Crews are rapidly addressing a significant rockslide that blocked Highway 140 and threatened access to Yosemite National Park. The rockslide, which involved hundreds of tons of debris, occurred last Monday night, leading to temporary closure of the essential route. Authorities, including Caltrans, are working round-the-clock to ensure that at least one lane will be open by week's end. In an effort to mitigate further hazards, geologists have utilized drones and specialized contractors employed inflatable airbags to remove loose rocks. The main construction team has now started debris removal operations, addressing roadway damage as well.
Crews are currently engaged in a 24-7 operation to clear the rockslide, which closed Highway 140, an essential route into Yosemite, reducing long-term closure fears.
Geologists utilized drones to create 3-D imagery of the cliffs above Highway 140 to identify potentially hazardous loose rocks for removal.
Safety concerns prompted specialist contractors to deploy inflatable industrial pillows to dislodge unstable boulders from the cliff before main debris clearance could begin.
Teichert Construction has begun hauling away debris from the highway, with expectations of reestablishing at least one lane by week’s end.
