This help document refers to the Texas Load Zone application.
This application is a graphical representation of pavement load limit data.
Please note that this application comes with some limitations. The data for
the application is taken to be suitable for planning and general mapping
purposes. The base map data is hosted by Microsoft, independent of TxDOT,
so TxDOT has no control as to the content or accuracy of the data. This
application was developed and is maintained by the Technology Services Division
(TSD).

measurement tool is enabled, other features such as querying and identifying features will
be disabled. Pan or zoom in to the location where you want to measure distances. Click on
the map two or more times, and the measurement tool will update the distance between each leg,
along with a total distance from the first to the last click. To clear and restart measuring,
click on the Clear Measurement button. To exit and disable the measurement tool, click on the
X in the top right corner of the measurement tool window.

Clicking on the plus icon next to the district will expand and list the counties
for that district. Clicking on either the district name or the county name will
filter the roads for that district/county. The filtered roads will display in the
results pane. Additionally, the map frame will zoom in to the selected district
or county extent.

The results pane displays an interactive table of results when
either the district or county name is used to filter results. The data can be
sorted in ascending or descending order by clicking on each of the column names.
Clicking on a row will cause the map frame to zoom in to the extent of the
selected road, highlighting it in yellow.
