Agnew is not a through road. The county road ends after GC2DDDF prior to the canal, trickling down to a single track driveway to a farm. Even the Google Earth street view vehicle stopped at the end of the pavement . The canal road (also shown at Country Lane) which parallels I-82 is not open to regular travel. You'd need to turn around, go south to Knight Road, go east, then turn north on Powerline Road.
