Improvements to Centennial Greenway at Interstate I-170 and Delmar Coming Soon!Posted on August 22, 2018August 24, 2018 Great River Greenway Announces: We are getting ready to break ground on improvements to the Centennial Greenway at Delmar and I-170 that will make the intersection easier for people to navigate whether they are walking, riding a bike or driving a car.Construction is expected to begin in early September and continue through the end of November (weather permitting). There will be temporary lane restrictions or closures along Delmar and McKnight during this time, but the intersection and the sidewalks will remain open. Construction work will generally take place on weekdays, Monday through Friday, between the hours of 7am and 3pm.As the project progresses, there will be some temporary impacts to the greenway. We will place signage along the greenway to let people know about any potential closures. We will also post updates on our website, Facebook and Twitter.When construction is complete, there will be enhanced crosswalks, ADA compliant sidewalks, upgraded traffic signals and new way-finding signage that will allow everyone to more safely walk, run, push a stroller, use a wheelchair or ride a bike from Shaw Park to Olive Blvd.
