How far is Carlsbad California from Seattle Washington?

Answer 1

1,235 miles taking I-5 SOUTH, via I-205 SOUTH to bypass PORTLAND (EXIT 7 off I-5 in WASHINGTON), and via I-405 SOUTHto bypass LOS ANGELES (EXIT 158 off I-5 in California).

NOTE: at the south end of the I-405 L.A. bypass, you can connect to I-5 SOUTH towards San Diego two ways: you can either go to I-5 SAN DIEGO directly from I-405, or you can connect to I-5 SAN DIEGO indirectly via the TOLL ROAD (SR-73 SOUTH at EXIT 10 off I-405), which provides a shorter, quicker, easier, and an all-around smoother connection to I-5 SAN DIEGO.
