From keeping traffic moving during major freeway construction to improving neighborhood streets, transit access and storm response, Scottsdale’s Transportation & Infrastructure Department delivered a wide range of projects and services in 2025 that strengthened safety, accessibility and mobility across the city.

“Transportation and Infrastructure touches residents’ lives every day, whether it’s the condition of our streets, how traffic flows during major events or how quickly crews respond after a storm,” said City Manager Greg Caton. “The work completed in 2025 reflects a strong commitment to planning ahead, coordinating across departments and delivering reliable service.”

Transportation and Infrastructure Sr. Director Alison Tymkiw said the department’s success is rooted in collaboration and careful planning across multiple disciplines.

“Our teams are constantly coordinating behind the scenes to minimize disruptions while delivering long-term improvements,” Tymkiw said. “In 2025, that teamwork allowed us to complete complex projects, respond quickly to resident needs and continue investing in infrastructure that makes Scottsdale safer and more accessible for everyone.”

Supporting regional mobility and major projects

Transportation & Infrastructure teams worked closely with the Arizona Department of Transportation to complete the Loop 101 Improvement Project, a collaboration that spanned nearly two years. Traffic engineering staff approved construction phasing and restrictions to minimize impacts to drivers and major events such as the WM Phoenix Open, while the city’s Traffic Management Center monitored conditions and adjusted signal timing near closures.

Communications staff shared weekly construction updates with city staff and residents, including advance notice of full freeway and ramp closures. Transportation planners supported project design, managed the intergovernmental agreement with ADOT and oversaw landscaping and the restoration of The Path Most Traveled public art installation in partnership with Scottsdale Arts.

Traffic safety, lighting and utility protection

Traffic Engineering utility locate teams responded to more than 18,900 requests through the city’s 811 program in 2025, maintaining a 100% accuracy rate to protect critical infrastructure and improve jobsite safety.

Streetlight crews also upgraded more than 780 damaged or end-of-life fixtures to energy-efficient LED lighting, improving visibility while reducing long-term maintenance and energy costs.

Expanded trolley service and community access

Scottsdale Trolley ridership continued to grow in 2025, with Spring Training game-day service to Scottsdale Stadium increasing by 70%. The growth followed the introduction of a new route, improved signage and enhanced marketing, including wrapped trolley vehicles and marquee displays.

The trolley also launched a pilot program with Human Services to provide free Thursday-morning service to Scottsdale’s expanded food bank facility, improving access to essential services for residents.

Planning for safer, more connected streets

Transportation Planning led several initiatives that promote active transportation and long-term investment. Scottsdale celebrated Valley Bike Month by highlighting its designation as a Gold-Level Bicycle Friendly Community, hosting events such as Cycle the Arts and Bike to Work Day and showcasing the city’s paths and trails system at the Tour de Scottsdale expo.

The team also secured $17.3 million in federal funding for the Thomas Road Reconstruction and Improvement Project between 56th and 73rd streets. Now in design, the project will evaluate roadway repair options and upgrade aging water and sewer infrastructure beneath the street.

Preserving pavement and improving accessibility

Pavement preservation crews installed more than 730 ADA-compliant curb ramps in 2025, expanding access citywide. Since 2020, the city has installed or upgraded more than 4,200 ramps, with much of the work coordinated alongside scheduled repaving projects and funded by local transportation sales tax.

Crews also completed minor street preservation treatment to extend pavement life and improve surface appearance. During the fall paving season, more than 820,000 square yards of roadway received treatment across neighborhoods and Old Town.

As part of the Old Town Pavement Improvement Project, the city resurfaced streets, alleys and parking lots on an accelerated schedule, completing more than 367,700 square yards of improvements in just over two months through close coordination among crews, contractors and communications staff.

Street operations and rapid response

The city’s Emergency Response Team, made up of staff from Transportation & Infrastructure, Parks and Recreation and Facilities, responded to an average of more than one callout per day in 2025, clearing fallen trees and debris after storms to keep roads and sidewalks safe.

Street Operations also completed cleanup after four major storm events, removing an estimated 16,000 square yards of sediment while meeting county air quality requirements. Crews supported WestWorld’s busy horse show season by assisting with event changeovers, cutting preparation time from three days to about 30 hours.

Engineering and capital project delivery

In-house design and project engineering teams completed or advanced dozens of capital improvement projects in 2025, supporting water resources, transportation, drainage, parks and public safety facilities. Major accomplishments included infrastructure improvements along Indian Bend Wash, intersection upgrades on Shea Boulevard, completion of Fire Station 612, new park amenities and continued construction of the Water Quality Lab Building.

Together, these efforts deliver infrastructure that supports Scottsdale’s quality of life today and into the future.
