| VA1 Groß-Enzersdorf–Süßenbrunn ASFINAG reports preliminary site work in 2026 and states that route construction is planned to start in 2027. The project page gives completion in 2032. The stated length and cost cover VA1. | Planned | 11 km |

| VA2 Schwechat–Groß-Enzersdorf and Donau-Lobau tunnel ASFINAG lists VA2 as planned, with construction no earlier than 2030 and an approximately ten-year duration. The project was halted by the transport minister in December 2021; its present planned status follows ASFINAG's current page. The 8.3 km figure is the tunnel length, not the full VA2 route length, so no total route length is recorded. | Planned | 8 km | – | – | – | – | – |
