Lincoln Avenue Bridge Widening

The project consisted of widening Lincoln Avenue Bridge over the Santa Ana River on both sides with an 18 feet reinforced concrete box girder superstructure, pier walls, debris noses, diaphragm type abutments, and wing walls, all founded on steel driven piles. This project also removed unsound concrete on existing bridge deck, fill deck voids with rapid set concrete, treat bridge deck with methacrylate, and overlay/slurry seal the road approaches. There were many challenges due to the close proximity of popular hiking/biking trails, groundwater basins, and a gravel/asphalt plant. The project added two travel lanes, bike lanes, and sidewalks while upgrading the barrier. The public now feels safer crossing the bridge connecting the Cities of Orange and Anaheim. Also, the much needed maintenance will continue the life of the bridge for many years to come.
