Thornton continually strives to have one of the best trail systems in the North Metro area and along with this occasionally comes the need for improvements. Two sections are currently under construction and closed to the public until the beginning of December, 2020. The trails involved are the Eastlake #2 Trail and the Villages North Trail. A few adjoining trail segments are also closed, and detour signage is posted. Please refer to the accompanying image or visit gocot.net/cipmaps for details.
