Map with all coordinates: The Thomas P. O'Neill Jr. Tunnel is a road tunnel in Boston in the state of Massachusetts of the United States . It was named after the politician Tip O'Neill and built as part of the Big Dig . Since its opening in 2003, the tunnel with the Central Artery has led the previously above-ground roads I-93 , US 1 and Route 3 now underground under Boston. It roughly follows the original course of the elevated Central Artery , with the access in the north direction offset east to the exit in the south direction to enable an improved connection to the Massachusetts Turnpike . The tunnel extends overall from the borough of South Boston at its southern end to the Leonard P. Zakim Bunker Hill Memorial Bridge at its northern end.
history
The tunnel has been criticized since the construction phase because of the extremely high construction costs. During the construction phase there were also some significant construction defects, because the low-lying side walls, which are up to 120 ft (36.6 m ) below the surface, had to be built as diaphragm walls . However, this work was not carried out adequately, so that the tunnel walls are continuously leaking due to the high groundwater level and water penetrates into the tunnel tube. As a result, in addition to the allegations of corruption and the discussion about the massive budget overrun, there was another controversy about the construction defects.
At the time of its completion, then Governor Mitt Romney proposed that the structure be named the Liberty Tunnel . The Democrats in the state administration and in Congress , however, were against it, so that the tunnel under Section 1930 of the year 2005 by the then-US President George W. Bush signed Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users official after Thomas O'Neill , who was a long-time Speaker of the US House of Representatives .
