Eric Goldwyn, Alon Levy, and Elif Ensari host their first webinar on transit-infrastructure costs. In the webinar, they present an overview of their research project on transit-infrastructure costs, a detailed case study of the MBTA’s Green Line Extension, and engage you in a conversation moderated by Matthew Yglesias, the author of One Billion Americans and co-founder of Vox.

This is their first time discussing their case study on the Green Line Extension, which includes more than 40 interviews with people connected to the project, a review of Green Line Extension documents, and historical context on transit-infrastructure costs in the Boston area.

If you’re curious about why it’s so expensive to build transit infrastructure in the United States and how their research tackles this issue, please watch this video and view transitcosts.com.
