Intergalactic gate bridge
A collection of Stargates chained in relative proximity in order to span the 3-million-light-year void between the Milky Way Galaxy and Pegasus Galaxy, allowing time and power-efficient transport between Stargate Command and Atlantis. Seventy Stargates encompass the entire chain.
Developed by Rodney McKay and Samantha Carter, the bridge saves three weeks of hyperspace travel time. Thirty-four Stargates, each from the Pegasus and Milky Way gate systems are strategically placed in the void between the galaxies, meeting at the Midway Space Station.
A traveler may enter via Stargate Command or Atlantis and a macro written by Dr. McKay commands each individual gate in the chain to forward the energy pattern along the chain until reaching Midway.
Once at this station, a traveler need only cross the room and enter the opposite Stargate network, where a similar macro process commences, until he or she is deposited at the opposite end of the chain.
Total travel time through the bridge is estimated at 30 minutes.
