The intersection associated with the name Echo is which pair?

• A. I-10 & 89
• B. 90 & 89
• C. 89 & 87 & power lines
• D. 87 & I-10

Answer: (A)

Intersections named with phonetic letters like Echo are fixed navigation fixes used on charts. Each named fix marks a specific point where navigation lines cross, often at a highway or route intersection. Echo corresponds to the point where Interstate 10 crosses U.S. Route 89. That’s why the correct pairing is I-10 and 89. The other options describe different features or highway combinations that do not define the Echo fix.
