History

I-44 follows the general route of, and completely replaced, historic US 66 from Halltown (exit 58, the junction with a cutoff section of US 66 since renumbered as Route 96) to downtown St. Louis. From rural Joplin at exit 15 to

interchange by the Poplar Street Bridge. This was changed when the Stan 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 to its new eastern terminus at a directional interchange with I-70 near Cass Avenue; 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.

Future

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.

Business loops

All of I-44's business routes are in Missouri. Most of these business loops were the former US 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).
