I am working on a senior design project of designing an overpass over I-95 for Viera West. My part is to design the foundations, and the structural engineer of our group is lazy and hasn't provided me with the design loads yet.
Does anyone know what would be an estimated Design load on the overpass?
It's a 4-lane overpass (2 lanes separate and 2 lanes separate). The span of the overpass is 202'. For live load we are using HS20-44 truck which I think gives a 72kips load.

Any help would be highly appreciated
