Three Flags Highway Runs from I-15 near Phelan to New Pine Creek, CA and to Laurier, ID at the US/Canada Border
US 395 is called the “Three Flags Highway” because it connected Mexico, the United States, and Canada. The former southern end, however, did not quite go through to Mexico. It ended in Downtown San Diego. US 101 took up the rest of the distance to San Ysidro at the border. This route serves traffic bound for the Eastern Sierra region of California and the Carson City/Reno area of Nevada. Plans call for an eventual upgrade to expressway south of State 58 (Kramer Junction) but won’t happen for many years. Prior to 1972, US 395 continued down to San Diego via I-15, I-215, and SR-163.
