Mid-Block Narrowing

Usage: Wide

Two curb extensions that create a pinch point. A mid-block narrowing (also referred to as a “hug”) physically or visually constricts the roadway, thereby slowing vehicular traffic or alerting drivers to the presence of a mid-block crosswalk. The curb extensions themselves can be of any variety, for example with plantings or other functional elements. A mid-block narrowing is equivalent to a gateway located mid-block. Review Gateway

Permanent mid-block narrowing: 97th Street, Queens

Benefits

Provides safety and traffic calming benefits as described in Curb Extension
Calms mid-block traffic speeds, particularly when vertical elements (e.g., bollards, trees, bike parking, etc.) are included in curb extensions
Enhances drivers’ awareness of presence of crosswalk at mid-block crossing
Provides space for greening, community facilities, bike parking, and/or stormwater source control measures

Considerations

  • At mid-block crossings on two-way streets, it is generally preferable to include a raised median or pedestrian safety island rather than or in addition to a mid-block narrowing, when space allows. Review Raised Median and Pedestrian Safety Island 

Application

Review application guidance for Curb Extension

  • Local streets with demonstrated speeding issues and/or a mid-block crossing

Design

Review design guidance for Curb Extension

  • Reduce lane width at mid-block narrowing to impact vehicle speeds; on low-traffic residential streets, mid-block narrowing can be combined with other design treatments, including Raised Crosswalks, Raised Speed Reducers, or vertical elements for maximum effectiveness
  • Locate trees and/or plantings within curb extensions of mid-block narrowing where appropriate. Review Tree Beds and Sidewalk Plantings in the Landscape Chapter
