grid deduction - Puzzles: Meander



I have come up with an interesting type of puzzle based on the mathematical concept of a meander. The concept, of course, is not original to me, but the type of puzzle is, as far as I know.


A meander is a curve that intersects a given line a certain number of times, but does not intersect itself. To complete each puzzle, you must draw a meander, starting at one red node and ending at another, that passes through all nodes on the given line. Additionally, each number above or below the line and between two of its nodes denotes the number of "arches" of the meander that must cover it, or segments of the meander on one side of the line that join two nodes on opposite sides of the number. Here is an example puzzle:
