BOSTON- BRIDGE PRESERVATION, B-16-236 (39M, 39P, 39U, 39W, 39Y), 5 BRIDGES CARRYING STATE ROUTE 1A (EAST BOSTON EXPRESSWAY NB/SB) AND RAMPS
The project involves preserving bridges B-16-236 (39M, 39P, 39U, 39W, and 39Y) on State
Route 1A (East Boston Expressway) and its ramps in East Boston, Massachusetts. The main goal
is to replace bridge joints, repair deteriorated concrete near the joints, and patch the existing
exterior barriers along Route 1A northbound, the off-ramp, and relevant approaches. Additional
repairs include replacing the wearing surface and waterproofing membrane, as well as deck and
end diaphragm repairs over Route 1A northbound and the off-ramp.
