Final configuration

What was done as a part of the I-270 North project

The I-270 North Project made multiple improvements along Interstate 270 from I-70 to just west of the Riverview interchange in North St. Louis County. The project:

  • Reconstructed interchanges at North Lindbergh, Hanley/Graham, New Florissant, Washington/Elizabeth, West Florissant, New Halls Ferry, Old Halls Ferry, and Lewis and Clark.
  • Build an additional driving lane in both directions on I-270 from North Lindbergh to Lewis and Clark.
  • Improved accessibility for bicyclists and pedestrians with a multi-use path from Lindbergh to Breezy Point along Dunn, and from Hanley/Graham to Old Halls Ferry along Pershall.
  • Improved safety with an updated outer road system that includes removal of all cross over slip ramps
  • Updated or replaced signals.
  • Constructed or replaced bridges along the corridor.
