After a guarded gate and a 5-mile (8046 m) road tunnel named "Black Mesa South Access Tunnel," it leads inside the facility, near the Freight Yard. This end of tunnel is named "South Exit."
Later, after Barney opens the portal in the Section A-17 Prototype Labs for Rosenberg, Walter Bennet, and Simmons, sending them to the outside end of the tunnel, Rosenberg and Simmons prepare a Black Mesa SUV, which they will use to leave the compound, while Walter breaks the gate open with a crowbar. When Barney's turn comes, however, he is caught in "some sort of resonance displacement," and is unable to reach the access tunnel right away, being first sent to Xen, then to a small store room where he witnesses an unconscious Gordon Freeman being dragged by two HECU soldiers in an industrial area of Sector E. After he finally reaches the scientists, they leave the compound forever, to an uncertain future.
