The “Official Projects” series is a collection of projects by MBTA, MassDOT and other municipal agencies. They can be anything related to the T and capital projects: From system infrastructure and accessibility updates, to bus lanes and transit priority, to transit expansion projects. (Not all of them are in the series yet, but I may add these topics sooner or later depending on my own interest and priorities.)

This page gives an index to all such categories.

This page and all subpages listed below are constantly expanding. Check back later and you may see more updates!
