Designed with alternating elements that create an "S" curve in the roadway, chicanes make drivers "weave" down the street at slower speeds. They can be created by alternating curb extensions, planters, and/or on-street parking that switches from one side to the other along several blocks.

Benefitschicanes example

  • Slows driving speeds through visual, permanent cues
  • Maintains access
  • May provide additional opportunities for landscaping, if appropriate maintenance agreements can be put in place


  • Chicanes may not be used on roads with more than two lanes
  • May impact drainage
  • May change the number of parking spaces
  • Chicane design should consider street cleaning and snow removal operations
  • Must be clearly marked to alert operators of the change in the roadway
