US 93 widened to four lanes north of Wikieup

PHOENIX – The Arizona Department of Transportation has finished converting three miles of US 93 north of Wikieup to a four-lane divided highway increasing safety and traffic capacity.

The upgrade to a four-lane divided highway improves traffic flow, supports the movement of freight and enhances safety through this heavily traveled corridor.

This project connects two sections of highway that had already been widened. This provides a continuous stretch of divided four-lane highway from milepost 108, about 15 miles south of I-40, and milepost 121 near Wikieup.

The majority of the 200-mile drive from Wickenburg to the Nevada state line has been widened. Fewer than 40 miles of US 93 remain a two-lane highway.

Work on the $35 million project began in the spring of 2019. In addition to converting US 93 into a four-lane divided highway, the project included building concrete box culverts, two box bridges and installing pipe culverts, guardrail and fencing. 

Crews plan to return in the spring to add a top layer of pavement, known as friction course, to the newly-widened segment.
