Routing Help


The goal of the routing page is to use one of the methods provided to select the route to be used by the permit vehicle and ask the system to check whether or not the route can be permitted.  The route analysis process will typically check the continuity of the route, all horizontal and vertical clearances along the route, all temporary restrictions (construction or otherwise) in effect during the extent of the permit, and for overweight vehicles, perform an actual live load analysis of every structure the permit vehicle will cross over.

You can select the option to "Request office review" at any time if you encounter any problems you do not understand or are unable to successfully route your vehicle.  However, if you are able to successfully route the vehicle, you should select the default option to "Use selected trip to request permit".  You may be able to have the system issue the permit without any permit office intervention (in specific cases controlled by the permit office), or the analysis you have performed will help the permit office process your permit more quickly in the cases where the permit office requires it to be reviewed.



There are two basic types of commands available on the routing page.  They are commands for Map Navigation and Query and commands that actually perform the Routing.  Following is more detail on each specific command for each of the two groups.

Map Navigation and Query

There is a map zoom control in the top left corner of the map. Use the arrows to pan (scroll) the map. Click the circle between the arrows to fit the map to the window. Use the slider to change the zoom level. And use the magnifying glass to enable the zoom in command so you can zoom to a point you pick on the map or draw a window on the map that you want to zoom. You can also use the mouse scroll wheel to zoom in and out about the location of the cursor. The mouse can be panned (scrolled) by dragging the map. Hold the left mouse button down and drag the map as you want to dynamically pan the map. It should be noted that most of the routing commands automatically do map manipulation based on where they believe the trip is going.

Several commands are provided to change the information shown on the map, as well as to find and highlight specific elements. These commands are found on the border of the map. The commands are provided to help better use the map for routing purposes. Following is a list of the commands along with a basic description of how they work.


There are five possible methods for routing the vehicle are provided.  There may be some variation in routing options enabled in a specific implementation.  The options include Picking Route Segments, Text Description, Auto Orig/Dest Routing, Loading Saved Trips, and Manual (Free form text).  The various methods have been provided to give you options in defining trips in the way you are most comfortable.  The following sections describe how and why to use each option.  Each routing option provides the ability to request a permit office review at any time.  Depending on the type of permit and the rules currently in place with the permit office, you may also be able to automatically receive a permit for a vehicle you successfully route through this page without requiring any interaction or specific approval from the permit office.  At the conclusion of any analysis, the results of the analysis will be summarized in a small form and the trip will be color coded showing passing and failing areas. 

There are two other options related to routing that let you Clear the current trip and start over, and Save trip for future use to speed the route selection of frequently used routes.  Additionally, there are two Advanced Options that are available when using the picking route segments method.  These advanced options allow you to Remove the last trip segments from the end of the trip you are currently selecting, and Add additional trips to the route request.  Both of these Advanced Options will be described below.

Clearance Analysis Override

If you can certify that the route entered into the system can be safely traversed by a vehicle having the height and width dimensions that you entered into the permit application, you may choose to use the “Clearance Analysis Override” option by clicking the Clearance Analysis Override checkbox in the left margin of this page.  If you cannot certify that the route entered into the system can be safely traversed by a vehicle with the height and width dimensions entered into the permit application, then do not check the Clearance Analysis Override checkbox, as this may put yourself or the traveling public in harms way.  Selecting this option may result in, but does not guarantee, getting a permit issued more quickly as other restrictions may apply.
