Roadway narrowing

Roadway narrowing can be achieved in two different ways. The lane width can be reduced, with excess asphalt then striped with a bicycle lane or paved shoulders. These treatments make the driving area appear to be narrow without adding curbing to physically narrow the roadway.

The street can also be physically narrowed by extending sidewalks, providing landscaped areas, or adding on-street parking within the former curb lines. This often reduces vehicle speeds along a roadway section and enhances movement and safety for pedestrians.

Adding bicycle lanes on higher-volume streets with speeds in excess of 20 mph enhances bicycle travel by increasing the predictability of both car and bicycle movements. Such treatments are particularly desirable for a neighborhood when several streets are treated in this way to create a connected system of bike lanes.

Used for

  • Reducing speeds, increasing safety and redistributing space to other users and uses.
