Diagonal diverters place a barrier diagonally across an
intersection, disconnecting the legs of the intersection.
Strategically located diagonal diverters
reduce traffic volumes on a street. Diagonal diverters prevent through
moves at an intersection.
|Effectively reduce traffic volumes
Can restrict vehicle access while retaining bicycle and
Prohibit or limit access and movement. While this is the
purpose of diversion devices, some drivers consider it a disadvantage.
Restrict access for emergency and transit
Diagonal diverters cost approximately $15,000 - 35,000.
Transit Service Impacts:
Diagonal diverters should not be considered on transit
Emergency Services Impacts:
Generally, the turn restrictions imposed by a diagonal diverter
would apply to emergency vehicles as well and are typically not used on primary
fire response routes. However, diagonal diverters can be designed and installed
to provide for emergency vehicle access.
Diagonal diverters apply to all drivers, including local
residents. Very special care must be taken to consider the availability,
capacity, and appropriateness of the alternative routes drivers might use if a
diverter is constructed.
Provision should be made to make diverters passable for
pedestrians and bicyclists.
