COMMONWEALTH’S MOST POPULAR Codcast of 2021 was recorded in 2018.

The interview was with Fred Salvucci, the former secretary of transportation, who made the bold statement that the proposed West Station commuter rail stop was needed then to deal with existing congestion on the Massachusetts Turnpike and in Kenmore Square — not future congestion caused by Harvard University’s creation of a new neighborhood in Allston. 

West Station is no closer to actual construction 3½ years later, but the debate about when it should be built has quieted. In 2018, the Baker administration insisted there wouldn’t be enough riders to justify the station until 2040 at the earliest — after Harvard’s plans for the area are fleshed out more. 

Salvucci and other transportation advocates disagreed. “The demand is there. It’s not a theoretical thing. You can count the building permits,” he said on The Codcast. “Those commuters are coming and there’s no space for them on the Turnpike.”

The debate has subsided amid the COVID-induced downturn in traffic and the preoccupation in recent years with another key element of the I-90 Allston project — how to replace a deteriorating elevated section of the Turnpike near Boston University. That issue is now seemingly resolved, which may explain why Salvucci’s 2018 interview continues to attract listeners in 2021.

The wide-ranging interview with Salvucci also contains his tips on how to improve Silver Line service in the Seaport (he favored a tunnel under D Street, which hasn’t been embraced), opposed congestion pricing (which hasn’t gained traction), and said he will never take an Uber or Lyft because the companies don’t provide health care to their drivers and the apps pull passengers away from public transit. 

The Salvucci Codcast had the most plays in 2021, according to CommonWealth’s podcast carrier, SoundCloud. Here, in reverse order, are the top 10 Codcasts of 2021 along with links to the audio files and the stories we wrote about them.

He also became the first to drop out, announcing this morning that he is ending his campaign.
