Mary Pat Christie will place the final board on the Seaside Heights boardwalk that was destroyed by Superstorm Sandy.
The initial project cost $3.6 million to replace the boards. Railings, lighting and ramps cost extra.
Seaside's boardwalk was featured in MTV's "Jersey Shore" reality series and is home to a variety of arcades, amusement rides and food concessions.
Friday's ceremony will take place between Franklin and Lincoln avenues.
