What term is the distance between the end of wing walls at abutments or the deck lane length for bridges without abutments?

• A. Deck Width
• B. Clear Span
• C. Total Bridge Length
• D. Clearance of bridge span

Answer: (C)

The term being tested is the overall, end-to-end length of the bridge. This distance includes the entire span from one end to the other, accounting for any wing walls extending beyond the abutments and, in bridges without abutments, the full deck length between the project’s ends. In other words, it’s the total bridge length you’d measure from the far end of one deck to the far end of the other, not just the portion between supports.

Drafted concepts for the other terms: deck width is simply how wide the deck is, not related to how long the bridge runs. Clear span is the distance between the inner faces of supports (the span between abutments or piers), excluding any overhangs. Clearance of the bridge span refers to vertical clearance under the bridge, not the horizontal length.
