Missouri State Highway 30 is a highway in eastern Missouri. Its eastern terminus is at the
Interstate 55/
Interstate 44 junction in
St. Louis. Its western terminus is at
Interstate 44 in
St. Clair. In St. Louis, the section between Interstate 44 and
Missouri State Highway 366 is part of historic
U.S. Highway 66 and is marked as such. In the St. Louis area, it is known as Gravois Avenue or Gravois Road. Further south, Gravois Road is used to mark the old section of the highway where the newer, divided highway rerouted Highway 30.
Missouri State Highway 30 begins as it crosses over Interstate 55 at I-55's interchange with I-44. The four-lane road turns southwest as Gravois Road and, after about two miles, intersects Missouri 366. Shortly after the intersection with Missouri 366, the road becomes a narrow street passing through some older parts of St. Louis. At the city limits of St. Louis, it continues into the suburban area (unincorporated). Shortly before reaching Grantwood Village is the northern terminus with
Missouri State Highway 21. About two miles further west is the intersection with Lindbergh Boulevard (
US 61/
US 67/
US 50 and the road becomes a four-lane divided highway. A mile past Lindbergh Boulevard is the junction with
I-270, and two miles southwest of that is an interchange over
Missouri State Highway 141.
As the highway continues southwest in the suburban St. Louis area, the road has several traffic lights which gradually diminish as the road approaches
Cedar Hill. West of Cedar Hill, the divided highway ends and the road becomes a winding road all the way to its end.
West of
Lonedell is the beginning of a
concurrency with
Missouri State Highway 47. The concurrency ends five miles later inside the city limits of St. Clair. The road briefly joins former
U.S. Route 66, turns a corner, and ends at Interstate 44.
