An estimated 1 million people are expected to line the 26.2-mile course of the 119th Boston Marathon on Monday. Security will be tight, as it was last year, with checkpoints and uniformed and plainclothes officers along the course. Some roads and MBTA stations near the course will be closed. Here are some of the things you should know to navigate Marathon Monday smoothly.


Boston Athletic Association and MBTA officials are strongly encouraging spectators to use public transportation to avoid traffic congestion. To accommodate the swell of commuters, the T will be operating on a rush-hour schedule before and after the race. Those hoping to snag a coveted position at the finish line will have to work around the closing of some stations. Copley and Arlington stations will be closed all day, and the stops at South Street, Kent Street, and St. Mary’s Street on the C Branch of the Green Line will be closed between 10 a.m. and 6 p.m. MBTA officials recommend taking the Green Line to Hynes Convention Center or Prudential Center and walking until you find a spot. Buses will be operating on a normal weekday schedule, but will have detours for stops nearest the race’s course.

Bicycles will not be allowed on the MBTA Sunday and Monday.


Road closures and parking

Parking will be free throughout Boston on Patriots Day, but spots will probably be filled early. Roads along the course will be closed and heavy traffic is expected throughout the day. Public transportation is the more efficient and cheaper option. MBTA parking garages will be pay-on-entry and cash-only to expedite service and are expected to fill much more quickly than usual.


According to Boston Athletic Association officials, spectators should expect a significant presence of uniformed and plainclothes police officers along the race course. Security checkpoints will be in place along the route, though their locations have not been disclosed.


Spectators are advised against carrying bags, and those who do may have them searched by security officials. If you need to bring something, carry it in a clear plastic bag or in a purse smaller than 12 square inches.

What to wear

The weather forecast calls for temperatures in the 40s and showers in the early afternoon, turning to heavy rain by about 4 p.m. Rain jackets or ponchos are in order, but be aware that face coverings and bulky clothing are banned alongside the race course.
