Boonville business loop Interstate 70 Business (
I-70 Bus.) is a
business loop of
I-70 in
Boonville. It runs from exit 101 on I-70, taking the overlap with
US 40 with it and also overlapping
Route 5. I-70 Bus./US 40/Route 5 run northeast, where it intersects both Old Highway 40 and Sombart Road, the latter of which serves as a connection to the
Santa Fe Trail. As it passes by Frederick T. Kemper Park, the routes curve to the east and approaches
Route 87 (Main Street), where US 40/Route 5 turns left at a northbound overlap while I-70 Bus. turns south at a southbound overlap, until both routes turn southeast onto Bingham Road and Main Street becomes "Highway B". The further the road gets away from Boonville, the more chances the suburban settings give way to rural and agricultural ones. Aside from the western terminus of
Route 98, the only other site is the Hail Ridge Golf Course and a local street leading to
Jesse Viertel Memorial Airport. I-70 Bus. ends in
Windsor Place at exit 106 on I-70, while Route 87 continues south toward
Eldon.
Columbia business loop Interstate 70 Business (
I-70 Bus.) is a
business loop of I-70 in
Columbia between exits 125 and 128. On July 9, 2018, the onramp connecting the business loop to eastbound I-70 was disconnected. There is now no direct way of access to eastbound I-70 via eastbound I-70 Bus. The
Missouri Department of Transportation is now considering the removal of the westbound I-70 Bus. exit ramp. If this proposal is approved, the only direct access to the business loop from I-70 would be at exit 125.
St. Charles business loop Interstate 70 Business (
I-70 Bus.) is a
business loop of
I-70 in
St. Charles. It runs from exit 228 to 229, partially along
Route 94, as well as otherwise unmarked First Capitol Drive and Fifth Street. I-70 Bus. begins at exit 228, a
single-point urban interchange with Route 94 (First Capitol Drive) and turns north, immediately having an unconventional interchange with Boone's Lick Road. From there, it passes by a city water tower just south of West Clay Street. As it runs past
Lindenwood University, I-70 Bus./Route 94 curves around a former segment of First Capitol Drive, then reencounters that road as I-70 Bus. makes a sharp right turn to the east while Route 94 continues to the northeast along Kings Highway. First Capitol Drive runs at a straight line toward Riverside Drive and the
Katy Trail State Park along the
Missouri River, but I-70 Bus. does not go that far. Instead, it makes a sharp right turn at South Fifth Street, which becomes North Fifth Street two blocks north of this intersection. South Fifth Street is four lanes wide with a center left-turn lane for one block but narrows down to two lanes between Jackson and Tompkins streets, only to widen again south of McDonough Street. The route becomes a divided highway before the intersection with Boone's Lick Road, and the last intersection along the route is Bass Pro Drive and Ameristar Boulevard. I-70 Bus. ends at exit 229 as it loops into a partial cloverleaf interchange with I-70, just before that road crosses a bridge over the Missouri River. ==Ohio==
