The ground collapsed outside the gates surrounding construction of the downtown underground parking structure in Ann Arbor around 3:30 p.m. Thursday, following a breach in the north earth retention wall. The accident caused a 40-foot-deep sinkhole behind the Earthen Jar restaurant, 311 S. Fifth Ave. Both Earthen Jar, a mostly vegan Indian restaurant, and Jerusalem Garden, a falafel joint next door, had to close for business and evacuate. This was the scene as crews worked through the night in the area. The $50 million parking structure is a project of the Ann Arbor Downtown Development Authority. Read the story here.
