A water main break has shut down one lane of traffic along Pacific Highway and Palm Street in the Midtown area of San Diego.
Water began flooding the street just before 5:30 a.m. Wednesday in an area near rental car and airport parking lots serving Lindbergh Field.
Early reports said the water was flooding the sidewalk and may have been causing a sinkhole.
An NBC 7 news crew was first on the scene and spotted water bubbling up by small palm tree near the entrance to Budget Rent-a-Car.
San Diego police officers taped off the area and warned television news crews that the area could sink.
As of 7 a.m. , Pacific Highway through the railroad tracks was closed to traffic.
Palm Street was closed from Kettner to Pacific Highway.
The closures made it difficult for Budget customers and shuttles to get in and out of the company's parking lot.
Brett Thomas, Budget’s Director of Facility and Fleet, wondered aloud who was going to foot the bill.
“Quite frankly this water main has had trouble before, so they've worked on it extensively, and the question is, what are they going to have to do to correct it,” he asked.
Officers say they don't have any idea how long this will be an issue.
Water has been shut off to customers in the immediate area police said.
