Southwestern Oklahoma US-62 enters Oklahoma in
Harmon County, west of
Hollis. It then passes through that town, the
county seat, where it serves as the southern terminus of
State Highway 30. US-62 meets the northern terminus of
SH-5 in
Gould. The highway passes through unincorporated
McQueen later. US-62 serves as the southern terminus of the northern
State Highway 54 east of this. The road then enters
Comanche County, where it serves as the southern border of
Fort Sill. It serves as the southern terminus of another Oklahoma state highway,
SH-115, near
Cache. A few miles of the highway east of SH-115 is freeway-grade. Continuing east, US-62 becomes an expressway, Rogers Lane, that serves the north side of
Lawton (along with several Ft. Sill gates). In eastern Lawton, the highway has an interchange with
Interstate 44 and begins a concurrency with it (joining at Exit 40B), along with
US-277 and
US-281. I-44/US-62/277/281 head northward through Fort Sill. At Exit 45, the freeway serves as the eastern terminus of
State Highway 49. The three U.S. routes split off at Exit 46, with I-44 continuing onto the northern section of the
H. E. Bailey Turnpike. US-277 splits off to the east later. US-62/281 then meet
SH-19 in
Apache.
SH-9 begins overlapping the two U.S. routes north of Apache. The three routes continue into
Anadarko, where
State Highway 8 briefly joins the concurrency. US-283 and SH-8 split off to the north, while US-62/SH-9 head out of town to the east.
Central Oklahoma US-62/SH-9 cross into
Grady County just west of
Verden. At the western limits of
Chickasha,
US-81 joins the concurrency. In downtown Chickasha, US-81 splits off to the south, and US-277 once again joins with US-62. In far eastern Chickasha, the routes have an interchange with I-44 (the H.E. Bailey Turnpike). US-62/277/SH-9 serve as the southern terminus of
SH-92 and the western terminus of
SH-39. The three highways then angle northeast towards
Blanchard, where they are briefly joined by
State Highway 76. Northeast of Blanchard, they are carried by an expressway. SH-9 splits off at a
diamond interchange that also serves as the eastern terminus of the H.E. Bailey Turnpike Spur. The two U.S. routes continue north into
Newcastle, running through town on a five-lane (two lanes in each direction plus center turn lane) alignment. On the northern rim of Newcastle, the two routes encounter I-44 once again, at the northern terminus of the Bailey Turnpike. US-62 joins eastbound I-44 toward Oklahoma City, while US-277 terminates at the interchange. I-44/US-62 pick up
State Highway 37 at Exit 107, and the three highways cross the
Canadian River into
Cleveland County and
Oklahoma City. SH-37 then splits off at Exit 110. Just north of the
Oklahoma County line, I-44 has an interchange at the western terminus of
Interstate 240 at Exit 115, and US-62 follows it east to Exit 4B, where it begins to concur with
I-35/
US-77. I-35/US-62/77 head northward to the
Fort Smith Junction. US-77 splits off to join with
Interstate 235, while I-35/US-77 join with eastbound
I-40/
US-270. I-35/US-62 split off to the north after just over a mile. US-62 leaves I-35 at Exit 130, turning east onto N.E. 23rd St., an at-grade street US-62 serves some of Oklahoma City's eastern suburbs, including far northern
Midwest City, far southern
Spencer,
Nicoma Park, and
Choctaw. In eastern
Harrah, the route meets the west terminus of
State Highway 270. The highway then crosses into far southern
Lincoln County, where it crosses
SH-120 at
Midway. US-62 runs through two more unincorporated communities,
Fowler and
Jacktown; the latter is the site of the US-62/
US-177 junction. US-62 enters
Meeker later, where it meets up with
SH-18. further east, in
Prague, it encounters
US-377/
SH-99.
Green Country US-62 enters eastern Oklahoma's
Green Country as it crosses into
Okfuskee County west of
Paden. It begins to turn southeast, intersecting
State Highway 48 west of
Castle, before joining once again with I-40 near
Okemah, at Exit 221.
US-75 also joins the interstate, farther east at Exit 231. The two U.S. routes split off at Exit 240B, where they continue the mainline of the
Indian Nation Turnpike, which terminates at I-40. The two U.S. routes serve eastern
Henryetta, and west of
Dewar, they are the western terminus of
U.S. Highway 266. In
Okmulgee, US-62 turns east while US-75 continues north toward the
Tulsa area. US-62 heads through
Morris, where it intersects
SH-52. The highway then has a overlap with
SH-72, after which it begins a concurrency with
US-64. US-62/64 split up in
Muskogee, where US-62 briefly overlaps with
US-69. On the east side of town, it has an interchange with the
Muskogee Turnpike/
SH-165 freeway. Near
Ft. Gibson, US-62 begins to concur with
State Highway 10, and the two routes stay joined through
Tahlequah. US-62 starts to overlap
State Highway 51 in Tahlequah as well; the two highways split up near
Eldon. The route enters
Adair County near
Proctor. It intersects with
US-59 in
Westville before US-62 crosses the state line into Arkansas. ==History==
