i-35 replacement bridge
MacDonald Architects collaborated on this design/build project with CH2MHill, Jacobs Engineering, and CSM Contractors.
In order to create a design that works in harmony with the neighboring historic bridges of the Twin Cities, MacDonald Architects took design cues from the nearby 10th Avenue Bridge. At the same time, the design sought to minimize the visual mass of the bridge by utilizing a slender main span and gentle arcs. Ultimately, the design was both modern and complementary to the aesthetic features of the region.
Although MacDonald Architects, along with the team, secured the lowest bid on this project, coming in at $60 million below the cost of the winning design, our team was not successful in winning this design/build contract. Our design was a steel bridge, but ultimately, the owner decided to go with a concrete bridge design, and we feel that this difference was the reason why we were not successful.
