Comparison between Boston's, New York City's, and European subways and tunnels.











The complexity of the infrastructure on the site is impressive particularly considering that this particular section of the tunnel was built over a century ago. The drawing above shows the intricacies of the late nineteen-century infrastructure in the relationship to subway tunnels.













Tremont Street Section showing the relationship between underground tunnels, adjacent buildings, and below-street-level infrastructure.












During our site visit we were able to investigate existing conditions of Tremont Street Tunnel and to better understand its spatial qualities. In many ways, what we saw exceeded our expectations and gave us a good working data to further develop our ideas.
















Tunnels are not just tunnels. There are also other unique spatial configurations that just make our imagination fly.
