🔍 Key Concepts

• Think about typical dimensions of mainline locks on major U.S. inland waterways (lengths often close to a standard barge tow length). • Recall that Old River Lock is part of the Mississippi River / Atchafalaya River control system, not a small auxiliary lock. • Compare the widths commonly used for modern commercial locks (e.g., what accommodates standard barge widths side‑by‑side).

💭 Think About

• Which option best matches the size needed to pass a full inland barge tow without breaking it into many pieces? • Look at the widths listed: which are wide enough for typical barge configurations, and which seem too narrow for a main commercial lock? • Among the lengths given, which are closest to the standard 1,200‑ft class lock used on many major rivers, and which are clearly shorter?

✅ Before You Answer

• Verify what a standard barge size is (approximate width of one barge and of common tow arrangements). • Check which choices have a length approaching 1,200 ft, a common standard for large river locks. • Confirm that the width you choose makes sense for at least one or more barges abreast in a tow, not just a single small vessel.
