Construction is scheduled to be completed by the end of the year. This project is funded by $4 million of federal transportation funding to design and construct the new interchange, a $1 million match from St. Louis County Transportation and $300,000 of funding from the City of Creve Coeur.
The Olive and Lindbergh interchange reconfiguration is one of the significant transformative projects planned to implement the bold vision of the 39 North Innovation District, a 600-acre global hub for plant and life sciences located in Creve Coeur.
