The discovery of more problems is delaying the reopening of Big Dig tunnels that were closed to traffic after falling ceiling panels killed a Boston motorist earlier this month, Gov. Mitt Romney said.
On Monday, inspectors found three loose bolts in a ceiling panel in the westbound entrance to the Ted Williams Tunnel. Authorities diverted traffic around the questionable panel and shored it up with a portable support.
Parts of the underground highway system have been closed since several 3-ton concrete panels crushed a car July 10, killing 38-year-old Milena Del Valle.
