PRESCOTT – The Arizona Department of Transportation launched a new project this week to widen US 93, the primary travel route for Phoenix drivers headed to Las Vegas, and efforts continue on another ongoing widening project to further a decades-long commitment to convert the rural two-lane roadway to a modern, four-lane divided highway in northwest Arizona.

Just north of Wickenburg, ADOT started this week on the expansion of US 93 between State Route 71 and State Route 89 (mileposts 185-190). The $12.5 million project, reconstructing the highway into four lanes, is expected to be completed in 2016.

This project will be funded through the Federal Highway Administration’s Highway Safety Improvement Program.

Along this section of highway, ADOT previously installed a centerline rumble strip, which is a pattern of small cuts in the pavement, in an effort to alert drivers whose vehicles cross the centerline of the two-lane, two-way roadway. Signs were also added to remind drivers that US 93 has two-way traffic and ADOT made it a requirement that drivers use their headlights during daylight hours.
