Construction has been suspended until Spring 2020. Cycling restrictions have been lifted. The roadway remains in a construction-related alignment in two sections, so it is not at it’s intended full-width. Please use caution when traveling through the canyon.
Introduction/Background
Background:
In September 2013, flood waters either damaged or destroyed approximately 1.5 miles of two sections of Fourmile Canyon Drive between Boulder Canyon Drive and Salina Junction. The lower portion (south section) starts about 1-mile up from Boulder Canyon Drive and extends to Poorman Road, and the upper portion (north section) starts near Logan Mill Road and extends up to Salina Junction. The projects to repair Logan Mill Road/Bridge, Upper Fourmile Canyon & Gold Run Road are separate from this project.

90% Complete Plan Set for Roadway Work – Uploaded March 9, 2017
This plan set has been broken into smaller pieces to make the files easier to open. The files below include both the north and south sections of lower Fourmile Canyon Drive (Hwy 119 to Salina Junction). These plans will continue to be revised as we work with impacted property owners.
- Pages 1 to 34 – Title Sheet, Symbols, Notes, Typicals, Quantities, Tabulations, Survey Control, Key Map, and Geometric Layout
- Pages 35 to 50 – Removals & Resets
- Pages 51 to 79 – Tree Inventory*
- *NOTE – The tree inventory is still being updated and do not depict the actual tree figures. We’re also working on contract language that will require the contractor to save as many trees as possible. While it is unlikely we will be able to prevent all tree removals, we will ensure that only those tree that are absolutely necessary will be removed.There will also be a large revegetation effort at the end of the project.
