Only the approach trestle on the station end is that recent. The bascule bridge itself goes back to the opening of the previous North Station/Boston Garden complex in 1928.
The 1928 North Station -- which was actually North Station #2 -- was built on the site of an older Fitchburg RR facility that had become the first North Station, and an older drawbridge over the Charles was replaced by four parallel bascule spans carrying two tracks each. Two of them were removed in the late 1950s when the number of station tracks was cut roughly in half, leaving the two that are there today. On January 20, 1984 a fire burned the wood pile trestle on the station end but did not affect the steel drawbridge. As Mr. Paniagua notes, that led to the temporary closing of the station while the trestle was rebuilt, and the MBTA also used that opportunity to rebuild the platform area, which of course was again reconfigured with the construction of the current North Station #3 that opened in 1995.
