What Boston-area transportation projects would you most like to see finished?

Gov. Charlie Baker announced on February 8 that the Longfellow Bridge between Boston and Cambridge would fully reopen in May after several years of renovations

The announcement is welcome news—the renovations has caused regular traffic congestion and re-routing of Red Line service—and it also got us to thinking: What are some other transportation projects in the Boston region that need to hurry up and come to fruition?

We’re not necessarily talking about blue-sky ideas such as an aerial gondola in downtown Boston or underwater parking garages. It’s the more achievable stuff: The North Station-South Station connector; the Blue Line to Lynn or the Red Line to 128; tap-and-go for T fares.
