The minimum deck thickness varies depending on the girder type and the centerline to centerline spacing. Therefore, for a reinforced concrete box girder bridge, S = 12.00 ft assumes a minimum thickness t = 9 1/8 in. The minimum concrete cover is determined according to CA Table 5.12.3-1. For the top surface of the bridge deck in a non-corrosive atmosphere the minimum cover is specified as: Deck Top Cover: C top = 2.0 in.
