The San Hieronymo rail bridge under blockade in 1970.

The rail bridge on the San Hieronymo Peninsula was a structure built for the purpose of providing passage between the eastern half of the peninsula and the western half, which were divided by a river. Buildings included a cabin on the western side of the bridge, and a security station and observation post on the eastern side.


San Hieronymo Incident

Main article: San Hieronymo Incident

In 1970, the rail bridge was closed off and turned into a checkpoint by Red Army soldiers under the command of renegade FOX commander Gene, presumably due to the actions of Big Boss's resistance group. After learning that the bridge was under heavy guard and that trucks were being used as road blocks, Big Boss and Roy Campbell realized that they would be unable to sneak through, and lacked sufficient manpower to break through. They then decided to create several diversions by destroying key enemy facilities and prominent landmarks via TNT, to draw forces away from the bridge. After succeeding in this, Big Boss's resistance are able to cross the bridge, though they now had to avoid the newly deployed FOX soldiers that were operating in the area.

Later, a map showing the location of the guest house was supplied to the rail bridge security guards. This map was stolen by the resistance group in order to rescue Big Boss, who had been caught and imprisoned in the guest house.
