A portion of the embankment on MS26 in George County Mississippi failed after heavy rains and flooding caused by Hurricane Ida. It created a hole about 20 feet deep and 50 feet across late on Monday night, and I can imagine it was difficult for motorists to see until it was too late. There were approximately 7 cars that fell into the crater, 2 fatalities, and 10 injuries with 3 of those listed in critical condition. More info at the Sun Herald. Credit to the Landslide Blog.
A report has been released by the NYSDOT on the Scoby Hill Landslide which has impacted a 4.2-mi improvement project of Route 219. The report, dated May 20, 2008 was headed to an FHWA peer review panel.
The Feds were call in to help because of the unusual nature of the landslide. The slip surface is very deep, approximately 30-m (100-ft) below the surface and below all of the design phase investigations. And the remolded shear strength of the silty clay forming the slip surface was only 12-14 degrees.
