Reach 2 Projects

Reach 2 extends from the eastern corporate limits of the City of Longmont, west to Airport Road. This reach includes Longmont proper and is a heavily populated portion of the St. Vrain. The City of Longmont was among the hardest hit communities during the catastrophic flooding event in September 2014. Damages to city infrastructure, in excess of $148M, included significant damages to parks and trails along the St. Vrain corridor. A number of homes were flooded at the western edge of the reach and numerous bridges and culverts were damaged by floodwaters and debris.

City Reach
The City of Longmont is also managing the projects in the City Reach, which runs through urban, developed areas of Longmont from the Left Hand Creek confluence to Airport Road. Construction for City Reach 1, from Left Hand to Main St., is anticipated to begin in February 2017 (read an article about that work here) . The 30% design for City Reach 2, from Sunset St. to Main Street, has been completed. The Main Street Bridge replacement is on track to be completed in early 2017.

  • Main Street to Left Hand Creek (east of Martin Street) – This area includes the Main Street Bridge, which is being replaced and slated to be completed in December 2016. The project was out to bid in mid-October, with construction slated to begin in November.
  • Boston Avenue to Main Street – The City of Longmont will be accepting bids on this reach late in November, to be awarded by the first of the year.
  • Roger’s Grove Park to Boston Avenue – Sunset Street Bridge has already been replaced and is open! The bridge was completed in the summer of 2016.
  • Lykins Gulch to Roger’s Grove Park
  • Airport Road to Lykins Gulch
