All are welcome to attend

A ribbon cutting ceremony will be held to commemorate the completion of another major Boulder County Transportation flood recovery-related construction project. County Commissioners, Transportation staff, and members of the project team will be on hand to celebrate this amazing undertaking. Members of the public are invited to attend and speak if they'd like. 

Project Background:

Boulder County has completed designs on improvements to the intersection of Four Mile Canyon Drive and Gold Run Road at Salina Junction. The 2013 Flood washed out much of the intersection and collapsed an existing 48” metal culvert that was meant to carry Gold Run across the intersection during storm events.

The repairs will replace the washed out culvert with a larger structure that is better able to carry large storm events; prevent damage to both roadways; and better maintain traffic through the intersection both during and after a major flood. Installing a larger culvert at the site will require widening out the existing Gold Run channel upstream of the intersection and removing some of the rock that is currently constraining flood waters through the site. Work is anticipated to begin in early January 2016 and last through the spring of 2016, weather depending. A project rendering is depicted below:
