Entire Green Line Extension from Medford to shut down for 15 entire days to fix slow zones at Haymarket.
This covers December 6 to 20, 2024, so that it's shut down for the entire holiday shopping season and students are at school; but reopens right in time when everyone has left for break and the holiday season is about over.
It'd make a lot more sense to do this shutdown between like January 3 to 18 instead of December SMH (or July for that matter, but the Red Line had higher priority).
