In bridge work zones, frequent and abrupt changes in geometry are recommended.

• A. True
• B. False
• C. Not sure
• D. Depends on context

Answer: (B)

In bridge work zones, traffic should pass through with predictable, gradually changing geometry. Frequent abrupt changes in lane width, alignment, or channelization force drivers to brake or steer suddenly, which increases the risk to both motorists and workers and undermines the effectiveness of the traffic control plan. The safety approach is to design for smooth transitions, with adequate taper lengths, clear lane guidance, and proper speed reductions so drivers can anticipate what’s ahead well in advance. Because of this, the statement is not correct—rapid, abrupt geometry changes are not recommended. If a change is necessary, it should be implemented with clear signage and gradual transitions, not abrupt shifts.
