Neighborhood Traffic Management Program (NTMP)

Tools to Address Speeding and Traffic Volumes

Full Closures/Cul-De-Sacs

Top view of a street with full closures
  • Full closures or Cul-de-Sacs close one end of a street.
  • They are used to force changes in travel patterns - such as preventing cut-through traffic in residential neighborhoods or to eliminate dangerous or problematic intersections.
  • Care should be taken to consult neighborhoods when proposing cul-de-sacs or full closures because access to properties may become more difficult resulting in potential delays for residents.
  • Sidewalks can be left open.
