1. Deck through bridge
2. Half through or suspension bridge

Categorization based on the method of connection of various parts of superstructures -

1. Pinned connection bridge
2. Riveted connection bridge
3. Welded connection bridge

2. Minor bridge(less than 6 m-60m)
3. Major bridge(more than 60 m)
4. Long span bridge(more than 120 m)
