Its total length is about 4.5 miles (7.2 km) and no incorporated towns are on the highway. It is locally named Marceau Street, Alabama Avenue and Lemay Ferry Road.
Route 267 begins at an intersection with US 50/US 61/US 67 in Mehlville, St. Louis County, heading northeast on four-lane divided Lemay Ferry Road. The road continues past this intersection as part of US 61/US 67. From the southern terminus, the route heads through business areas, becoming a five-lane road with a center left-turn lane. Route 267 loses the center turn lane and continues through suburban areas of homes and commercial establishments. The road gains a median as it heads into more urban areas of residences and businesses before narrowing into a two-lane undivided road. Farther northeast, the route crosses River des Peres into St. Louis and becomes Alabama Avenue. A short distance later, Route 267 turns southeast onto four-lane divided Marceau Street and passes through residential areas. The route comes to its northern terminus at an intersection with Broadway.
