Construction & Detours

Updated February 2018

Notice of temporary Greenway closure and a good story about cooperation: Monday, February 19, our Sand Creek Greenway will be closed at the Central Park Blvd bridge going over the trail from 8 pm to 5 am, in order to start construction on a new bridge. Representatives from Denver Parks and RecreationMortensen Construction, Inc. Kraemer North America and our Sand Creek Regional Greenway Partnership met yesterday to form a plan to accommodate construction schedule needs, but limit impact to trail users and to the riparian areas near the bridge. The end result to trail users: the trail will be closed for (very) limited number of nights starting at 8 pm over a several month period, and these nights will be posted on trail signs and on social media. (so stay tuned) This will avoid lengthy and unattractive trail detours during that time. In addition, there may be very short delays of less than 10 minutes during very limited periods. This will protect trail users, while keeping the Greenway open as much as possible. The first overnight trail closure is Monday, February 19, starting at 8 pm.

We thank our friends and partners at Denver Parks and Recreation, and new friends at Mortenson Construction and Kraemer North America for their cooperation on this important matter. We know our Greenway is a place for recreation, but it is also a way many of you get to work each day. Knowing ahead of time is critical for you. By working together, we can get this new bridge built and keep our Greenway open! Thanks to all for this great cooperative effort!

About the Greenway

The Sand Creek Regional Greenway is a jewel in the necklace of trails that has made Denver a national model for linked trail systems.

This 14-mile public greenway connects the High Line Canal in Aurora, Colorado with the South Platte River Greenway in Commerce City. Along the way, it passes through northeast Denver and the new Stapleton community.

The Sand Creek Regional Greenway is open every day from dawn until dusk. Runners, walkers, nature viewers, horseback riders, and leashed dogs are encouraged to enjoy the trail. We invite you to become acquainted with our wilderness in the city.
