From the parking areas, riders use elevated walkways that bridge the east and westbound lanes of I-66 to reach the platform and mezzanine.

The station provides easy access to the nearby Town of Vienna, the City of Fairfax, and the main campus of George Mason University.

[6] In March 1999, the station name was changed to Vienna/Fairfax–GMU,[7] which was misleading because a drive or ride on an infrequent CUE Bus or Metrobus is required to reach Fairfax City and GMU.

[12] On June 22, 2024, many Fairfax Connector bus routes to points west (Centreville, Chantilly, Fair Oaks, and Penderbrook) stopped serving the station as part of the agency's CCVT (Centreville-Chantilly-Vienna-Tysons) Phase 1 service changes.

[13] In line with high-density development, the Fairlee Metro-West project aims to increase the housing density around the Vienna station from 60 single-family homes to 2,250 condominiums and townhouses.

Tail tracks extend a considerable length to the west of the station, used both as train storage and as a provision for a future western extension.
