The expansion, located near Signal Butte and Elliot roads, adds 1.5 miles of LED-lit walking trails, three ramadas and additional biking trails alongside the pump track — a circuit of rolling bumps and banked turns that riders navigate by pumping their bodies up and down rather than pedaling. The design lets riders build speed through body movement alone, making it accessible to a range of skill levels.

The project was financed through a bond Mesa voters approved in 2018, a detail city officials highlighted as evidence of the community's investment in public spaces.

"Thank you to our voters for supporting these improvements and investing in the parks and amenities that make our city a great place to live, work and raise a family," Mayor Mark Freeman said in a statement.

Vice Mayor Scott Somers framed the park as a response to the area's rapid growth, saying the city needs more outdoor options as its population expands.

"As our community grows, we need more places where people can get outside, stay active and spend time together," Somers said.

The expansion reflects a broader push in Mesa and across the East Valley to add recreational infrastructure as development spreads outward. The LED-lit trails extend usable hours into the evening, while the pump track offers a low-cost, car-free activity for young riders — a draw for families in a fast-growing corridor.

The opening comes as Mesa continues to invest in parks and amenities funded by the 2018 bond, which voters approved to support a range of city improvements. City officials said the Signal Butte project is part of that commitment to keeping public spaces in step with residential growth.

The park is now open to the public.
