Consider a 3x3 grid where you start at the top-left corner, labeled $A$, and need to get to the bottom-right corner, labeled $B$. You can only move to the right or down along the drawn segments. One segment (from the middle cell of the top row to the middle cell of the second row) is blocked, and you cannot move through it. How many different routes are there from $A$ to $B$?

** Diagram not shown, but to visualize:
- A 3x3 grid with cells (columns x rows) as squares.
- Start: Top-left (A). 
- Finish: Bottom-right (B).
- Blocked segment from (1,2) to (2,2).**
