There are three principal types of passes constructed and maintained by TxDOT:

the stock pass, usually used to permit livestock to cross under the traveled lanes of traffic;
the vehicular pass, sometimes needed to permit trucks, farm machinery, etc., to cross a controlled access highway; and
the pedestrian pass, needed over an access-controlled highway such as the Interstate System.

The Commission policy for passes on controlled access highways is 43 TAC 21.81.

If the transportation project will create large severance damages by splitting the owner’s land, Design Division should be consulted for possible design changes to create a pass, thereby reducing right of way costs.

Assumption of pass facilities should be offered to the landowner

before

any appraisal of the property.

Prior to appraisal, various division and district offices (Construction, Design, and Maintenance Divisions) will provide appraiser instructions regarding passes on a project.
