Powering Urban Infrastructure: Lessons from the Tucson 22nd Street Bridge & Roadway Project

Infrastructure Demands: The Tucson Bridge Replacement

The selection of Granite Construction for the 22nd Street widening project in Tucson, Arizona, highlights a growing global trend: the urgent need to modernize aging urban infrastructure. This specific project is centered around replacing a 60-year-old bridge with a new, wider structure to accommodate increased traffic. For contractors, projects of this magnitude represent a high-stakes environment where equipment downtime is not an option.

Bridge Demolition: The SM150/30G Advantage

A core phase of any widening project is the demolition of existing concrete structures. Bridge decks and reinforced piers require a breaker that can deliver consistent, high-impact energy without overheating.

Our SM150/30G Hydraulic Breaker (a technical equivalent to the HB30G) is purpose-built for these heavy-duty tasks. With its 150mm chisel diameter and vacuum heat-treated alloy steel components, the SM150 provides the striking force necessary to penetrate high-density reinforced concrete. In projects like the Tucson widening, using an SM150 series breaker ensures that demolition stays ahead of schedule, providing a clean slate for the new construction phases.

Efficiency in Tool Switching: The SLK100 Quick Hitch

Infrastructure work often requires a single excavator to perform multiple roles—breaking concrete one hour and digging utility trenches the next. This is where the SLK100 Hydraulic Quick Hitch becomes an essential asset.

As seen in major U.S. roadworks, the ability to switch from a breaker to a bucket in under 30 seconds significantly reduces labor costs. The SLK100’s double-safety lock system ensures that these transitions are not only fast but safe, meeting the rigorous safety standards required by firms like Granite Construction and municipal departments of transportation.

Supporting Global Urbanization

Whether it is a multi-million dollar bridge in Arizona or a road expansion in Southeast Asia, the fundamentals of successful infrastructure remain the same: precision, safety, and durability. SLYM Machinery continues to support the world’s builders by providing excavator attachments that bridge the gap between ambitious engineering designs and ground-level execution.
