🔍 Key Concepts

• Mississippi River mile markers (river miles) and how they are measured along the navigation charts • The location of the Yazoo Diversion Canal relative to major Mississippi River reference points • How to use an Inland River Chart/Bridge List or index to find distances between specific features (canal mouths, bridges, cities)

💭 Think About

• On a river chart, where would you look to find the river mile for the mouth of the Yazoo Diversion Canal? • On that same or nearby chart, where would you find the river mile for the railroad and highway bridge at Baton Rouge, LA? • Once you have both mile markers, what simple arithmetic operation do you perform to get the distance between them?

✅ Before You Answer

• Make sure you are using river miles along the Mississippi River, not highway miles or general map distances • Confirm the river mile at the Yazoo Diversion Canal and the river mile at Baton Rouge RR/Hwy bridge from the appropriate chart or reference list • Double-check your subtraction and see which answer choice is closest to your calculated difference
