Maintenance
Frequent California landslides and erosion along the coast have caused portions of Highway 1 to either be closed for long periods of time, or be re-routed entirely. Some of these examples include:
- A segment right along the coast between Pacifica and Daly City in what is now Thornton Beach was damaged and rendered unusable after a 5.3 magnitude earthquake on March 22, 1957. Highway 1 was then eventually re-routed to turn inland to join Interstate 280.
- The Piedras Blancas Realignment Project plans to re-route the road up to 475 feet further inland to avoid the expected coastal erosion from the Piedras Blancas Lighthouse to the Arroyo de la Cruz Bridge in San Luis Obispo County.
- The Devil's Slide area has been prone to major landslides. One in 1995 caused the road to be closed for five months, while another in 2006 led to a four-month closure. A tunnel to bypass the area is scheduled to open in late 2012.
- Major reconstruction is planned between Muir Beach and Stinson Beach, including the addition of a 523-foot-long, 20-foot-high, but mostly buried, retaining wall. This follows a four-month, $25 million reconstruction that repaired damage from a 2007 landslide.
- A March 2011 landslide in the Big Sur region forced the highway to be closed for several months. A section south of Lucia that is also prone to frequent landslides, known as Pitkins Curve and Rain Rocks, is being rebuilt as a bridge and a covered rock shed.

Famous quotes containing the word maintenance:
“It is an injustice that an old, broken, half-dead father should enjoy alone, in a corner of his hearth, possessions that would suffice for the advancement and maintenance of many children.”
—Michel de Montaigne (1533–1592)
“My course is a firm assertion and maintenance of the rights of the colored people of the South according to the Thirteenth, Fourteenth, and Fifteenth Amendments, coupled with a readiness to recognize all Southern people, without regard to past political conduct, who will now go with me heartily and in good faith in support of these principles.”
—Rutherford Birchard Hayes (1822–1893)
“In public buildings set aside for the care and maintenance of the goods of the middle ages, a staff of civil service art attendants praise all the dead, irrelevant scribblings and scrawlings that, at best, have only historical interest for idiots and layabouts.”
