Mandatory Takeout at Placer Flats/Mile 260.5

Currently, all construction traffic enters the construction site at the junction of State Highway 119 & US Highway 6.  As construction moves downstream and further away from this point, it gets increasingly more difficult to back vehicles in and out. To provide alternate entry/exit points, in the coming weeks the first of multiple temporary river crossings will be installed at the area known as “Cannonball Flats.”  These crossings will be made of conjoined concrete culverts and WILL BE IMPASSABLE for rafters, kayakers and all other river users.  All river activities must take out at the “Placer Flats” takeout, also known as “Mile 260.5.”  This is the takeout after the bridge at the intersection of State Highway 119 & US Highway 6 and after the Class III rapid known as “Whew!”.  Please see the flyer below for more detailed information.  If you have further questions please contact the Public Information Team at 303.569.9972 or

Peaks to Plains Trail

One Boulder at a Time

How is the Peaks to Plains Trail being constructed? Often, as you’ll see in the videos and pictures below, it’s one boulder at a time.

Despite the wet spring and high water, construction of the Peaks to Plains Trail is well underway. This is a really exciting time for both counties as many years of hard work have taken place to get to this point. After months of revising plans, and hours going over designs, we are finally getting a feel for what the trail corridor looks like. While we are eager to move construction along as quickly as possible, the counties have tasked the construction team with taking a surgical approach to construction. This is no easy task in a steep, rocky canyon environment. As such, the team is working slowly and methodically to keep the construction corridor narrow. This allows minimal impact on the native vegetation and enables us to save as many trees as possible.
