Project Description

Design Build (DB) North Station Draw One Bridge Replacement and Associated Track & Signal Upgrades, Boston and Cambridge, MAProject Description

MBTA Contract No. H32CN01

The purpose of the North Station Draw One Bridge Replacement and Associated Track & Signal Upgrades Project is to replace the Draw One Bridge, the Signal Tower A, and associated MBTA track and signal infrastructure. The existing Draw One Bridge consists of two adjacent two-track bridge spans crossing the Charles River. Signal Tower A is located just north of the Draw One Bridge, east of the tracks. Due to the deteriorated condition of the building, a temporary control tower was built in 2018. Conduits below grade connect the temporary control tower to equipment in the adjacent Signal Tower A.

Scope of Work:
The scope of work includes design and construction for:
Staged demolition of the existing draw bridges, approach spans, fendering, and Tower A.
New movable bridge structures carrying six tracks total, including replacement of the north and south trestles and fender system.
Trackwork and associated signals to connect the new bridge tracks to the mainline tracks north of Tower A and the existing station tracks, including reconstruction of direct fixation and platform modifications where required.
Track improvements extending out approximately 1.5 miles from North Station.
Raising and modifying the North Bank Bridge to accommodate the new track alignment.
A new Tower A building, positioned to best serve operation of the proposed new structure. Existing controls would be relocated from the temporary control tower to the new Tower A building.
Replacement of up to three sets of Signal Instrument Houses (SIHs) and upgrades for all wayside devices, cables, and infrastructure serving the existing Draw One Bridge.
New North Station Platform F will be constructed, tying into an existing partial platform, to serve new Station Tracks 11 and 12.
New drainage systems, including water quality structures and new outfalls, on each trestle.
