|SUBJECT:||Catwalks on VMS Sign Supports|
At the Maintenance Supervisors meeting in April, the issue of providing catwalks for VMS was raised. Based on the discussion at the meeting, the following guidelines should be followed.
8 Foot Shoulder (or more) is Provided
Provide a catwalk on the sign support.
Less than 8 foot Shoulder is Provided
Do not provide a catwalk on the sign support.
The Maintenance Supervisors advise that if the shoulder is less than 8 feet, a lane must be taken to perform maintenance on the VMS, and the catwalk does not facilitate the maintenance effort.
