Recommended Build Alternative - I-17: Anthem Way to Sunset Point

Anthem Way TI to Black Canyon City TI (MP 245): The Recommended Build Alternative includes adding a lane in both directions, widening the northbound roadway toward the median side and widening the southbound roadway toward the median in some segments and toward the outside in other segments.

Black Canyon City TI to Sunset Point TI: The Recommended Build Alternative includes constructing two flex lanes next to but separated from the southbound roadway by a concrete barrier. The flex lanes would be open to either northbound or southbound traffic depending on the peak traffic direction. Access to the flex lanes would be controlled by gates or a similar mechanism.
