Please reference the bridge plan sheets 1, & 4 which show the limits of partial demolition of the existing box culvert structure.

The existing footing shown on bridge plan sheet 4 is connected with slab span foundation. Therefore, it cannot be removed in its entirety. However, it is acceptable to partially remove the existing footing no more than 2' away from the slab span foundation. Concrete removal shall be in accordance with the Road and Bridge Specification 412.03 without damage to the existing abutment footing.

The minimum terminal wall length per bridge plan sheet 5 is 7'0". With 7'0" each side totaling 14'0" of cast in place terminal wall that would leave only 6'0" for RAILING, CPSR 3 RAIL in between. Is this the intent of proposal line number 0910 RAILING, CPSR 3 RAIL to have 7'0" long terminal walls each side and 6'0" of 3 rail in between or to just make the total length of terminal wall 20'0"?  
Answer   1 previous answer(s) Date: 8/19/2022 2:18:27 PM
There is no CPSR 3 RAIL in between the terminal wall. The purpose of Line number 0910 RAILING, CPSR 3 RAIL is to pay for Railing 42" CPSR Terminal Wall. See sheet 2 – PART TRANSVERSE SECTION, the total length of the left side railing is the entire terminal wall (20 LF.)
