Better Bike Lanes: Bike lane types

You can learn about the different bike lane types in the City of Boston below. These bike lane types offer more comfort for people biking. We are working to build new high comfort bike facilities and upgrade existing bike facilities to be more comfortable. For more information on our bike lane efforts, please visit our Better Bike Lanes website.

Traffic-calmed local streets

Traffic-calmed local streets are designed for slower speeds. They also discourage unnecessary through-traffic by drivers.

More comfort, less stress

People feel more comfortable walking and bicycling on streets with less traffic. Connecting traffic-calmed local streets can also offer important, low-stress routes for people to:

  • travel within their own neighborhoods
  • get to train stations or bus stops, or
  • to connect with the citywide bike network.

Buffered bike lanes

Buffered bike lanes provide more space between people on bikes and people in cars. The additional space can help prevent crashes that could be serious to those involved.

Reducing the risk of 'dooring'

Because it is placed along parked cars, the buffer gives bicyclists more room to avoid a “dooring”.  This happens when a driver or passenger opens a car door into the bike lane and hits a bicyclist.

Separated bike lanes

Separated bike lanes provide more space and vertical separation between people on bikes and people in cars. There are several ways to provide this physical separation.

Separated bike lane on Beacon Street
Location: Beacon Street, Back Bay

When we’re not reconstructing the street, we typically use flex posts. The posts indicate a separated bike lane. During the winter, we remove the posts so they don’t get damaged by winter maintenance activity.

Location: Columbus Ave, Roxbury

On streets with parking, we place the separated bike lane between parked cars and the curb. We call this a parking-protected bike lane. People on bikes should yield to those who are crossing the bike lane between the sidewalk and their vehicle. Unless otherwise signed, all parking rules remain in effect on these streets.

When we are reconstructing a street, we can build sidewalk-level separated bike lanes. These bike lanes are at the same height as the sidewalk. People should not walk along these lanes. But, they may cross them to access bus stops and parked cars or to cross the street. People riding bikes must yield to people walking across the bike lane. We can also build separated bike lanes with permanent curbs when reconstructing a street.

Separated Bike Lane on Atlantic Ave, North End
Location: Atlantic Ave, North End

Most often, separated bike lanes are one-way for people biking. People should bike in the same direction as car traffic. Less often, we build two-way separated bike lanes. Two-way separated bike lanes need more work to make sure intersections are safely designed.

Contraflow bike lanes

Contraflow bike lanes are a type of bike lane that allow people biking to go both ways on a street that is one-way for motor vehicles.

Direct Routes, Better Access

One-way streets help manage the traffic flow. But, we might want to allow people to bike in both directions on a one-way street if one or both conditions are met:

  • Using the one-way street in the contraflow direction helps bicyclists avoid an obstacle, like a major hill or busy street without a separated bike lane.
  • There is a major destination, park, or trail access point most easily accessed via the one-way street.

On streets with higher traffic volume and higher speeds, we can add contraflow bike lanes that are separated from vehicle traffic, just like separated bike lanes. This reduces conflicts and helps more people feel safe riding bikes. We design intersections to ensure drivers and bike riders can see each other.

On streets with lower traffic volume and lower speeds, we can add contraflow bike lanes with paint and signage. The lane is positioned so that bicyclists ride on the right side of the street in the direction they are traveling, just like on most two-way streets. If there is parking, the lane is painted along the passenger side of parked cars.

A reminder

For a safer Boston: Speed Limit 25 mph

As a reminder...

Bike lanes can be built in many different ways and go by many names. But, at the end of the day, they’re still lanes for bikes and no one should drive* in them. 

When driving, you should always check your mirrors. Remember to look back before changing lanes, turning, or opening your car door. When biking, avoid riding in vehicle blind spots and be sure to use lights at night. Whether driving or biking, always yield to people walking and be considerate of other road users.

*We make an exception for emergency responders and people who keep our bike lanes clean and clear of snow.
