Their report advises against construction,but suggests that This matter may, however, properlybe reviewed when mechanical power is more generally sub-stituted for animal power since such substitution will doaway with some of the existing obstacles to successfuloperation, and will render possible shorter and less expen-sive approaches with steeper grades. In 1911 a plan was prepared also by the City Engineerfor a tunnel from the corner of Atlantic avenue and Com-mercial street in Boston to the corner of Lewis and Sumnerstreets in East Boston. This plan was designed to have. FIG. 30.— PLAN FOR A TEAMING TUNNEL AND FOR SUBWAY EXTENSIONS. no grade steeper than 2 per cent and to depend upon ele-vators at each end, with no grade entrances. The plancalls for a 17-foot roadway and two 5-foot sidewalks. As a direct connection between the two districts nowserved by the ferries, a tunnel with outlets at the marginalstreets at each end would serve much better than a bridgeon a high grade. The cost of one or more tunnels largeenough to meet all present requirements would be muchless than the cost of a high bridge. The annual cost of theupkeep of a tunnel would be much less than that of abridge. The exposure to rough weather on a bridge isnecessarily objectionable, while the tunnel would be at alltimes protected. The objections to a tunnel on account of Development of East Boston. 95 light, air and sanitation have been successfully met inEngland and can be met here, and even if a high bridgeseemed more desirable the
