~ Project would have been a good candidate for the sub-regional tier design guidelines.
 ~ At least one of the three spans on this bridge might have been eliminated.
 ~ Drilled shafts appear overdesigned, possibly due to the minimum column size suggested in the Structure Design Manual.
 A/I ~ Structure Design will investigate reducing the minimum diameters for columns and drilled shafts.
~ 3-span (25'-60'-25') 36" prestressed concrete girder bridge.
 ~ Location features rock near the natural ground elevation.
 ~ Foundation consists of drilled shafts with bent caps at the natural ground elevation.
 ~ A single span bridge should have been considered.
