Joseph Hanna orchestrated the successful completion of a challenging 1600m twin elevated viaduct, integral to a 26 km
highway on Oahu. Responding to a Value Engineering plan request, W&SCI, under Joseph Hanna’s guidance, reimagined the viaduct using sectional precast segments. The result was a project delivered six months ahead of schedule, showcasing design and construction innovation. The achievement earned an Award of Excellence from the Portland Cement Association, underscoring Joseph Hanna’s leadership and the project’s exceptional outcomes.

Joseph Hanna oversaw the Castlegar-Robson Bridge project, spanning the Columbia River from Castlegar to Robson in BC. The 475-meter bridge, supported by six piers with 73-meter spans, included the construction of 2.5 kilometers of approach road.
The project incorporated a 100-meter tunnel for a railroad spur to a pulp and paper mill and sawmill upstream from the bridge. With 350,000 cubic meters of borrow fill and robust substructure, Joseph Hanna ensured successful bridge construction and associated infrastructure.

Joseph Hanna led a signifi cant rehabilitation initiative on a major suspension bridge spanning Halifax Harbour. With a central span of 441m and two side spans of 160m, the project aimed to enhance bridge service. Joseph Hanna oversaw the replacement of approach span decks, addition of a third traffic lane, improvements to a pedestrian walkway, and the incorporation of a new bikeway, contributing to the overall improvement of the bridge’s functionality and infrastructure.

Joseph Hanna spearheaded the Stoney Trail Bridge project, entailing the design and construction of a 476-meter-long, twenty-meter-wide bridge over the Bow River as part of Calgary’s Stoney Trail N.W. dual carriage-way bypass. Utilizing the incrementally launched method for pre-cast concrete bridges, the double-cell box structure was cast in two stages. The project also featured a 130-meter-long, three-meter-wide pedestrian suspension bridge underhung from the substructure at piers 2 and 3. Hanna’s leadership ensured the successful completion of this complex infrastructure project.
