Boston's Six Biggest Megaprojects, and Which Ones You Should Actually Pay For

Six projects are reshaping which Boston neighborhoods will be desirable in a decade. Most of the content written about them is promotional, produced by people with something to sell nearby. Here is where each one actually stands, and what that means for what you should be willing to pay today.

Suffolk Downs

The largest one. The former racetrack on the East Boston–Revere line, 161 acres, being converted over a decade-plus into 16 million square feet of mixed-use space: 10,000 housing units, offices, hotels. Expected build-out around 15 years.

The first residential building, Amaya, was completed with 475 units. And the honest status: housing construction at the site has been paused, though day-to-day project operations continue.

A pause inside a 15-year program is not a collapse — 10,000 units is a program, not a project, and it moves in phases that respond to financing conditions. But if you bought in East Boston in 2023 on the theory that Suffolk Downs would transform the neighborhood by now, that thesis has slipped.

The real read: this was never a story about the site. It is a story about East Boston being re-rated as core Boston, with Blue Line access that is often faster than the map suggests. That re-rating proceeds with or without the next building.

The I-90 Allston Multimodal Project

The most underappreciated project in the city, and the one carrying the most uncertainty.

It replaces a structurally deficient elevated highway, straightens the Turnpike through the old Beacon Park Yard, restores Charles River access for Allston, and includes a new transit hub at West Station.

Then federal legislation enacted last July eliminated billions in unobligated Reconnecting Communities funding, including all but $8 million of a $335 million grant for this project — roughly 17 percent of total project cost. MassDOT is running an independent cost and engineering analysis, expected to complete by the end of this year. Advocates have asked the state to evaluate scenarios with no layover at Beacon Park Yard and fewer tracks at West Station, which tells you the direction of the conversation.

On West Station itself: as of this year, plans have not advanced beyond conceptual studies, and the planned opening is 2040. Harvard has pledged $90 million toward its construction, which is a real commitment. But a station proposed for over a decade with a 2040 date is not something to pay a premium for in 2026.

White Stadium

The city is rebuilding White Stadium in Franklin Park as a Boston Public Schools athletics facility and the home of Boston Legacy FC, splitting a $325 million cost between the city and the club.

Status: demolition and abatement complete, foundation and utility work done or underway, vertical construction on the grandstands started this spring with steel following. The city has targeted a summer 2027 opening, though there are real questions about whether that arrives in time for the team's season. The project has committed $43 million in contracts to MWBE businesses, 44 percent of contracts awarded to date.

The legal fight is effectively resolved. In August the Massachusetts Supreme Judicial Court ruled the city can continue building, rejecting the Emerald Necklace Conservancy and Franklin Park Defenders challenge and finding the plaintiffs lacked standing on the charitable trust claim.

The real read: the largest investment in Franklin Park's history, affecting Roxbury, Jamaica Plain, Dorchester, and Mattapan. Those neighborhoods still price under the state and municipal down payment assistance caps. A functioning stadium plus major park investment plus assistance eligibility is a combination with a shelf life.

South Station Tower

Included deliberately, because it is the control case. Fifty-one stories, 677 feet, built over the historic South Station complex. Construction began January 2020 and finished last September; the expanded bus terminal opened in late 2023. Now the sixth-tallest building in Boston.

Five and a half years, on a site already owned, already zoned, already funded. Keep that number in mind the next time someone shows you a rendering of something that has not broken ground.

Dorchester Bay City

Redevelopment of the former Bayside Expo site near UMass Boston, with updated plans replacing car-oriented uses with pedestrian and bike infrastructure and better connections to Dorchester, UMass Boston, and the harbor.

Long horizon, waterfront parcel. Apply the coastal flooding questions accordingly — Boston's Coastal Flood Resilience Overlay District deliberately extends beyond FEMA's mapped areas, and elevation and mechanical placement are the questions that matter in any large waterfront build.

The Red Blue Connector

The Red and Blue Lines are the only two MBTA subway lines without a direct connection. The connector would extend the Blue Line about 0.4 miles west from Bowdoin to Charles/MGH, eliminating Bowdoin, with estimated daily ridership around 12,000.

An underground connection between these lines has been under consideration since the 1920s. It gained serious traction in the early 1970s. Design has been funded. Status: proposed.

Fifteen hundred feet of tunnel and a century of discussion. If built, it meaningfully changes East Boston, Beacon Hill, and the Blue Line corridor. Do not buy on it.

The rule

Never pay today for a project that has not broken ground.

There are two categories on this list. Projects physically underway, where steel is going up — White Stadium, South Station Tower. And projects that exist in renderings, community meetings, and funding announcements — West Station, the Red Blue Connector.

The market prices the second category anyway. That is the trap. Listing agents talk about the coming transit hub and the planned transformation, and buyers pay a premium now for something with a 2040 date and no construction contract.

The money in Boston has historically gone to people who bought in neighborhoods improving for reasons unrelated to any megaproject, and treated the megaproject as free optionality.

Three questions for any project attached to a property you are considering:

  1. Has it broken ground? Not approved. Not funded. Broken ground.
  2. Is the funding secured, or was it recently rescinded? Ask specifically — the Allston project lost 17 percent of its cost in a single federal bill, and marketing material has not caught up.
  3. What is the stated opening year, and how many times has it moved?

Transit access changes value faster than finishes ever will. That is true, and it is why these projects matter. But it is only true once the transit exists. A station opening in 2040 does not help you sell in 2032.


If you are looking near any of these and want a read on whether the premium in the asking price is justified by where the project actually stands, send me the address. I follow these closely and I will tell you what is real and what is a rendering.
