Interstate 5 (I-5) is a United States interstate highway that starts at the border with Mexico in San Ysidro, California and runs 1381 miles (2223 km) north through the states of California, Oregon and Washington to the border with Canada in Blaine, Washington. It serves as an important north-south transportation corridor along the U.S west coast connecting the major cities of San Diego, Los Angeles, Portland, Tacoma and Seattle; the three state capitals of California ( Sacramento ), Oregon ( Salem) and Washington ( Olympia ); and two additional major cities in neighboring countries ( Tijuana & Vancouver) just over the international borders. Understand
Interstate 5 (I-5) replaces the former US Route 99, a north-south route along the west coast. The original U.S. Highway 99 was also known as Pacific Highway which ran 1,600 mi (2,600 km) south from Vancouver, BC through Washington state, Oregon and California and then became Mexico Federal Highway 5 in Calexico/Mexicali. Today I-5 ends at the U.S./Mexican border in San Ysidro where it continues another 1,063 mi (1,711 km) from Tijuana to Cabo San Lucas, through the Baja California peninsula, as Mexico Federal Highway 1/1D, while BC Highway 99 continues another 200 mi (320 km) north from Vancouver, through the Sunshine Coast and Whistler, to Cache Creek. Segments of the old Hwy 99 have been re-numbered as State Route 99 (SR-99) in Washington, Oregon and California. Other segments in Washington state have also have been renumbered as SR-11, SR-529 and SR-530; as SR-273 & SR-66 between Ashland and the California-Oregon state line (Exit #1 of I-5) in Oregon;
