Two-Month High Line Canal Trail Closure Starts Monday, Oct. 30 for Drainage Work

DOUGLAS COUNTY—Starting Monday, Oct. 30 and continuing for two months, CDOT will close the High Line Canal Trail as crews complete drainage work for the C-470 Express Lanes project. During construction, there will be street and sidewalk detours.

Notifications concerning the full closure will be provided separately once details are determined.

At 71 miles long, the High Line Canal Trail has approximately 500,000 annual users, extends across 11 jurisdictions, and intersects with 98 streets. A total of 350,000 people live within one mile of the trail.

Trail users should be cautious and watch for signage to guide them as they ride or walk through the construction areas. Construction work is weather dependent and subject to change.

Should a motorist's vehicle become disabled on C-470, courtesy patrol will be provided at no cost to the driver from 6-9 a.m. and from 3:30-6:30 p.m., Monday through Friday.

More than 100,000 motorists currently use this segment of C-470 each day, with volumes projected to increase 40 percent by 2035. Construction is scheduled for completion in spring 2019.

Project Info

The $276 million C-470 Express Lanes project will increase mobility and user choice along 12.5 miles between I-25 and Wadsworth Boulevard. Crews will add two Express Lanes on westbound C-470, from I-25 to Colorado Boulevard, and one Express Lane from Colorado Boulevard to Wadsworth. They also will add an Express Lane on eastbound C-470, between I-25 and Wadsworth Boulevard.

Crews will fully reconstruct existing pavement; add auxiliary lanes at selected locations; improve on- and off-ramps; realign substandard curves; widen existing bridges; replace the bridges over the South Platte River; install tolling equipment; and build new C-470 trail underpasses at Colorado and Quebec.

When complete, the improvements will give motorists the option of using the Express Lanes on C-470 for a faster, more reliable commute in exchange for paying a toll. Or, they may drive the general purpose lanes for free.
