The design process is nearing completion for the upcoming replacement of the North Washington Street Bridge (aka, the Charlestown Bridge). Final design issues and construction impacts were reviewed by State and City officials at a December 16, 2015 meeting held at the West End Museum. The complete meeting video is shown above (timeline below).

Work is expected to commence in early 2017 with a 3-4 year construction period. The $125 million project is being funded primarily by Federal Highway and State budgets. The general design of the new bridge has not materially changed from what was presented earlier in the year at neighborhood meetings.
The new bridge has a modern “tuning fork” design that takes its cues from the nearby Zakim Bunker Hill Bridge. The existing bridge was built in 1898 and the center span closed in 2003 for safety reasons. The new bridge has been characterized as “Zakim-lite” from a design standpoint. While the Zakim is an interstate bridge, the new N. Washington Street bridge has been designed to be more of a community connection between Charlestown and the North End / Downtown Boston.
With four lanes of vehicle traffic (two in each direction), much of the new bridge span will be dedicated to bicycling and pedestrian access. During construction, the bridge will remain partially open to traffic with 2 inbound lanes and 1 outbound. Once complete, the new bridge will feature bicycle cycle tracks and dedicated pedestrian zones and center viewing areas along the Freedom Trail. Vehicle traffic will continue the existing pattern of merging three lanes from the adjacent Charlestown and downtown intersections down to two lanes in each direction on the bridge itself.
The recently reopened Harborwalk under the N. Washington Street bridge will be closed again during construction. It will also be reconstructed at a higher elevation so that the consistent flooding problem will be resolved. Public Works also plans to reconstruct the existing utilities and pipes under the bridge.
Public comments covered a wide range of issues at the meeting including:
- Concerns regarding Constitution Marina and other nearby business/community interests
- Requests for dedicated public bus lanes
- Requests for cycle track continuation through Keany Square on the downtown side
- Comments regarding the lack of preservation of the current bridge
- Closing of the harborwalk under the bridge
- Traffic congestion as a result of pending area development
Designers have released a 3D animated video with day and night renderings of the new bridge, shown below. At night, the new N. Washington Bridge is expected to be lit similar to the Zakim Bridge.
