Given that:

Width of Deck slab=10.2m

Span of the bridge=12m

Pier size=2.5m Diameter

Seismic Zone=IV

Wind speed =47 km/hr

The site is away from Bay of Bengal=60km radius

Unit Weight of Soil=19 KN/m3

Dead Load of Super Structure:

Deck slab =10.2 X 0.225 X25 =57.375 KN/m

Box girder:

Bottom portion =4.02 X 0.225 X25 = 20.1KN/m

Side walls =2.127 X 0.25 X 25 X2 =26.5875KN/m

Total load (Excluding Slab) = 46.6875 KN/m
