Business Loop I-70 - Columbia

With the exception of a 0.193 mile overlap with Route 763 between Rangeline Street north and College Avenue south, Business Loop I-70 is a locally maintained route following old U.S. 40 for 2.80 miles. The marked route runs east from Exit 125 to a wye interchange (Exit 128) by the freeway along U.S. 63.

The city of Columbia signs this stretch of old U.S. 40 as "Business Loop 70," even though it is also known as Mores Boulevard. Moreover, the city naming extends west from Exit 125 to Stadium Boulevard, north of the I-70 DDI at Exit 124.
