The three bridges that this book-let covers are on two rivers. Both rivers are tributaries of the Grand.
Thornapple River Bridges
One bridge is on the Thornapple, a tributary that joins the Grand in Ada, where the bridge is located.
Flat River Bridges
The other two bridges are on the Flat, a tributary that joins the Grand in Lowell. Both bridges are north of Lowell.
