Hayden and Thomas Intersection Improvements

The City of Scottsdale is currently designing a series of modifications to the intersection of Thomas and Hayden roads to improve the safety of the intersection. The proposed improvements are on Thomas Road only and include construction of raised medians, modified left turn lanes for improved visibility, a dedicated right turn lane, a reduction of access points to the intersection, and pedestrian safety improvements.

Why are the improvements needed at the intersection of Thomas Road and Hayden Road?

The intersection of Hayden and Thomas roads has a collision rate of more than double the citywide average and has been in the “top 6” for number of collisions citywide for the last 10 years.

Year Rank by # Rank by Rate # of Collisions Collision Rate City Average
2014 4 2 32 1.61 0.57
2012 1 1 40 1.82 0.52
2010 6 15 25 1.07 0.48
2008 4 7 32 1.33 0.53
2006 1 1 50 2.24 0.57
2004 1 3 53 2.33 0.64

Note that the intersection is:

  • Top 6 in number of collisions 2004-2014.
  • Highest number of collisions in three of six study years.
  • Top three in collision rate in four of six study years.
  • Collision rate more than double citywide average.
  • 2009 - Listed in the Arizona Top Five Percent in number of collisions.
  • 2009 - Ranked 11th in Maricopa County in a report of the top 100 intersections from 2006-2008.

What is the City doing to improve the situation?

The purpose of this project is to increase vehicle, pedestrian and bicycle safety by improving traffic control and pedestrian facilities.  

Proposed changes include:

  • A raised center median along Thomas Road
  • Off-set, left-turn striping eastbound and westbound at Hayden Road and Thomas Road
  • An improved westbound right-turn lane on Thomas Road
  • A new eastbound right turn lane on Thomas Road
  • Dedicated bus bays along Thomas Road
