Drivers on most-traveled roads in Arizona to get new, improved freeways

T

Drivers will temporarily encounter construction delays but ultimately end with longer, wider freeways and other improvements to some of the most traveled roads in Arizona under a five-year plan from the Arizona Department of Transportation.

Building the South Mountain Freeway in the southeast Valley and improving roads near Tucson, Scottsdale, Wickenburg, northern Arizona and along the Mexico border are part of a $4.5 billion construction plan. Some projects will start as soon as this year.

The high-priority projects will ease traffic woes, add jobs and spur other economic development, said Laura Douglas, ADOT spokeswoman.

Other key road projects include:

  • Completing two I-10 projects that will complete a goal of widening the entire stretch of I-10 from Casa Grande to Tucson to a six-lane divided highway.
  • Improving State Route 189 in Nogales to help commerce between Interstate 19 and the port of entry.
  • Adding a railroad overpass on State Route 347 in Maricopa.

  1. Did somebody in our transportation department forget about public transit? Building more, and ever more roads seems to be a leading industry, probably second to residential/commercial construction. Moreover, it is clear that there is a hunger among residents for transport other than the automobile (or, in selected venues the ubiquitous pickup truck). The added vehicle count will only worsen ozone and other issues and add to
    the heat halo.
    Time for some creative thinking beyond the well connected contractor/government contract.
