Crews Finish Installing 25,000 Support Straps For Big Dig Tunnel Lights
BOSTON (AP) -- Transportation officials have finished installing support straps on the 25,000 light fixtures in Boston's Big Dig tunnels as a safety precaution.
Two straps have been installed on every light fixture in addition the stainless steel clips that secure the 110-pound
fixtures.
The Department of Transportation says the straps were installed to prevent any lights from coming lose because of corrosion.
Earlier this month, a light fixture in one of the tunnels was replaced after it was found hanging dangerously from one side.
The straps are a temporary and are expected to be in place for 3 to 5 years while engineers develop a long-term solution to the corrosion.
