The Arizona Department of Transportation has been working for more than 40 years to improve US 60 between Interstate 10 in Tempe and Superior. The most recent project, completed in 2008, extended the divided highway from Florence Junction through Gonzales Pass to Queen Creek, near the Boyce Thompson Arboretum.
This $32.8 million project will continue the improvement of US 60 from Queen Creek through Superior to the junction of State Route 177. The divided highway will be extended to the western boundary of Superior at approximately Silver King Road, and the roadway will be improved through Superior. Preparations for the construction have been completed, and the contractor will start Sept. 14.
Work started on the west side of the project by the Boyce Thompson Arboretum in September 2015 where crews began constructing the new two-lane divided highway to match the current divided highway. The new divided highway will be constructed north of the current highway and will tie back into the current highway close to the Superior airport. Workers have been concentrating their work north of the existing highway, but they are planning to start moving construction activities into Superior early spring 2016.
There is currently another construction project on the east side of Superior (US 60 Oak Flat Passing Lane) where there are delays due to blasting. ADOT is working with that contractor and the new contractor for the Silver King / Superior Streets project to coordinate their work to have the least impact on traffic as possible. This coordination will continue as both projects progress.
This page will be updated with the latest information about the project as the project progresses.
