This is the only road to and from the REPCONN test site, and many feral ghouls are present. Many items can be found including chems on top of the bridge, within the checkpoint itself, and behind the sandbag barricades. There are also several ash piles containing rebar clubs.
Atop the bridge, there is a pyramid created from empty Nuka-Cola bottles, wherein touching it or any item on the table will cause the pyramid to collapse.
REPCONN test site checkpoint appears only in Fallout: New Vegas.
