How Do You Build a Bridge Across a Cliff?

3-Second Blueprint (English)

1. Driven steel piles transfer heavy bridge pier loads past soft riverbeds down into stable load-bearing strata beneath the water.
2. Interlocking steel cofferdams sealed with underwater concrete allow engineers to pump enclosures dry and cast reinforced footings.
3. Heavy rock riprap prevents river-current foundation scour while deck bearings and expansion joints absorb thermal movement.
