Causeway Street elevated

On June 20, 1907, construction began on one mile of elevated track connecting the Canal Street incline to East Cambridge.

The project's centerpiece was the 1,700-foot (520 m) arched Lechmere Viaduct crossing the Charles River; other sections included a short elevated in East Cambridge and an elevated line above Causeway Street connecting the viaduct to the Canal Street incline.

[2] The first streetcars crossed the new bridge and the Causeway Street elevated in revenue service on June 1, 1912, shortening the ten-minute trip from Lechmere Square to the subway to just three minutes.

A short siding off the inbound track south of North Station is used for storing construction equipment.

During the 2004 Democratic National Convention from July 24 to 29, 2004, the disused Elevated was used as a platform for security personnel.
