Someone passing by the dispute on the eastbound McKee Road off-ramp called police just before 2 p.m.
Police found the man suffering from several stab wounds and took him to the hospital with life-threatening injuries, police Sgt. Ronnie Lopez said.
However, a doctor said the victim was in stable condition after a surgery was performed, Lopez said.
The suspects fled the scene before officers arrived.
The California Highway Patrol closed the off-ramp until about 5:30 p.m., while police investigated the scene.
