Temperatures are expected to rise this weekend as the polar vortex remembers why it’s called a “polar” vortex in the first place. That’s good news for the folks working on the Longfellow Bridge, because they’ll be working hard this weekend during one of the project’s planned service diversions.

As with previous weekend diversions, the only motorized vehicles allowed on the bridge will be MBTA buses running between Kendall and Park St. stations. The detours for motorists remain the same. Here’s a map of those detours, and you can always find more resources at MassDOT’s Longfellow Bridge page.
