Featured Presentation: ABC and Innovative Bridge Construction for Minnesota Local Roads (35 minutes)

Description:  In cooperation with the Minnesota Department of Transportation, the Minnesota County Engineers Association, the Minnesota Local Road Research Board, and the FHWA Minnesota Division Office, a number of counties in the state have built accelerated and innovative bridge construction projects on their local roads in the past few years.

These projects have included side-by-side precast box beams on sheet pile abutments, mechanically-stabilized earth (MSE) walls with single-line pile abutments, precast inverted tee slab span bridges, large precast box culverts, and three-sided structures. The first two county precast inverted tee beam bridges have been recently constructed based on the groundbreaking work of the Minnesota DOT for this bridge type, and the first Minnesota county bridge with geosynthetic-reinforced soil (GRS) abutments is scheduled to be built this construction season.

Through many domestic local bridge scanning tours with federal, state, and local partners, the featured presentation describes the reasons that Minnesota counties have implemented ABC and innovative bridge construction techniques. The bridge elements, details, and costs related to these local bridge projects will also be highlighted.
