Scottsdale will move forward with several transportation projects after the City Council approved on consent a construction bid award and a budget transfer for the Hayden and Thomas roads intersection.

AJP Electric was the lowest bidder for the award with a unit price of $2,433,648.75. The city will also make a Capital Improvement Plan of $1.6 million from the Miller Road Underpass at Arizona State Route 101 project to the Hayden/Thomas Safety Improvements project, which the transportation 0.2 percent sales tax will fund.

The proposed improvements will only be on Thomas Road and will include raised medians, dual left turn lanes with positive offsets, dedicated right turn lane, access point consolidation and pedestrian safety improvements.

City staff say they identified savings in the Miller Road Underpass project that will help fund the Hayden/Thomas Safety Improvements project since the available funding will not cover the required cost.

These savings are available because the Arizona Department of Transportation bid this project with a larger freeway project and the part the city was responsible for ended up being lower than anticipated.

The city says portions of this project will be eligible for reimbursement from the Highway Safety Improvement Program from the Federal Highway Administration.

City staff say if the project is delayed, the city would forfeit federal funding.

City staff cited a 2009 ranking from the Maricopa Association of Governments that put the intersection as 11th on its list of high crash intersections in the county. The city also cited a 2009 State of Arizona Top 5 Percent Report stating the intersection needed safety repairs.

Furthermore, a recent Scottsdale Independent analysis of dangerous roads yielded that Hayden Road, from Thomas Road to Osborn Road, had 54 collisions in 2015 and 2016. This put it eighth on a list of dangerous stretches of road in Scottsdale.

In 2011, the Federal Highway Administration approved the intersection’s application for an Intersection Safety Improvement grant. The city followed that up with an engineering services contract with Ritoch-Powell to perform design services to prepare a project assessment.

That assessment yielded three alternatives but the city ultimately put the project on hold because of high costs of the project.

In 2015, the city approved a contract with Ritoch-Powell and Associates to provide design serves for the production of construction documents for the CIP project.
