2:11 p.m.: Caltrans crews are continuing to investigate and fix a sinkhole on Interstate 5 in the Tracy area Wednesday afternoon.
Skip Allum, with Caltrans District 10, says maintenance crews discovered the sinkhole Tuesday morning located on the shoulder of northbound I-5 just south of Highway 33.
The hole was initially one foot in diameter and 10-foot deep.
Allum says crews discovered a 40-year-old abandoned irrigation pipeline in the area and may have been the cause of the sinkhole.
But crews are continuing to investigate by exploring and digging up the road, says Allum.
"Right now they're still digging around the area to see if there's anything else that they should be aware of," he says. "They can then remedy those things and begin the repairs."
The road is expected to reopen Thursday afternoon.
Motorists are being asked to take a detour toward eastbound Highway 132, to northbound state Route 33 and back to northbound I-5.
