The blue line is where the next upgrades in 2021 will be.

As Phoenix drivers head for Flagstaff during the summer, traffic frequently grinds to a standstill on Interstate 17.

The Arizona Department of Transportation hopes to end those backups.

ADOT has begun negotiations with a design company that will oversee improvements on 23 miles of the freeway between Anthem Way and Sunset Point.

That section can see more than 50,000 drivers a day and is where many of the backups take place.

The project will widen the road and a number of bridges.

It will also install an eight-mile flex lane system to reduce congestion during peak travel times.

The work is expected to take about three to three and a half years.
