The section between Page and Olive (tentatively titled the Page-Olive Connector), which was constructed by St. Louis County has been turned over to the Missouri Department of Transportation and designated as Route 141. Maryland Heights Expressway (the section from Page north to I-70) and Earth City Expressway (the section from I-70 north to its terminus at Route 370) have also been designated as 141. As such, Route 141 now runs from US 61/67 in Arnold to Route 370 in Bridgeton.

DHT held studies of the environment to decide how to maneuver construction without disturbing some of the native wetlands in the corridor. During heavy rain, the current intersection at Creve Coeur Mill Road and Olive has the potential to flood, and most of the area along Creve Coeur Mill Road are either wetlands or farmland that lies in a flood plain.

Highway 141 was a two-lane road built in the 1930s. The idea of an newer, divided highway carrying the Route 141 designation dates to the 1970s, when regional highway planners adopted the idea of an "outer belt" west of I-270. In 1976, Frank Kriz, then the district state highway engineer, called
