St. Louis — The completion of the $278 million I-270 North Project was celebrated with an official ceremony today in Hazelwood. Missouri Governor Mike Parson joined state and local elected officials along with the Missouri Department of Transportation and its contractor team to cut the ribbon on this four-year long makeover of more than nine miles of interstate in north St. Louis County.

"The I-270 North Project demonstrates the success we can achieve when government, private industries and local communities invest in transportation infrastructure to ensure Missourians have safe roads and bridges to travel to work, take their kids to school and transport their goods and services," said Missouri Governor Mike Parson. "This project also invested in our youth and the workforce of tomorrow through a STEM program, which included more than 100 local high school students interested in construction and engineering careers. This is a great example of our infrastructure and workforce development efforts working together for the betterment of our communities."

Construction on the I-270 North Project began in April 2020. The four municipalities along I-270, St. Louis County, Metro transit and countless businesses have worked together to work through the design and construction challenges to complete this project on time and on budget.

"This project not only improves the daily commute of the 140,000 cars and trucks that use I-270, but it elevates this interstate as a major conduit for the state's economy as a freight corridor connecting to manufacturers, suppliers and distributors along Interstate 70," said MoDOT Director Patrick McKenna. "The updates significantly improve the communities and reconnect people's lives along the highway with the addition of improving the highway and its interchanges and outer roads, creating 10 miles of multi-use path and other pedestrian facilities, and building the first dedicated bus lane connecting the North County Transit Center to the St. Louis Community College."

The I-270 North Project improvements include:

  • Reconstructed interchanges at North Lindbergh (Route 67), Hanley/Graham, New Florissant (Route N), Washington/Elizabeth, West Florissant, New Halls Ferry, Old Halls Ferry, and Lewis and Clark (Route 367)
  • Additional driving lane in both directions on I-270 from North Lindbergh (Route 67) to Lewis and Clark (Route 367)
  • Improved accessibility for bicyclists and pedestrians with a multi-use path from Lindbergh (Route 67) 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
  • Signal updates and replacements
  • New and replaced bridges
