The abortion filibuster prevented the state Senate from taking a last-minute vote on a proposed constitutional amendment that would have diverted about $900 million a year in oil and gas tax revenues.
That money now goes into the state rainy day fund. The constitutional amendment would have allocated that money for highway construction and maintenance.
But analyst Jay Crossley with the public policy group Houston Tomorrow questions whether the funding proposal would actually take care of the state's transportation needs.
"The Houston region, we are spending more per capita on automobile infrastructure than any other major region in the nation. And I don't think we're getting benefit from doing that."
Crossley says other modes of transportation suffer.
"We don't have meaningful walking and biking infrastructure, we don't have high-speed rail or really good connections between our major cities."
Gov. Perry has now called another special session for July 1. If legislators approve the proposed amendment, it would have to go to the voters to become law.
TxDOT has said it needs an additional $4 billion dollars to pay for future projects.
