The Route 141 improvement project improved safety and traffic flow, prevents flooding and reduces congestion along Route 141 between Olive Boulevard (Route 340) and Ladue Road (Route AB).
In 2009, the Missouri Highway and Transportation commission approved $65 million to complete work on the Route 141 Improvement Project between Ladue Road and Olive Blvd. MoDOT broke ground for the relocated Route 141 project in west St. Louis county on March 15, 2010.
MoDOT worked closely with St. Louis County and Maryland Heights on their project to complete the Page-Olive Connector to ensure the two projects worked together. MoDOT has allocated money from its share of money from the American Recovery and Reinvestment Act for the Route 141 project. East-West Gateway Council of Governments has programmed approximately $20 million for St. Louis County to complete work on the Page-Olive Connector project.
What is the Problem With Route 141 Between Ladue and Olive?
There were three major problems with Route 141 between Olive and Ladue: congestion, safety, and flooding. Route 141 was built in the 1930s and could not handle current traffic. More than 23,000 cars a day use this t stretch of roadway, and several intersections are highly congested. Traffic levels over the next 20 years are expected to increase by up to 35 percent in some locations. Accident rates have risen to nearly double the statewide average, and the road typically floods several times a year.
What is the Proposed Solution?
The current design will construct Route 141 to the east of its current location and turn the current Route 141 into an extension of Old Woods Mill Road. Designers are planning for a six-lane road east of existing Route 141 with two through lanes in each direction along Route 141 between Ladue Road and I-64/Route 40. Drivers will access the relocated Route 141 at interchanges at Olive Boulevard and Ladue Road.
