) is also located. As the line leaves Adelanto substation, the 500 kV line follows
Highway 395 for a distance northwest. At Kramer Junction (intersection with State Route 58), the line turns east. The power line then meets the other Path 46 power lines from Victorville along with the Intermountain DC line near
Newberry Springs and runs parallels with them for a short distance; all of the lines at this point are now heading northeast. After a few miles, the line crosses over the other Path 46 and Intermountain DC lines and splits off of the corridor; heading towards the
Interstate 15 where it runs alongside the highway through the desert until both descend into the
Ivanpah Valley. Just prior to the California-Nevada border, the Path 64 line crosses the Interstate 15 once more before turning north and entering Nevada southeast of
Primm where it rejoins with the Path 46 and Intermountain lines again north of the community. The now scattered power lines then head in a roughly northeast direction across the desert to the
Eldorado - Marketplace - McCullough substation complex. Path 64 ends at the Marketplace substation, where
Path 63, another long-distance transmission line from
Arizona also terminates.
Power transmission capacity
The lone 500 kV power line can transmit 1,200 MW of
electrical power.
