The streets of Boston are being radically transformed for 30 days as the MBTA Orange Line and part of the Green Line are shut down into mid-September, with shuttle buses being brought in to help replace trains.
The closures will condense years' worth of badly needed repair work, officials have said, but from Friday until Sept. 18, it will cause headaches for commuters — and not just people who regularly ride the T. Street configurations are being shifted around to keep the city running as smoothly as possible.
Here's a look at what to expect, all in one place.

- Green Line Shuttle Bus Route
- Street Closures in Boston
- Expected Traffic Impacts
Orange Line Shuttle Bus Routes
The Orange Line is the first MBTA shutdown coming, beginning Friday night at 9 p.m. Shuttle buses will run for most, but not all, of the route. Riders hoping to get between Government Center and Copley Square will need to take the Green Line, walk, bike, take a bus or a rideshare.

Green Line Shuttle Bus Route
The Orange Line may be shutting down first, but it won't be the only train closure to impact commuters Monday. The Green Line will be closed north of the Government Center Monday through Sept. 18.
Street Closures in Boston
To help shuttle buses get by, a few streets will be closed entirely. Hubs for riders are being set up in Copley Square and Government Center to facilitate easy access for bus routes.
The city of Boston released this list of changes to street layouts:
Street closures:
•Government Center: State Street between Congress and Washington streets
•Copley Square: Dartmouth Street between St. James and Boylston streets
•Jamaica Plain: Washington Street (northbound) between Arborway and Williams Street
Parking restrictions, lane changes: Along the shuttle routes, expect parking restrictions to make it easier for shuttle buses to park and turn — they're bigger than typical MBTA buses, with a wider turning radius — that may limit where drivers can park on the street. "Signal timing adjustments will be made in advance of and during the shutdown to support shuttle movements," the city said on its website, but hasn't released a detailed list.

Expected Traffic Impacts
State officials have said they expect serious traffic on streets in the Boston area, with more vehicles on the road and changes to road layouts to accommodate shuttle buses. Here's how bad it's projected to be:
