Project is limited to the repair of Bridge # 28C-0143 that will consist of damage to bridge abutments caused by scour within the streambed area on the southwest an northeast banks. The southwest bank will consist of the placement of pressure treated timber that will be placed over the H piles and have pressure treated grout filled into the voids behind the boards. A 40 linear foot trench, 3 feet deep will be dug in front of the abutment and lined with filter fabric and rock slope protection. the northeast side will consist of trenching 23 linear feet, 4 feet wide, 3 feet deep and lining with filter fabric and rock slope protection.
