Stretch Has History Of Serious Crashes
Alameda de las Pulgas and the Highway 92 offramp, where yesterday's collision unfolded, have a recent history of serious wrecks. A crash at the same intersection on July 31, 2025, killed a motorist and injured two children, according to the San Francisco Chronicle. That earlier wreck revived calls for a safety review of the offramp, an issue traffic officials have repeatedly revisited as they consider possible fixes.
