Mexico experts: Outdated drain caused July’s deadly sinkhole
MEXICO CITY — A panel of experts in Mexico has determined that an old drainage pipe was to blame for a sinkhole on a major highway that killed two men last month when their car plunged into it.
The 34-year-old drain was not replaced as suggested before an expanded highway was built on top of it, the experts concluded in a report released Thursday.
The drain became clogged, and water backed up and apparently washed away the earth beneath the road.
Clemente Poon, Mexico’s highways director, cited “mistakes and omissions in the supervision and building” of the highway expansion.
