I-270 Advocacy Initiative

Celebrating the Makeover of the I-270 North Project

I-270 expansion project in North St. Louis County.
The MoDOT's I-270 team did a great job keeping this project on track, even during COVID. NCI thanks them for their hard work and focus to bring this project in on time and on budget.

In December 2023, North County Incorporated (NCI) leaders joined Missouri Governor Mike Parson and state and local elected officials, along with the Missouri Department of Transportation and its contractor team, Millstone Weber, to cut the ribbon on this four-year-long makeover of more than nine miles of interstate in north St. Louis County. The completion of the $278 million I-270 North Project was celebrated with an official ceremony in Hazelwood.

“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.

In 2006, NCI prioritized I-270 as a critical transportation corridor needing major infrastructure improvements in North St. Louis County and began advocating for transportation officials to do so too. NCI developed a collaborative partnership of business, civic, and community leaders to steadily work to bring this positive investment to fruition.   

“I want to thank our many partners who stood strong with NCI throughout the past decade and a half, consistently lending their voices to the importance of this project and keeping it at the forefront of the transportation decision-makers to ensure that this major infrastructure improvement project receives the attention and funding necessary to increase multi-modal safety and access throughout this critical transportation corridor,” said Rebecca Zoll, President and CEO of NCI.   

Construction on the I-270 North Project began in April 2020. North County Incorporated, the four municipalities along I-270, St. Louis County, Metro Transit, and countless businesses joined 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.

The 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 project demonstrates the power of speaking in one powerful voice about what is important in our community and the successes that come out of that type of collaboration,” said Zoll.
