Pfeiffer Canyon Bridge collapse, Big Sur (2017)
A winter storm damaged the Pfeiffer Canyon Bridge on Highway 1, the only road into Big Sur, splitting the community. Caltrans demolished the cracked bridge and rebuilt a replacement over the canyon.
Highway 1 reopened in late 2017, about nine months after the closure.
Big Sur's dependence on a single road became a recurring problem, with repeated closures in following years.
Like Highway 140, a single mountain road served as the only route into a region; recovery required an engineered fix lasting months and costing tens of millions.
