The Arizona Department of Transportation and the Federal Highway Administration are scheduled to begin the project to reconstruct the traffic interchanges on Interstate 17 at Happy Valley and Pinnacle Peak roads, add an additional travel lane on I-17 and replace a box culvert on Pinnacle Peak Road. The purposes of the project are to improve safety and traffic flow as population growth and development in this area of north Phoenix continue to grow.
Construction at both interchange locations is occurring within existing ADOT right-of-way. ADOT does not need to acquire any additional property.
Travel will be impacted while construction is underway. ADOT will share information about specific lane restrictions or closures as it becomes available.
