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.
The project went into winter suspension on Jan. 11. Minor work will continue in the project area during the winter suspension. Any traffic impacts are expected to be minimal. We will post an update once regular construction work resumes.
A significant portion of the construction work is expected to be completed by February 2021. Minor work will continue through February 2022. This schedule could be impacted by the winter suspension.
About the Project
Canyon Road East from 96th Street East to 84th Street East will be widened to five lanes, with two through lanes in each direction and a two-way left-turn lane. This section will have paved shoulders, curbs, gutters, and sidewalks. Canyon Road East from 99th Street Court East to 96th Street East will be widened to four lanes, with two through lanes in each direction. This section will have paved shoulders and barrier curbs on the west side, and curbs, gutters, and sidewalks on the east side. A new traffic signal will be added at the Canyon Road East and 96th Street East intersection. The Canyon Road East and 84th Street East intersection will be widened, and a reconstructed traffic signal system was activated to accommodate the future configuration.
Street lighting, an enclosed storm drain system, and stormwater storage and treatment facilities will be added as part of the project.
Utility relocation work began in 2019 and was completed in June. East side of project
Construction work began on the east side of the project, with crews clearing the project site through mid-May. Work to install storm drainage facilities ran from mid-May to late August. A 35-foot-long retaining wall has been built about 200 feet east of the Canyon Road East and 84th Street East intersection. Crews installed traffic signal system infrastructure from late July to late October. Curbs and gutters were installed from early September to early October. Paving work took place in early October. Work to install curb ramps started in November and was completed in December. Work to install sidewalks started in November, with minimal work possible during winter suspension. Work to install street lights began in December, with minimal work possible during winter suspension. West side of project
Work shifted to the west side of the project in mid-October. Crews installed drainage facilities, street lights, traffic signal system infrastructure, curbs, gutters and sidewalks through the end of 2020. Additional work on street lights and traffic signal system infrastructure is possible during winter suspension.
A reconstructed traffic signal system at the Canyon Road East and 84th Street East intersection was activated on Dec. 9. The new traffic signal system at the Canyon Road East and 96th Street East intersection is expected to be activated in 2021.
Some paving work took place in December. The work is expected to resume in the spring. The road will be restriped into the new configuration once paving is complete. Paving work is weather dependent. Landscaping maintenance is expected to run through February 2022.
