A dangerous problem is getting worse. A sinkhole is expanding in a busy section of east Baltimore. It’s causing all kinds of frustrations. Mike Hellgren is following the repair efforts. From Sky Eye Chopper 13, you can see how much the Monument Street sinkhole has expanded. It’s still not stable and is so dangerous, crews can’t measure the exact size. “It’s quite a challenge for us to come up with a design, especially with the road continuing to erode and collapse,” said Rudy Chow, Department of Public Works.
