Partial Street Closure:
|
|
A partial street closure uses a semi-diverter to physically close or block
one direction of motor vehicle travel into or out of an intersection;
it could also involve blocking one direction of a two-way street. Partial
street closures at the entrance to a neighborhood or area should consider
the traffic flow pattern of the surrounding streets as well. The design
of this measure should allow for easy access by bicyclists and all pedestrians.
A partial closure provides better emergency access than a full closure.
Since this design also allows motorists to easily violate the prohibitions,
police enforcement may be required. If the partial closure only eliminates
an entrance to a street, a turnaround is not needed; closing an exit
will generally require a turnaround.
• Prevent turns from an arterial street onto a residential street.
• Reduce cut-through traffic.
• Restrict access to a street without creating one-way streets. |

• Do not adversely affect access by service vehicles.
• Analyze whether less restrictive measures would work.
• Analyze whether other local streets will be adversely affected and/or
access into or out of the neighborhood would not be adequate.
• Will create out-of-the-way travel for residents and put additional traffic
on other streets.
• Consider impact on school bus routes, emergency access, and trash pickup.
• Will not solve speeding issues; speeds may increase on the new one-way
street. |

| A well-designed, landscaped partial street closure at an intersection typically
costs approximately $10,000 to $25,000. They can be installed for less if there
are no major drainage issues and landscaping is minimal. |
