Can the Northern Avenue Bridge be saved? And at what cost?

The bridge, beloved by the preservation-minded, is a swing span that moves horizontally to let marine traffic pass. It has now been left in the open position.

Concepts and cost estimates the city has been reviewing to rebuild the Northern Avenue bridge:

Over $70m

Rehab as a raised/stationary bridge: two lanes for cars in each direction, plus one lane in each direction for pedestrians and cyclists. This option involves the most preservation.

$45m-$60m

Build a new stationary bridge with two sidewalks and two lanes for cars.

$35m-$45m
