The main connecting road of the municipality is the route du Mandement, which connects the D-884 in France to Meyrin via Dardagny, Russin, and Satigny. The A1 motorway connecting Geneva to the rest of Switzerland and to France passes underneath Vernier, close to border with Satigny. At the moment, there are no direct exits to Satigny, the closest exits being located in Vernier/Meyrin and Bernex. However, an existing project in advanced planning stages, the "barreau routier de Montfleury", whose construction was originally planned to start in 2020, will create a direct connection to the A1 in direction to Bernex and France from La Tuillière and ZIMEYSA industrial areas. This project aims to remove from local roads much of the road traffic to and from the three industrial areas of the town. Discussions are underway to modify the original plan to include a connection in direction to Switzerland as well.
