ROFL. That money was already allocated as part of Texas' share of federal highway funds. Paul has no control over how Texas applies it. Get back to me if he specifically earmarked the money for the TTC.
Glad to, he earmarked it for the specific purpose of the I69TTC project, feasibility studies of the TTC. Not for a 'general highway fund'

I69 doesn't fall into existing maintenance because it is part of the new TTC highway system.
