Answering my own question, bit by bit: It looks like there have in fact been improvements in tunnel creation in the last 50 years. Examples:
- NYC Third Water Tunnel, under construction since 1970. 24 deaths, the vast majority of which were decades ago as safety improved. In fact, the first tunnels were blasted and drilled; the newer ones are made with a boring machine.
- St. Gotthard Road Tunnel, 1969-1980, just one lane in each direction and 2 deaths per mile. A comparable transportation tunnel today in the area is the Gotthard Base Tunnel, 0.2 deaths per mile.
- Older tunnels apparently caused thousands of workers to die due to silica exposure.
It also seems that tunnels are more dangerous than roads per mile by many orders of magnitude. For example, the aforementioned Gotthard Road Tunnel had over 875 accidents and 30 deaths in a span of just 24 years.

Pollution from congestion probably has at least a similar impact in terms of premature death and debilitating disease. Edit. Down votes for stating that pollution from congestion causes premature death and serious health effects - yikes! Is that even a disputed fact? Google is full of academic papers on the very subject. The first result I see talks about congestion pricing having a massive impact in London. I would argue that congestion relief from the construction of tunnels would have a similar impact. http://oem.bmj.com/content/65/9/620.short http://oem.bmj.com/content/65/9/620.short - "Predicted benefits... were 183 years of life per 100 000 population... In London overall, 1888 years of life were gained."
