There is a construction on the east side of Route de Ferney at the bus stop Gd. Saconnex Place. Some stops are temporarily in Route de Colovrex (on the other side of the parking), some a bit more north in front of Denner. Pedestrian crossing options of Route de Ferney are limited. The east sidewalk at Route de Ferney between "Place de Carantec" and "Route de Colovrex" is blocked by the construction and cannot be used.

There are Footways missing.
The following route seems way too long:

ce carrefour et dessiné de manière étrange. Sur place, c'est une route principale de laquelle partent deux route secondaires. tout simplement. il n'y a pas toutes ces voies dans tous les sens
