A sinkhole about 3 feet wide and 2 to 3 feet deep that broke open along Highway 41 in the crosswalk from Coarsegold Market to Coarsegold Historic Village Tuesday evening was repaired by Caltrans maintenance crews, with the southbound lane set to reopen Wednesday night.
California Highway Patrol officers responded to the sinkhole about 8 p.m. Tuesday shortly after the sinkhole was reported. Cones were put in place both by CHP and by Caltrans workers who arrived around 8:20 p.m.
A full Caltrans night crew was called in to assess the area for utility lines and other concerns before work began early Wednesday morning. During repairs, crews placed a temporary steel plate over the hole, eventually digging it out and filling it with base rock before paving over it with asphalt.
No cars were reported damaged as a result of the sinkhole, and drivers in the southbound lane were diverted to the passing lane in order to avoid any traffic delays.
Caltrans spokesman Christian Lukens said though there was apparently a well site around the sinkhole area in the late 1800s, that wasn’t the cause.
“Turns out, at least from what (staff) saw, it was a previously-installed cable fiber line that wasn’t properly finished off,” Lukens said. “It wasn’t compacted down enough, so runoff from rain and whatever else was able to get in there and degrade the road material.”
