News Summary: Japan public works showing age
TUNNEL TROUBLE: The collapse of hundreds of concrete ceiling slabs in a tunnel outside Tokyo is raising calls for more spending on Japan's aging infrastructure, but the country might not have the money.
DEADLY DISASTER: Nine people were killed Sunday in the tunnel, a major link between the capital and central Japan that opened in 1977 at the peak of the country's postwar road construction boom.
DIGGING DEEPER: The transport ministry ordered inspections of 49 other highway and road tunnels. Much of Japan's transportation system may require refurbishing after years of spending cuts that starved projects of funding.
