[Job Story] Liebherr LR 1300.1 SX Cranes Support Juneau Creek Bridge Project in Alaska

Two LR 1300.1 SX crawler cranes are supporting Traylor Bros. on one of Alaska’s major bridge and roadway projects, where terrain, access and environmental constraints leave little room for error.

Building a major bridge in Alaska is a test of logistics, planning and machine reliability in terrain where access is limited, and weather, topography and distance can turn every operation into a critical path activity.

That is the setting for the Juneau Creek Bridge near Cooper Landing, a 951 ft (290 m) structure that will form part of a wider two-phase multi-bridge and roadway project on the Kenai Peninsula. Designed to improve traffic flow and safety around Cooper Landing, the project is taking shape in a remote mountain landscape with the support of two Liebherr LR 1300.1 SX crawler cranes operated by Traylor Bros., Inc.

Cooper Landing has fewer than 300 residents, but its summer tourism season brings a sharp increase in visitors, especially for fishing and outdoor recreation. That seasonal pressure can heavily affect traffic through the town. The new roadway and bridge alignment is intended to reroute vehicles more efficiently and safely around the community.

On site, the challenge is not only the size of the bridge but the way it is being assembled. Traylor Bros. is using the bridge launch technique, assembling steel girders on one side of the canyon before gradually pushing the structure across Juneau Creek Canyon with hydraulic presses. The method allows large bridge sections to be positioned without the need for complex scaffolding across the chasm.

The Liebherr LR 1300.1 SX cranes are being used for critical lifts throughout the assembly process. In this environment, lifting operations must be coordinated around steep slopes, limited access roads, staged steel sections and sensitive surrounding habitats.

“It starts with having a good crew, many of whom are used to working in remote Alaska”

Said Tyler Becker, senior field engineer for Traylor Bros., Inc. He noted that a project of this scale requires close coordination between multiple parties, particularly when moving and operating large equipment such as crawler cranes in a remote location.

The LR 1300.1 SX is designed with self-assembly and self-loading capability, features that are particularly valuable where transport routes and site space are constrained. The crane also includes assistance systems intended to support safer and more efficient operation, as well as a cab designed for operator comfort and service availability in demanding locations.

For Traylor Bros., familiarity with the model was also part of the decision:

“We have several LR 1300 machines across the company, so there is company-wide familiarity with the machine. Additionally, it’s simply the right tool for the job – versatile with the capacity needed for all lifts on the site. Having the right tool for the job is incredibly important for safety and efficiency. This crane works when we need it and does what we ask of it.”

Becker said.

Operator feedback has also highlighted the importance of Liebherr’s Gradient Travel Aid system. According to Travis Ludlow, operator for Traylor Bros., the feature was especially useful on the Juneau Creek site. The system calculates the crane’s centre of gravity and warns the operator before the machine leaves the safe operating zone, an important advantage when working on sloped ground.

Planning software has played a major role as well. Traylor Bros. used Liebherr Crane Planner 2.0 to simulate crane deployments and lifting scenarios before work took place on site. In practical terms, that allowed the project team to assess crane positions, lift paths and possible constraints in advance, reducing uncertainty in a location where adjustments can be costly and time-consuming.

Beyond the lifting work itself, the project shows how modern crane technology is becoming increasingly tied to infrastructure delivery in difficult environments. Capacity remains essential, but so do digital lift planning, machine stability systems, transportability and service support.

As the Juneau Creek Bridge continues to take shape above the canyon, the project underlines a familiar reality for contractors working in remote regions: success depends not only on engineering the structure, but also on engineering the lift plan around terrain, access, safety and schedule.
