The project consisted of two three-lane bridge approached. The 193 individual slabs were installed between slipformed sections of new highway and two existing bridges. Normal weight precast concrete Super-Slab® panels were used for full-depth replacement on the roadway. Work was completed during four separate weekends while traffic was detoured to the other side of the divided highway. High production dual slope Supergrading was done using a laser guided Somero S-240.
