The crack has led to significant traffic disruptions along the Pacific Coast Highway, a major route in Southern California. The closure of the southbound lane is causing delays and inconvenience for commuters and residents in the area, including those near El Morro Elementary School. The crack also poses a risk of further slope erosion, which could lead to more extensive damage to the highway and surrounding areas. The situation is exacerbated by the ongoing 'super' El Niño weather conditions, which have already caused coastal erosion, high tides, and damage to infrastructure along the Southern California coastline.
