🔍 Key Concepts

• Check the Inland navigation charts or bridge reference tables for the Vicksburg Highway Bridge on the Mississippi River. • Focus on the definition of the main channel span versus subsidiary or secondary spans. • Remember that published spans are measured horizontally between piers that bound the navigable opening.

💭 Think About

• Which of these distances is most typical for a major highway bridge’s main navigable span over a large river like the Mississippi? • If you located the Vicksburg Highway Bridge in a reference (chart, Light List, or bridge list), which column would show the clear horizontal distance between piers for the main channel? • Do any of the smaller distances look more like spans for secondary openings or near the bank rather than the main navigation span?

✅ Before You Answer

• Verify using a current river chart or bridge list for the Vicksburg area, not memory alone. • Confirm that you are reading the value for the main channel opening, not center‑to‑center pier spacing or vertical clearance. • Double‑check that the unit is in feet and that you are not confusing it with vertical clearance in feet above high water.
