L'Alpe d'Flag

Anyone notice the painted 21 turns on Flagstaff recently? Did you see the name "Hampsten" painted on the road on the bridge starting out the climb? Wonder what this is all about? It's all cryptic until you reach the very top of Flagstaff where everything makes as the words "L'Alpe D'Flag" are painted on the road which appears to try to represent the 21 turns of L'Alpe d'Huez.

If anyone has photos of these numbers or the finish please send them over! Anyone know of a MapMyRide or NetCairns map representing this?

Apparently each of the 21 turns on the real L'alpe d'Huez has a sign on it like the one below with tour stage winner names.

Here is what is on the road
