On-System Project Funding

The entire On-System project funding is approved up to the most reasonable termination point for approach work, not to exceed 400-ft average approach roadway length (800-ft total approach length). Items not eligible for federal funding are excluded and must be funded by another funding source.
If the project limits exceed the allowable length of approach road, as described above, then the following equation (% RD/BRG) is used to determine the maximum allowable Category 6 funds for projects up 15 million dollars.
  • {% Road/Bridge Equation}: {[(Bridge Costs) x 1.25] + (Mobilization + SW3P + Traffic Handling and Barricades + Removal of the Old Structure + Approach Rail + Bridge Approach Slabs)}.
  • Costs are limited to no more than 25 % Road/Bridge, and not greater than 2 times the cost of the Bridge Items.
All On-system Projects over 15 million dollars will be evaluated on a case-by-case basis to determine the amount of Category 6 funds available, as well as any additional funding that is required to cover the funding gap.
For On-system Project, if both statements below are true, it is recommended to add an additional category of funding showing one dollar in TxDOT Connect. This will allow for easy identification of Category 6 projects that may be at risk of having a funding gap.
  • Total initial estimate of the project is more than two time the bridge cost.
  • The project has more than 800 feet of approach roadway work.
