Harney Lane Bridge No. 29C-341 Scour Mitigation Across Paddy Creek Project

Harney Lane Bridge No. 29C-341 Scour Mitigation Across Paddy Creek Project

The existing Harney Lane Bridge is an approximately 86 foot long, three-span, reinforced concrete slab structure. Due to channel degradation over time, bridge piers and the top of the west abutment footing have become exposed. To provide scour protection, the San Joaquin County Department of Public Works is proposing to install open cell articulated concrete block (ACB) around the piers and abutments. The ACB would be placed on geotechnical fabric, and the open cells would be filled with aggregate. While the maximum depth of excavation is anticipated to be 3 ft, the exact depth would be determined during design of the improvements. The majority of work is planned to be confined to Harney Lane right-of-way (ROW); however, forming of the cut-off wall would require construction crews to work outside the Harney Lane ROW. All aggregate material to be used for scour protection would be sourced from a permitted quarry. No work is proposed on the bridge structure itself.
