Statement Regarding Oversized Vehicles


Due to ongoing construction throughout the City, to include the port areas, any oversized load requiring the use of escort vehicles must contact the Road Compliance Department seven (7) days prior to the move date so the necessary arrangement may be made.


Failing to do do may result in the load getting turned away.
