What is the horizontal clearance of the Duwamish Rail Bridge?

• A. 40'
• B. 50'
• C. 60'
• D. 70'

Answer: (B)

The horizontal clearance of the Duwamish Rail Bridge is 50 feet. This vertical clearance specification is essential for ensuring that the bridge can accommodate the safe passage of trains and other rail traffic beneath it, as well as allowing for appropriate clearance for any potential vessel traffic in the waterway below. A clearance of 50 feet strikes a balance between meeting regulatory requirements and operational safety for different modes of transport. In the context of bridge design and operation, this measurement is crucial in preventing collisions and ensuring safe navigation near the bridge. Compliance with guidelines and regulations regarding horizontal clearance ensures that all public and private stakeholders understand the limitations and safety parameters associated with the structure.
