Bridge Replacement & Rehabilitation

Bridge Replacement/Rehabilitation These projects include the replacement of an existing bridge structure, commonly because a structure has reached the end of its service life, to increase the vertical clearance under the structure or possibly due to physical damage to the structural members. Generally, this type of work involves substantial approach work, particularly if a temporary bridge may be needed to maintain traffic while the construction is taking place. Rehabilitation work is generally applied to existing bridge structures to help preserve the structure and extend its service life. This work can include but is not limited to bridge painting, deck repair, bearing replacement or bridge rail upgrades.
