A truck is being held up by its bumpers after a sinkhole appeared overnight at the corner of Brock and Sprague Streets.

As of 10 a.m., city crews had already plowed back snowbanks, and were preparing to dig down to find the exact cause of the sinkhole.

Pieces of sidewalk and roadway were crumbling around the deep hole, as the underside of pavement and concrete could be seen hanging in mid air.

The intersection is supposed to open late Friday evening, but will have to be closed again on Saturday.
