2009 Construction Projects

• Westbound I-44 over the Meramec River – Bridge rehabilitation at the Meramec River bridge west of Lewis Road. Project should start in fall 2008.
• I-270 ramp project at Rte. 364 (Page Ave.) - Design work is under way for a project to construct a new ramp from northbound I-270 to westbound Rte. 364. This would help alleviate congestion at the interchange, especially during evening rush hour. The interchange is not designed to handle current traffic volumes. Construction is expected to start in summer 2009. Funding for this project was approved by the East-West Gateway Council of Governments in July 2005. The estimated cost for construction is $26 million. This project will also include work on I-270 at Marine. For more information visit the Rte. 364 & I-270 Interchange Improvements page.

Future Projects

• Rte. 141 Project between Ladue and Olive Blvd. This project is currently not funded. The current preferred alignment would construct Rte. 141 as a six-lane road east of existing Route 141 and would also add two through lanes in each direction along Route 141 between Ladue Road and I-64/Rte. 40. A single point urban interchange is proposed at Olive Boulevard and a single point diamond interchange is proposed at Ladue Road. This project is in MoDOT's long-range plan for 2011 to 2020.
