A sinkhole shut down the transition ramp from westbound state Route 54 to northbound Interstate 805 in National City early Monday.
The sinkhole was discovered around 4 a.m. Video from the scene showed Caltrans workers putting traffic cones around a dip in the roadway about 8 feet wide. Only a portion of the dip had caved in on itself.
The transition ramp was closed for several hours as crews repaired the road. Caltrans reopened the road at about 3:30 p.m.
