is a business spur of I-70 along U.S. Route 50 (US 50)/US 89 in Salina, running north from exit 56 for 1.8 miles (2.9 km) until terminating at the end of the US 50/US 89 overlap.

It was suggested in 1979 but rejected by the American Association of State Highway and Transportation Officials (AASHTO), who opted for US 40 Bus.

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.

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.

ends in Windsor Place at exit 106 on I-70, while Route 87 continues south toward Eldon.

It runs from exit 228 to 229, partially along Route 94, as well as otherwise unmarked First Capitol Drive and Fifth Street.

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.

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.

It ran from exit 47 at the east end of the State Route 4 (SR 40) overlap onto an expressway.

The route made an easterly turn before crossing a bridge over a railroad line, then encountered a west-to-southbound only flyunder interchange with Lower Valley Pike shortly before another westbound only flyunder interchange with US 40, where the expressway ended.

The route became a one-way pair after Bechtle Avenue, with the eastbound lanes moving to Columbia Street.

Continuing to pass through downtown Springfield, the routes were joined by SR 41 at North Yellow Springs Street.

SR 4 left the concurrency remaining on Columbia Street, when the one-way pair ended at an interchange for Lagonda Avenue, then turned southeast on another brief limited-access segment which ended as it rejoined Main Street at an at-grade interchange that included North and South Greenmount avenues.

East of South Fostoria Avenue, I-70 Bus./US 40 ran over another bridge over a railroad line, then widened to a four-lane divided highway with a wider grassy median.
