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.

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
