Gates Stations and Bridges
Gates, stations, and bridges are structures that serve different purposes, such as traffic control, transportation, and space travel.

Gates
Movable bridge warning gates: These gates are installed on movable bridges to prevent vehicles and pedestrians from crossing the stop line and entering areas with potential hazards.

Movable bridge resistance gates: These gates are placed downstream of the warning gates to physically deter road users.
Stargates: These gates are used in space travel to connect different galaxies.

Stations

Midway space station: This space station was located between the Milky Way and Pegasus galaxies and served as the midpoint of the McKay/Carter Intergalactic Gate Bridge.

Bridges
