Although the complete project remains on schedule, supply chain delays and bridge construction complexities have delayed opening of the southern barrel. While the MBTA evaluates alternatives to restore rail service as soon as possible, work crews will use this opportunity to accelerate other projects planned for the line.

The drawbridge includes these primary elements:

• Abutments that support the ends of the bridge and transfer the loads from the superstructure into the ground
• Pier structures that extend into the water to support the bridge
• The bascule span, which is the drawbridge over the channel
• The control tower that contains equipment for the draw tender, who operates the bridge

More information about the project and primary elements can be found in the Winter 2021 Fact Sheet.If you have questions or comments, please email the team at GloucesterDraw@MBTA.com.

Crews work to complete the control tower so it’s ready to operate the new bridge. They installed the glass enclosure on the observation level of the tower.
