, 1929, the route had been realigned to pass through Konawa
.
In 1931, SH-48 was greatly expanded. The route was extended northward to US-66
in Stroud. At its southern end, it was extended along a new alignment, which began at SH-19 southeast of Ada and ran through Tishomingo and Madill to end at the Red River northwest of Denison, Texas
, where it met Texas State Highway 91. Also that year, a second section of SH-48 was established, taking over a large portion of what was then SH-25; the remainder of the route was integrated into US-60.
On March 1, 1932, a new section of road was designated as State Highway 48, connecting Stroud to SH-33 west of Drumright. As a result, the SH-48 designation was able to follow existing roads to link up with its previously-disconnected northern section. Thus, SH-48 became a border-to-border highway, linking Texas and its SH-91 to K-11 at the Kansas state line.
In January 1944, Denison Dam
was placed into operation, creating Lake Texoma
. As a result, a portion of SH-99 between Madill and Texas was inundated. On May 5, 1958, the route was realigned to once again reach Texas; it now crossed a bridge further upstream, connecting to Texas State Highway 10, which was subsequently renumbered to TX-99.
The existing route of SH-99 (concurrent with SH-3) veered west by about 4 miles (6.4 km) to serve the town of Konawa
before cutting back northeast to continue the highway's previous heading. This was remedied on December 9, 1968, when the highway was changed to a straighter alignment bypassing Konawa. The old road heading west into Konawa became part of SH-39.
Another bypass occurred in 1977, this time in Drumright. SH-99 was changed to bypass the town on February 7, 1977, and the old alignment that was not part of SH-33 became SH-99B. However, the highway remained signed along SH-33 through Drumright until at least 2003.
system several times. One such application made in 1953 suggested that the entirety of SH-99 become a U.S. Route, while another suggested a northern terminus at US-64 near Cleveland. On June 18, 1964, AASHTO accepted an extension of US-377 from Texas to US-70 in Madill. The Department of Highways, and later the Department of Transportation, submitted an application to extend US-377 from Madill to US-64 in Cleveland eight times between December 1964 and 1980.
In 1991, ODOT signed the route to Stroud along SH-99 without AASHTO approval.

, where it met Texas State Highway 91. Also that year, a second section of SH-48 was established, taking over a large portion of what was then SH-25; the remainder of the route was integrated into US-60.
On March 1, 1932, a new section of road was designated as State Highway 48, connecting Stroud to SH-33 west of Drumright. As a result, the SH-48 designation was able to follow existing roads to link up with its previously-disconnected northern section. Thus, SH-48 became a border-to-border highway, linking Texas and its SH-91 to K-11 at the Kansas state line.
Renumbering and realignments
On May 17, 1938, both Kansas and Oklahoma renumbered K-11 and OK-48 respectively to bear the number "99", providing continuity between the states. At this time, SH-99 followed the same basic corridor of the present-day route from Madill north to Kansas. The SH-48 designation would only remain disused for just under three years, resurfacing for a route only 13 miles (20.9 km) east of SH-99 in February 1941.In January 1944, Denison Dam

On June 18, 1964, AASHTO accepted an extension of US-377 from Texas to US-70 in Madill.
