Providence Park Stadium Expansion
Home to two professional soccer teams, Providence Park Stadium is one of the most prominent outdoor sports venues in the United States. As one of the country’s oldest soccer stadiums, the arena has undergone numerous renovations, but none as transformative as its most recent expansion.
Located in Portland, Oregon’s historic Goose Hollow neighborhood, Providence Park Stadium is home to Major League Soccer’s Portland Timbers and the National Women’s Soccer League’s Portland Thorns FC. Originally constructed in 1926, the stadium has undergone several additions and renovations to accommodate Portland’s thriving sports culture and showcase the city during signature national and international sporting events.
The recent expansion increased the stadium’s seating capacity from 21,144 to 25,218, allowing Providence Park to take its place among the larger soccer stadiums in the United States. The vertical expansion was inspired by soccer stadiums and open-air arenas around the world, including La Bombonera in Buenos Aires, Argentina, and London’s original Globe Theatre. The four-level expansion includes a 150-foot (46-meter) cantilevered roof canopy with an architecturally exposed structural steel (AESS) lattice that extends from the roof to the sidewalk below, creating the architectural hallmark of the expansion.

CAST CONNEX standardized Universal Pin Connectors (UPC) were selected for the expressive base connections of the AESS lattice structure. In total, 122 UPCs were used to complete this aspect of the project, creating a clean, open, and unobtrusive views for the club levels, the arcade, and concourse at street level.
The unique placement of the pre-engineered cast steel components allowed the design team to create a distinctive architectural form that transforms the century-old structure into a modern landmark. CAST CONNEX steel casting solutions provided the project team with a repeatable and elegant connection solution for a celebrated sports and entertainment venue in the heart of downtown Portland.
