I-635 begins atI-35 inJohnson County nearShawnee, Kansas, at exit 1A. There is aparclo interchange with Merriam Drive at exit 1B almost immediately after its terminus. It then entersWyandotte County andKansas City, Kansas. There is a diamond interchange with Shawnee Drive at exit 1C and a parclo interchange with Metropolitan Avenue at exit 1A upon entering theArgentine neighborhood. There is an interchange withK-32/Kansas Avenue at exit 3 and then crosses theKansas River into central Kansas City, Kansas. Immediately after crossing the river, there is an interchange withI-70 at exits 4A and 4B. There are several interchanges further north, including State Avenue (exit 5), Parallel Parkway (exit 6), and Leavenworth Road and North 38th Street (exit 7). The last public interchange before enteringMissouri isK-5. A private maintenance facility crossing at grade exists between this exit and the Missouri River.
LikeI-435, I-635's mileposts do not reset after crossing into Missouri.
I-635 crosses the Missouri River from Kansas intoPlatte County and the city ofRiverside, Missouri. There is an interchange with Horizons Parkway at exit 9 and thenUS 69 at exit 10. US 69 briefly runs concurrently with I-635 north before exiting at the interchange withRoute 9 (exits 11A and 11B). I-635 runs about one more mile north, then terminates atI-29/US 71 at exits 12A and 12B.
Missouri began the plans for I-635 in 1958 whenAmerican Association of State Highway and Transportation Officials (AASHTO) approved proposals that also included what would becomeI-435 andI-470; the plan for I-635 took the route eastward along what is nowK-5 toUS 69 and northward across theFairfax Bridge towardI-29.[2] When money from theHighway Trust Fund became available for a new Missouri River crossing, I-635 got a more westward alignment after 1968.[2] Part of the original alignment was built as a spur going into Fairfax asK-5.[3]
In 1990, the highway was given the nameHarry Darby Memorial Highway, in honor of US SenatorHarry Darby.[4][5][6]
The interchange withI-70 and the bridge over theSanta Fe Railyard inArgentine were reconstructed in 2004.[7]
Maintenance work on the bridge over theMissouri River finished in September 2005.[citation needed]
