St. Vrain Greenway Reopens at Sandstone Ranch

by Jennifer Loper06/29/2018 10:30 AM
Updated: 12/02/2019
The St. Vrain Greenway between County Line Trailhead and the Sandstone Ranch Visitors Center has reopened for public use. The trail was destroyed in the 2013 flood that severely damaged much of Longmont.

Restoration of this portion of the greenway was completed as part of the first phase of Longmont’s Resilient St. Vrain Project (RSVP), an extensive, multi-year undertaking to restore the St. Vrain Greenway and improve the St. Vrain Creek channel to protect people and property from future flooding.

Bicyclists and pedestrians planning to travel the trail are reminded that no dogs are allowed on this portion of the St. Vrain Greenway. City Council directed this restriction to protect this unique landscape and its important wildlife habitats.

Much work was completed during the closure. In addition to rebuilding the trail, creek banks were stabilized to provide protection from future flooding. Nearly 200,000 native plants also were added to help re-establish wetlands habitat for fish and wildlife.

A temporary closure to this portion of the St. Vrain Greenway is anticipated later this summer when an existing oil and gas well located very near the trail will be plugged and abandoned by the well owner, TOP Operating. That closure is anticipated to last for several weeks, during which time the public will see large rigging equipment on the site. Signs will be posted notifying users of the closure once a date is set.

St. Vrain Greenway Status Update

Users can see current trail sections open across Longmont and get details on closures at

  • A July reopening is anticipated for the St. Vrain Greenway between the Left Hand Greenway and Main Street (RSVP City Reach 1). After reopening, this portion may experience periodic closures as construction begins on Dickens Farm Nature Area.
  • A detour, including some on-road portions, are in place surrounding the South Pratt Parkway Bridge replacement. This detour is clearly marked to help users cross South Pratt Parkway on Boston Avenue. This detour will be extended along Boston to Coffman Street later this summer after a pedestrian bridge crossing St. Vrain Creek east of the Pratt bridge is removed for construction.
  • This fall, Resilient St. Vrain work will require closure of the greenway between Main Street and the BNSF Railroad Bridge (at Price Road). A detour route will be clearly marked with signs and on-road striping where appropriate.
  • The St. Vrain Creek waterway remains closed to public access between South Pratt Parkway to 119th Street, per City order issued in May 2017. (This is basically from Budget Home Center on the west to the Sugar Mill on the east.) Activities prohibited by the closure order include fishing, tubing and general creek access.This closure is for public safety during construction in and near the creek.
