What is vertical lift Bridge?
- 63-metre stretch in this bridge will lift up while remaining parallel to the deck to allow access to the ships.
- Current bridge has the ‘Scherzer’ rolling lift technology in which the bridge opens up horizontally, to let ships pass through.
- Vertical lift technology in new bridge will lift part of bridge vertically upward.
- In comparison to existing manual operation and control, the new bridge will have electro-mechanical controlled systems which will be interlocked with train control systems.
Vertical lift bridges use a system of counterweights and cables to move an interior lift span section that remains horizontal as it is raised up and down like an elevator, allowing river traffic to pass beneath the structure. The Hawthorne Bridge is the most prominent example of a vertical lift bridge.
