Talk:Chelsea Street Bridge (Boston)

Chelsea Creek Bridge
Is this the same bridge? I see, in the Grand Junction Railroad and Depot Company article, that it says "On February 28, 1955 the counterweight fell off the Chelsea Creek drawbridge, taking the bridge permanently out of service[...]". Is that bridge this one's predecessor? - Denimadept (talk) 05:11, 12 January 2015 (UTC)
 * No, that was a separate railroad bridge parallel to this one. Pi.1415926535 (talk) 05:53, 5 August 2018 (UTC)

Old bridges
Every source I can find says that the previous bridge was built in 1936, or built in 1900 and rehabbed in 1936. But maps both before and after 1900 show the bridge well south of the railroad bridge - where this abutment still stands - and it's pretty clear that a bridge at the modern alignment wasn't there until 1936. A bridge on the old alignment was definitely destroyed in 1908. So when were bridges on the old alignment built, and how many different ones were there?

 * I found fairly detailed historical info. on the previous bridges in the 1997 Historic American Engineering Record report on the then-current bridge, which it says was built in 1936–37 and opened in May 1937, and I have now added that report as a citation. (And year of completion is normally used when giving only a single "year built" for a building or bridge, so in this case it's "1937" or "1936–37", not 1936.)  Additional info. on the earlier bridges can be added from that (I am not interested in doing so myself), but I have not checked to see if it answers your specific question. – SJ Morg (talk) 06:32, 5 August 2018 (UTC)
 * Thank you - that was exactly what I was looking for! Pi.1415926535 (talk) 06:37, 5 August 2018 (UTC)
