MBTA Bus Route 80

This bus goes to Lechmere, Somerville, Medford, and Arlington. Therefore it is useful if you want to go to any of those places. It is relatively unuseful if you want to go to other places such as Watertown, Braintree, Philadelphia, or Nebraska, unless you are starting nearby the bus.
The bus runs relatively infrequently compared to other buses because it has modest ridership. The bus is usually not overly crowded.

I have mixed feelings about the 80 bus, depending on the season. In the fall, the 80 was my knight in shining armor. Always on time, always consistent. And then came the blizzards. And more blizzards. And the 80 bus just couldn’t make it through the narrow and snow-​lined streets on time. I was late to work (in Winter Hill) almost every day for a month, so I’ve resorted to taking the 89 from Sullivan :(
In nice weather, the 80 is awesome but I wouldn’t depend on it when the weather is bad.

The hidden jewel of Somerville bus lines. Worth 5 stars for the front half of its outbound route alone, which runs up the valley between Spring and Winter Hills via Pearl Street and Medford Street, before dumping onto Broadway, running through Ball Square, before slingshotting out around the backside of Tufts to do an end run via High Street in Medford up to Alrington Square. A ride on this reliable and off the beaten path route will take you directly to the best pizza in Somerville (the Paddock), will dump you in front of the Cock Block (Woody’s, Wang’s and Pini’s) at Magoun Square, and dump you in Ball Square so you can get some REAL kick ass cupcakes at Lyndell’s.
I don’t take this out much past Powderhouse, but it’s a nice semi-​scenic longway alternative to get to Arlington if you don’t want to deal with tempestuous 87.
