Interstate 44 (I-44) in the US state ofMissouri runs northeast from theOklahoma state line nearJoplin toI-70 inDowntown St. Louis. It runs for about 293 miles (472 km) in the state, and is the longestInterstate Highway in the state.

I-44 enters Missouri inNewton County at the eastern terminus of theWill Rogers Turnpike, 200 yards (180 m) south of theKansas state line. The first interchange in Missouri is the eastern terminus of bothU.S. Route 166 (US 166) andUS 400. This highway next goes through southernJoplin and then begins torun concurrently withI-49/US 71 at exit 11 just after enteringJasper County. The freeway turns to a more eastern heading (the old route of US 166), and then I-49/US 71 splits off to the north at exit 18.
I-44 next entersLawrence County. NearMount Vernon, the highway curves to the northeast. The section of highway toHalltown is a completely new highway, not supplanting any previous highways. At Halltown, the road curves back to due east, beginning to follow the general pathway of oldUS 66, which it does all the way to downtown St. Louis. I-44 then goes around the western and northern sides ofSpringfield, serving as the western terminus of theJames River Freeway, as well as crossing bothRoute 13 andUS 65. The Interstate Highway continues northeast, bypassingLebanon.
InPulaski County, I-44 enters theMark Twain National Forest and then leaves it to provide access toWaynesville,St. Robert, andFort Leonard Wood before reentering the national forest. The freeway leaves the forest inPhelps County west ofRolla. I-44 then goes through Rolla, where it meetsUS 63. It continues its northeastern course, passing nearSt. James,Cuba,Bourbon,Sullivan, andSaint Clair. At this point, it roughly parallels theMeramec River.

I-44 next goes north ofPacific before moving intoSt. Louis County. I-44 then bisectsEureka before serving as the southern boundary ofRoute 66 State Park (the former site ofTimes Beach, known for itsdioxin contamination and its eventual demolition andSuperfund cleanup[citation needed]). I-44 then runs across unincorporated land before enteringFenton and meeting an interchange withI-270 inSunset Hills. I-44 then goes throughCrestwood,Kirkwood,Oakland,Webster Groves, andShrewsbury before entering the city ofSt. Louis. I-44 runs on a due east course through St. Louis until it meetsI-55 south of downtown. The two highways run concurrently for about two miles (3.2 km) until I-55 turns east at an interchange withI-64 to cross theMississippi River on thePoplar Street Bridge. I-44 then continues north throughDowntown St. Louis on the former route ofI-70 to its junction with that highway at theStan Musial Veterans Memorial Bridge; drivers wishing to access eastbound I-70 must cross the Poplar Street Bridge via I-55 and I-64.

I-44 follows the general route of, and completely replaced, historicUS 66 fromHalltown (exit 58, the junction with a cutoff section of US 66 since renumbered asRoute 96) to downtown St. Louis. From ruralJoplin at exit 15 toMount Vernon at exit 49, it largely follows adecommissioned section ofUS 166.
Originally, the eastern terminus of I-44 was at theI-55,I-64,I-70, andUS 40 interchange by thePoplar Street Bridge. This was changed when theStan Musial Veterans Memorial Bridge opened on February 9, 2014, rerouting I-70 over the river along a more northern alignment. I-44 now takes the old I-70 alignment through the below-grade section of roadway in St. Louis, extending the Interstate for about 1.5 miles (2.4 km) to its new eastern terminus at a directional interchange with I-70 near Cass Avenue;[2] the eastbound lanes of I-44 join the westbound lanes of I-70, and the westbound lanes of I-44 branch off the eastbound lanes of I-70.[2]
Missouri Department of Transportation (MoDot) has proposed to improve I-44 across Missouri such as an additional lane and some curve realignment. Study is known as Forward I-44.[3]

All of I-44'sbusiness routes are in Missouri. Most of these business loops were the formerUS 66. Missouri also has the unusual occurrence of a business loop and business spur from the same Interstate intersecting (the Waynesville–St. Robert loop and the Ft. Leonard Wood spur).
