FULL
CLOSURES/CUL-DE-SACS
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.
