Superior Street Reconstruction
An iconic street reimagined
The mile-long Superior Street Reconstruction Project was a complete rebuild of one of Duluth’s oldest and most iconic streets, from Mesaba Avenue to Fourth Avenue East. Nearly every major utility within the corridor was replaced and several new major utility systems were added. With a total project length of over one mile, the project overlapped key connections between the downtown area, the Canal Park tourism and business district, and the Interstate 35 corridor at Lake Avenue and Fifth Avenue West.
LHB was hired to manage and design the project through all phases of project development and delivery beginning with a comprehensive topographic and boundary survey of the downtown corridor; preliminary design, public engagement, and project scoping; final design; and construction. LHB’s work included roadway design; utility design for new water main, gas mains, and sanitary services; drainage design for stormwater management, treatment, and conveyance; structural engineering design for foundations, retaining walls, building vault restoration, and bridge modifications; mechanical and pipeline engineering design for new steam systems; electrical engineering design for high voltage power distribution; architectural design for transit and building modifications; and land surveying services for topographic survey, utility locates, and construction staking. LHB also provided support landscape architecture services, including the creation of schematic design sketches and renderings, public engagement facilitation, public plaza design, and quality assurance for the overall streetscape design.
"LHB exceeded our expectations with their innovation. The trust and past relationships LHB had with the City, other agencies, the contractor, and the public, helped ensure a design that met all the diverse needs of the project and which we believe could not have been replicated by another firm."
Duncan Schwensohn, PE, Senior Engineer City of Duluth
"LHB showcased their professionalism and expertise through every phase of the Superior Street project. Not only did they design the project, they showed how much they cared about the outcome. We are fortunate to have such a talented firm headquartered in the heart of downtown Duluth."
Kristi Stokes, President Greater Downtown Council
