Runoff from recent torrential storms that drenched the Mountain Area caused at least three to four feet of soil erosion underneath Highway 41’s northbound lanes, Caltrans workers said Friday afternoon, after they discovered the problem between Road 426 and Highway 49 in Oakhurst.
One lane traffic control was instituted by California Highway Patrol officers around 1:30 p.m. on the eastern northbound lane, for about 300 feet until the issue is fixed.
Adam Wimberly, maintenance supervisor for Caltrans District 6, said depending on the scale of the work, crews may be present 24 hours a day, with the repairs completed by tomorrow afternoon.
“We’re going to saw cut out the asphalt above it so we can fix the hole, repair it, fill it with base rock, compact it up, then put asphalt back on top,” Wimberly said.
Wimberly said Caltrans has seen similar erosion in the Mountain Area.
“We’ve been getting some serious rain off and on which can do this,” Wimberly said. “It’s part of living in the hills.”
CHP Sgt. Michael Schwab said it was fortunate the worn away soil was found before it became something worse.
“It’s definitely good this was caught,” Schwab said. “Sometimes you see sinkholes on the news, but this was contained before that may have taken place.”
“Be careful, follow traffic signs, be patient, and drive with caution,” Wimberly added to drivers.
