Canyon Road East - 99th Street Court East to 84th Street East (CRP 5726)
Construction on a project to enhance safety and relieve traffic congestion on Canyon Road East between 99th Street Court East and 84th Street East began April 8.
Crews will work 7 a.m. to 5:30 p.m. Monday to Thursday. The road may be periodically reduced to one lane with alternating traffic between 8:30 a.m. and 3 p.m.
A significant portion of the construction work is expected to be completed by February 2021. Minor work will continue through February 2022. If a winter suspension is needed due to weather, this schedule could be impacted.
