No, California State Route 1 is the Pacific Coast Highway. However, some parts of CA 1 overlap with US 101 so parts of US 101 are the Pacific Coast Highway, but it's mostly CA 1.
It is the U.S. Route 101.
Interstate 5 - Golden State Freeway Interstate 10 - San Bernardino Freeway Interstate 15 - Veterans Memorial Highway Interstate 40 - Needles Freeway Interstate 80 - Dwight D. Eisenhower Highway/Lincoln Highway CA 1 - Pacific Coast Highway US 50 - Loneliest Road In America/Lincoln Highway US 101 - Ventura Freeway
I don't know about "best", and it isn't coastal for the entire distance, but US 101 (aka Pacific Coast Highway) is an option.
NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Riding a bike on a highway is ilegal! dont do it!
Highway 101 starts from north san francisco and ends at north san diego. It is about 420 miles.
You can take highway 101 From San Deigo to San Francisco but it will you much longer than the I5 route. I don't take the i5 route anymore because LA is a nightmare. Highway 101 is nicer. You can even see Lego Land on that route.
Take U.S. 101 NORTH to SR-128 WEST to FT. BRAGG and MENDOCINO.Turn left off the exit ramp onto SR-128 WEST. Follow SR-128 WEST to HIGHWAY 1 (Pacific Coast Hwy). Go straight onto HIGHWAY 1 NORTH.Take HIGHWAY 1 NORTH to Mendocino.
Like Route 1, 101 and 66 in the US, the Aussies also have a few legendary highways. No comprehensive plan for a National Highway system was put into place until 1974 when connectivity was finally worked out at a political level. Perhaps the first highway with a purpose in Australia was created during WWII to defend against potential Japanese Invasion. The Stuart Highway created a North-South route across the continent and deserves the title of the Main Highway. Other routes claim primacy and a few have genuine claims. Until you travel them and meet up with a road train. no concept of the Australian Highway System makes any sense at all. As a footnote, US Route 66 never went from coast to coast, It never went to either coast. It stopped short of the Pacific, and its Easternmost terminus was Chicago. So much for a claim to history.
