The Pillette Bridge NERO Checkpoint is a Highway 97 checkpoint overrun by Freakers, west of the Bare Bay Ambush Camp. It pays Diamond Lake and holds an injector.
Freakers have taken over the site, so thin them out with Molotovs or a shotgun before you touch the generator. Cut or shoot the loudspeakers before you turn the power on, or they blare and draw Freakers. Then get the generator running with fuel, a new fuse or a reconnected cable, depending on the site.
With the power on, the NERO trailer opens. Inside are the NERO Injector, which raises Health, Stamina or Focus, and the Intel Recorder. A powered checkpoint becomes a fast travel point.
Bare Bay Ambush Camp is just east and also pays Diamond Lake.
