I-35W St. Anthony Falls Bridge Design-Build

TKDA played a major role in the design of the I-35W St. Anthony Falls Bridge Project. As part of the FMJV Design-Build Project Team, TKDA was the Design Engineer of Record for the:

• Interstate highway and local roadways
• Second Street bridges
• Retaining walls
• Water resource features
• Pedestrian tunnel
• Signing, signals, utilities, and lighting
• Maintenance of traffic

TKDA’s design for the Second Street Bridges accommodated the future profile lowering of I-35W north of Second Street and thereby avoided the need to prematurely replace the bridges. Our innovative use of loop anchors accommodated the stringent project-specific design criteria, the necessary shallow structure depth to accommodate future infrastructure improvements, and the bridges’ high post-tensioning requirements. The project, which received national attention, was completed and opened to traffic months ahead of the original aggressive schedule.
