Deck Width is defined as the sum of which elements?

• A. Deck Width
• B. Clearance above bridge floor
• C. Total Bridge Length
• D. Clear Span

Answer: (A)

Deck width is a transverse measurement—the total width of the deck surface across the bridge. It is determined by adding up all elements that lie across the deck, such as lanes, shoulders, sidewalks, and barriers. This is different from vertical clearance (which is how high you can pass under the deck) or longitudinal measures like the total bridge length or the clear span (which are along the length of the bridge). So the deck width is essentially the sum of the parts that occupy the deck’s width, making the term deck width the correct description.
