Construction Update on the Olive/Lindbergh Boulevard Interchange

Olive Lindbergh Interchange

Construction has begun on the Olive and Lindbergh interchange reconfiguration project to turn the existing cloverleaf interchange into a folded diamond interchange, which will move commuter traffic more efficiently and offer full connectivity for cars, bikes and pedestrians.

Ramp Closures and Detours

The two cloverleaf ramps on the south side of Olive will remain closed through the fall:

  1. Eastbound Olive to Northbound Lindbergh – Drivers on Olive will pass Lindbergh and continue east to Old Olive, where they will turn left and continue on to Lindbergh.
  2. Southbound Lindbergh to Eastbound Olive – Drivers will need to exit Lindbergh at Old Olive before getting to Olive, then they can follow Old Olive to Olive and turn east (left) onto Olive.

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.
