October 16, 2018 – The Big Cottonwood Bike Trail that runs through Knudsen Park in Holladay, Utah has re-opened. The trail section by 6200 S and Holladay Boulevard was closed for construction of the 6-acre new park. The new public park will, according to the park's website, have a new playground, picnic facilities, and walking paths and “will also serve as a bicycle hub for the local and regional bicycle network, providing restrooms, water fill-up facilities, and bike repair stations.” The park is scheduled to be open in May 2019.
The Big Cottonwood Trail is approximately 2 miles and extends from 6200 S and Holladay Boulevard to the mouth of Big Cottonwood Canyon and runs along Big Cottonwood Creek and Big Cottonwood Canyon Road to the west of the mouth of the canyon in the Old Mill area.
