Diamond Lake Road Bridge — Minneapolis, MN


Bridges are a critical component of a healthy infrastructure. Our engineers have designed award-winning structures that range from small piers and boardwalks to major river crossings and railroad bridges. Balancing functionality, efficiency, safety, and aesthetics, our bridge team has designed more than 250 bridges, including spans for 75% of Minnesota’s counties. We are qualified as Bridge Consultants by the Minnesota Department of Transportation, and we are prequalified Consulting Engineers by the North Dakota Department of Transportation. For existing structures, our team provides recommendations for condition code revisions, structural rating revisions, load postings, and bridge replacement versus rehabilitation. We’re here to help you ensure safe passage for your constituents.


Vehicular Bridge

Widseth Smith Nolting has designed hundreds of vehicular bridges across the five-state region. Our award-winning designs ensure safe, efficient travel that can stand up to harsh weather conditions and heavy traffic volumes. In addition to bridge design, we also provide hydraulic analysis, scour analysis, bridge inspections, permit applications, load capacity ratings, and construction observation and administration.
