The project is currently at the 90% design phase. The 100% design submission is anticipated in July 2015, and advertising in the October of 2015. This is subject to the US Coast Guard (USCG) issuing the required bridge permit. The anticipated construction duration is 4 years.

Only the swing's deck and motors/hydraulics. It's still the same approaches, same pilings, same swing mechanism, same everything else. $23M doesn't buy a full-on replacement of a bridge that big. If it were even replacing the entire end-to-end superstructure that thing would cost a healthy bit more than the Merrimack River Bridge rebuild on the Haverhill Line. This price tag just buys a swing deck, machinery components to swap out, and the scheduled masonry patches to the old piers and corrosion abatement on the approaches.
Rehab contract and the component replacement contract were separate awards. This must mean #2's been awarded if they've scheduled the public meetings for the deck-swap shutdown.

According to the article, piling repairs will begin this spring, with a bid going out now for larger piling work

Hence the "swing span" part. It's also a relatively short one at that compared to most other swing bridges.
All things considered though the T probably would have done well to replace it with a bascule span instead to lower the risk of any barge/boat strikes. The width of the "navigable channel" so to speak in between the two sets of approaches is narrow enough before factoring in the center "resting barrier" for the swing bridge. They've happened before and when they do it only makes for a messy commute. Even the Saugus River draw with its own problems AFAIK hasn't had that issue.

It may even be dense enough boat traffic where it doesn't make a hell of a lot of difference if a replacement movable were any taller than the current bridge. But it definitely would benefit bigtime from doing one of those Amtrak Shoreline-like conversions to a lift center span with double-wide shipping channel.
The MBTA's Fiscal Management Control Board on Wednesday unanimously approved awarding J.F. White Contracting Company a contract for nearly $16.2 million to complete work on the bridge.

I'm also not a fan of the "express bus from North Station to Salem and Beverly". Does this mean there will be no service to intermediate points (e.g. Swampscott, Lynn)?
