Construction & Detours

December 2018

Our friends at Mortenson alerted us that during the week of December 10, there will be some construction under Peoria at the border between Aurora and Denver on our Greenway to install a storm main. This is the area affected. Mortenson tells us the trail will not be closed during this time, and will provide a way for bicyclists and other trail users to get around the construction.


November 2018

As the Martin Luther King Blvd project moves into high gear, there’s good news for long-term improvement of our Greenway between Bluff Lake Nature Center and the border (under Peoria Ave.) between Denver and Aurora. Here’s a summary of the work to be done, from Mortenson.

In addition
Our friends at Mortenson alerted us there may be construction activity on the Denver portion of the Greenway on November 12, as they repair some limited areas of trail surface near the Central Park Blvd bridge.  The trail will NOT be closed, but it may be flagged and there may be very minor detours while work is taking place.

July 2018

Another alert for the Central Park Blvd bridge area in the Denver portion of our Greenway. We were informed that a concrete pump set up on the trail on 7/16/18 under the bridge deck at Central Park Blvd and the Greenway.  The pump will be in place from 2:00am – 2:00pm.  Flaggers will be on site stopping trail users until it is safe for them to cross.

Thanks to our friends at Mortenson for advance notice of this trail delay!

June 2018


AURORA: (June 1) we just heard of a closure at Airport Road, the result of utility work, and we’re trying to learn more about this and how long the trail might be closed. Stay tuned and check our social media channels for updates.

UPDATE: 6/5/2018, from Aurora Parks and Open Space

“Aurora Water is installing bypass pipe so they can re-line the sewer line from Colfax to Airport through the Sand Creek corridor.  Sewer line is north and east of trail.  Closures should be temporary (i.e. less than an hour).  They will have a flagger to help trail users get by while they bury pipe under the trail.  Their bypass starts at a manhole on the south side of Colfax east of the drive into the trailhead site.  You may see some pipe laying there for a day or two before they start connecting it.  From that manhole, the line will run west under the bridge over Sand Creek and then north along the trail.”


DENVER: Notice from our friends at Mortenson, regarding the area around Central Park Blvd bridge:

June 4-8

The sidewalks leading to the bridge will be closed down 8:00am – 4:00pm Monday – Friday.  From Mortenson: “Whenever we need to shutdown Smith Rd to do safety critical work, we also have to shut down the sidewalks. There are detours posted with the road closure signs but attached is a map that they can use.”

June 10

UPDATE: As of 6/7/18, this closure has been cancelled. Our Greenway trail under the bridge on the north side of the creek will be closed,  June 10 8:00pm – 5:00am.  From Mortenson: “Kraemer will be removing the crane pad dirt on the north side of the bridge. They will need to close down the trail that night.”

June 2

The western stretch of our Sand Creek Greenway in Commerce City is now paved and fully open! Landscaping work will continue in that area, but the trail is open and it is beautiful! Hearty thanks to our friends in the Parks and Recreation Department of Commerce City for their vision and hard work making this important enhancement to the Sand Creek Greenway. Now it is even easier getting to the South Platte!

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. 



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!

Drainage/Diversion Structure Work

Map of affected area, please note: our trail is misnamed as “Colorado Front Range Trail” in this image.




Starting 4/9 for about a month in Denver, there will be trucks near the trail–but not blocking the trail–south of I-70 and east of Quebec. Work will begin on two “diversion structures,” commonly known as manholes or drainage structures. Insituform will be performing work on the drainage structures in the area.

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.
