A method of converting a conventional grid deck to an exodermic deck is disclosed. The method includes the steps of removing existing concrete if the deck is a filled grid. Tertiary load bearing bars are placed on top of the grating parallel to and between the primary load bearing bars. Shear members are vertically mounted on the tertiary load bearing bars to provide structural integrity. The interstices of the grating are filled to prevent concrete from penetrating the grating. A concrete overlay is poured and cured on the top surface of the grating and the interstice filling is removed.
