Puzzle of the Week #9 - Third Avenue

Draw a path that visits every dot once only.

The path can be made only of horizontal and vertical lines.

The path cannot cross itself or branch off, and must return to the start to form a complete circuit.

Every third turning point of the path has been marked with a triangle symbol. In other words, at each symbol there will be a 90 degree turn in the path, and there will be two further 90 degree turns before the next symbol.
