1800s+1902+1936+2004+2017 MA-3A Fore River Bridges at Quincy, MA

1800s: (Bridge Hunter)
1902: (Bridge Hunter) The 1902 date is from HAER-data, Bridge Hunter has 1905
2004: (Bridge Hunter)  Bridge Hunter says 2006, but that is wrong.
2017: (Bridge Hunter; no Historic Bridges; 3D Satellite)

This is another crossing that shows all three of the typical moving bridge designs: swing, bascule and lift.

The bridge was removed in 2018 after the 2017 bridge opened. Obviously, this bridge was built to carry the traffic of  MA-3A while the 1936 bridge is replaced.

Google Earth caught the temporary bridge before the 1936 bascule bridge was removed. Unfortunately, the image is of poor quality. I don't know why Bridge Hunter gives a date of 2006 because an Apr 2005 image shows most of the 1936 bridge is gone. Also a comment on Bridge Hunter indicated it was built 2002-04.

The replacement bridge is a four-lane lift bridge.

John Childs' comments on BridgeHunter-2017 explains that the installation of the lift span was delayed because they first had to fix problems with lift mechanism components.

Thanks to Mike Cavanaugh for a neat pic of the lift span section of Massachusetts' Fore River Bridge jacked up and ready to install.
