The new steel beams shall be lowered in place from above to eliminate or minimize work from the bottom of the ravine channel. Alternate Bid: The alternate bid includes work described above. Three structures are included in the alternate bid: Beech Street, St. Johns Avenue, and Judson Avenue bridges.
