Pacific Coast Highway Lane Closed Indefinitely After Major Crack Appears in Cliffside

A prominent section of California's Pacific Coast Highway (PCH) has been closed indefinitely due to a substantial crack that appeared in the cliffside beneath the roadway, raising concerns about landslides and the structural integrity of the iconic route.

The deep fissure was observed on Tuesday along the PCH between El Morro Canyon and Irvine Cove. The crack has extended close to the edge of the cliff and the highway itself, prompting the California Department of Transportation (Caltrans) to close the right lane to ensure public safety, according to CBS News.

Officials have indicated that the lane closure is expected to last longer than a few days. "Stabilizing a coastal slope is complex," said Laguna Beach Communications Manager Laura Ezzell. "Residents should plan for the lane closure to last well beyond the next few days." While the crack is located outside of Laguna Beach's direct jurisdiction, city officials are monitoring the situation closely due to its potential impact on residents.

A Caltrans spokesperson confirmed that the lane closure will remain in effect until repairs are completed. "We are currently coordinating with our partners to evaluate current conditions. Caltrans is reviewing updated surveys and drone footage to determine the most effective path forward," the spokesperson stated.

The affected stretch of highway is situated between the affluent areas of Newport Beach and Laguna Beach. Residents have expressed concerns that the eroding cliffside could lead to a landslide, with visible pieces of dirt falling into the ocean below.

"The cliff side right here this close to PCH is falling… that’s why all this water is so brown," local resident Blair Conklin told Surfer. "My guess is because the cliff is eroding so bad… it might be at risk of having part of PCH crumble into the ocean."

This geological instability is believed to be exacerbated by recent severe weather, including Tropical Storm Rachel, which brought heavy rains and powerful waves. The storm also caused significant damage along the coast further north, battering waterfront properties in Long Beach and flooding other coastal communities like Laguna Beach.

Roughly 15- to 20-foot backwash waves breached seawalls and sand dunes in the region during the storm. Chris Monroe, who documents local events, described the ocean surge as unprecedented, noting, "The ocean is literally in the city right now. I’ve never seen water push this far up into Laguna in my life."

Officials attributed the destructive weather to a combination of high tides, historic ocean surges, and the tropical storm's impact. As the El Niño weather pattern continues to strengthen, other coastal areas in California are bracing for a potentially challenging storm season.

In response to coastal erosion concerns, Caltrans is implementing measures such as placing boulders along State Route 1 in Ventura County to reinforce the roadway. Additionally, California State Parks have temporarily closed sections of Crystal Cove State Park and San Onofre State Beach due to damage from high surf.
