Route 141, also known as Woods Mill Road in parts of St. Louis County,
Route description
For the majority of its duration, Route 141 is a divided highway with four to eight lanes.[2]
Jefferson County
In
St. Louis County
Route 141 enters St. Louis County in Fenton. It has an interchange with Route 30 and widens into a six- to eight-lane divided highway. Heading north, Route 141 passes a plaza to the left that includes various restaurants. After the plaza, Route 141 heads into a suburban area and has at-grade interchanges with several collector roads. The highway heads northeast and has an interchange with Interstate 44 in Valley Park. Shortly after this interchange, Route 141 crosses the Meramec River and the Meramec River Greenway and enters Valley Park.[2]
In Valley Park, Route 141 passes over, and then under, a pair of
Past the intersection, Route 141 serves as a border between
Past this point, Route 141 becomes a controlled-access freeway. It has a SPUI with Ladue Road (Route AB).[2] The highway curves northeastwards, passing Parkway Central High School, which is located to the west of the road. Shortly after passing the school, Route 141 curves back northward and heads through a wooded area. Subsequently, Route 141 as a SPUI interchange with Route 340 (Olive Boulevard). Route 141 becomes elevated after the interchange, crossing over Creve Coeur Creek and several other streams, and passing a neighborhood to the west.[2] Route 141 then crosses Waterworks Road and railroad tracks, entering Maryland Heights. The name of the road changes to Maryland Heights Expressway. Shortly after entering Maryland Heights, Route 141 has a SPUI with Route 364, After that, Route 141 passes Hollywood Casino Amphitheatre, and has an interchange with Interstate 70, and the highway splits between north and southbound and reconnecting at Route 180 (St Charles Rock Road) [2]
The highway meets its northern terminus after the interchange with Route 370 at Missouri Bottom Road.[1]
History
Old 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.
Extension
In August 2012, a six-lane realignment opened between Ladue Road and Page Avenue (Route 364), with interchanges at Ladue, Olive (Route 340), and Page. 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.
The Missouri Department of Transportation (MoDOT) in cooperation with the St. Louis County Department of Highways and Traffic (DHT) expanded Route 141. 1 between just south of Ladue Road (Route AB) to Olive Boulevard (Route 340). DHT extended Route 141 from Olive Boulevard to the Page Avenue Extension (Route 364) at the Maryland Heights Expressway which links to the Earth City Expressway which continues north to
St. Louis County Executive Charlie Dooley had called the project "one of St. Louis County's largest and most important infrastructure improvements this decade." The economic impact of the construction project was not nearly as massive as the upgrading and realignment project on Interstate 64/Highway 40. This construction project was estimated to have a $20 billion economic impact and create over 170,000 jobs during the 2010 decade.[5]
