Project Selection

The commission approves projects selected for this category. Projects are selected using a statewide prioritization process that utilizes a calculated score for each candidate bridge project. The score considers average daily traffic, cost per vehicle, bridge condition, adequacy of roadway width, and overall bridge sufficiency. The actual scoring process is referred to as the Texas Eligible Bridge Selection System (TEBSS). However, projects involving eligible candidate bridges that are appraised by TxDOT as having a “critical condition” may be selected regardless of the TEBSS score.

For off-state system projects selected under the statewide prioritization process, consideration may be given under certain circumstances to a local government’s preference to fund a substitution project. TxDOT staff will consider the justification of each proposed substitution on a case-by-case basis and prepare specific minute orders for commission action as appropriate.
