Question: Boulder City, Nevada, with a population of 15,023, is host to which 202 mi 500-kilovolt power line? 
Context: Path 61 or the Lugo - Victorville 500 kV Line is a relatively short AC 500 kV power line that runs from Southern California Edison's (SCE) Lugo substation southwest of Hesperia to Los Angeles Department of Water and Power's (LADW&P) Victorville substation north of Victorville, California.  The line is an important connection between two out of the four parts that make up the massive Path 46 transmission system in southeast California since the line allows power flow to be rerouted on Path 46 when necessary.  Half of the length of the 500 kV power line is owned by SCE to the south and LADW&P to the north.  The entire line is located in the Mojave Desert and the High Desert regions of California. One Nevada (ON Line) is a 235 mi , 500-kilovolt, 600 MW power line that runs from Southern to Northern Nevada.  25% of the transmission line is owned by NV Energy which operates and offers the line's capacity under the terms of NV Energy's Open Access Transmission Tariff.  Great Basin Transmission South owns 75% of the line.  The line runs from the new Robinson Summit Substation in Ely, Nevada to Apex, Nevada connecting with the existing NV Energy Harry Allen Substation, and uses tubular guyed-V towers on a single point foundation. Boulder City News was a weekly newspaper distributed in Boulder City, Nevada.  The paper was first published in 1937.  When it ceased publication, the paper was published by the Greenspun Media Group.  The paper was focused on the community of Boulder City including the local sports, news and events.  According to the Circulation Verification Council, for the first half of 2009 the paper's circulation increased by 29.3% which was the largest increase in the country for any community newspaper. The Kalamata–Pyrgos–Patras Line is a power line running near Pyrgos, west of Amaliada, east of Gastouni, 1.5 km west of Lechaina and encircles to the north, the southern part of the plain and connecting with another line connecting from Megalopoli.  This power line has several power stations including Pyrgos, Amaliada, Lechaina, Varda and Lappa.  The power line has several branches including a 5 km long line to near Lappa.  The line linking Kavasila and Zante passes near Kavasila, about 1 km south of Dimitra, south of Kastro, north of Loutra Kyllinis and into the island of Zante.  Most of the line is underwater. Sunrise Powerlink is a high-voltage power transmission line by San Diego Gas & Electric (SDG&E) in San Diego County, California and Imperial County, California.  The project was approved by the United States Forest Service (USFS) in July 2010, the U.S. Bureau of Land Management (BLM) in January 2009 and the California Public Utilities Commission (CPUC) in December 2008.  SDG&E states that the 117 mi long 230/500 kilovolt power line will bring 1000 megawatts of renewable energy from the Imperial Valley to San Diego County.  The cost of the project is estimated to be $1.9 billion for construction.  SDG&E, which will receive a guaranteed profit of over $1.4 billion from the construction of the line, claims that the power line is necessary to support future growth of the San Diego region, and its economic benefits to the region will measure on the order of $100 million per year.  However, the project has been called one of the most controversial projects ever proposed. Path 62 or the Eldorado - McCullough 500 kV Line is a short 0.6 mi 500 kV power line linking Los Angeles Department of Water and Power's (LADWP's) McCullough substation to Southern California Edison's (SCE's) Eldorado substation in the Eldorado - Marketplace - McCullough substation complex.  Like Path 61, this short, yet important 500 kV allows for power flow to be rerouted on different 500 kV lines that make up the massive Path 46 transmission system when necessary.  Power generated from Hoover Dam, and fossil fuel power plants in the Four Corners region is routed to this substation complex via many other 500 kV lines that connect to this substation complex. The Körsch Viaduct is a bridge that crosses the Körsch Valley (river Körsch) in Germany, supporting a road around Nellingen.  It was built from 1991 to 1993 by incremental launch.  It was handed over to the public in 6.9.1995.  The bridge also crosses a 110 kilovolt power line of the EnBW AG and a sewage treatment. Boulder City is a city in Clark County, Nevada.  It is approximately 26 mi southeast of Las Vegas.  As of the 2010 census, the population of Boulder City was 15,023. The Pylons of Messina are two free-standing steel towers, the Sicilian one in Torre Faro and the Calabrian one in Villa San Giovanni.  They were used from 1955 to 1994 to carry a 220 kilovolt (150 kilovolt until 1971) power line across the Strait of Messina, between the Scilla substation in Calabria on the Italian mainland at and the Messina-Santo substation in Sicily at . Path 64 or the Marketplace - Adelanto line is a 202 mi 500-kilovolt power line that runs from the Adelanto substation near Adelanto, California and the High Desert to the Marketplace substation near Boulder City, Nevada.  Path 64 is one part of the Path 46 transmission system in southeastern California.  This power line is operated by Los Angeles Department of Water and Power (LADWP).  This line, along with Path 27 and the other Path 46 lines, bring over 10,000 megawatts of electrical power to the Los Angeles area.  Path 64 is an essential line for powering Los Angeles.
Answer: Path 64
