The Arlington River Bridge on University Boulevard in Jacksonville, Florida replaces an aging bridge with a new two-lane concrete bridge that has 6½ foot-wide sidewalks, 4 foot-wide bicycle lanes, decorative lighting, and architectural railings. Florida Department of Transportation (FDOT) project planning required: uninterrupted vehicular traffic, pedestrian, access to the mainland, and continued marine traffic during construction. Therefore, the project entailed construction of a temporary bridge, demolition of the existing bridge, construction of the new permanent bridge, and finally removal of the temporary bridge.
To enhance sustainability and durability in this salt water environment exposed to constant tidal action, 60% slag cement was used a ternary concrete mixture with 30% portland cement, and 10% fly ash. Used in the bridge deck as well as the architectural railing, this concrete mixture design exceeded Florida Department of Transportation specified surface resistivity criteria and strength requirements. Durability and strength objectives were achieved at a reduced environmental footprint, since slag cement is a recycled material. Slag cement provided consistent concrete performance and a lighter color concrete.
