  1. Review of Rural Highway Traffic CountsCan the Trans-Texas Corridor be Justified? By Erik Slotboom Toll & Corridor Summit Meeting November 13, 2004

  3. Trans-Texas Corridor Overall Conclusions • Only one corridor may justify a relief route:I-35, San Antonio to Hillsboro • Existing Interstates are adequate in all other cases • Some sections of existing Interstates will need a 3rd lane in each direction by 2034 • Trans-Texas corridor cannot be justified

  4. How much traffic can existing Interstates handle? Approximate

  5. Typical 4-lane Rural Interstate Interstate 35W South of Fort Worth

  6. Typical 4 lane InterstateHow much traffic can it carry? • A 4-lane freeway can serve > 100,000 vehicles/daywith reduced service

  7. Typical 6-lane Interstate I-35 North of New Braunfels

  8. Typical 6 lane InterstateHow much traffic can it carry? • A 6-lane freeway can serve > 200,000 vehicles/daywith reduced service

  9. Implied Tran-Texas Corridor Traffic

  10. What kind of traffic counts do we have in 2003? Is it anywhere approaching Trans-Texas capacity?

  11. 2003 traffic data Source: TxDOT

  12. Existing traffic volumes are easily handled by existing 4-lane InterstatesWill traffic grow to Trans-Texas proportions?

  13. Interstate 10Houston to San Antonio 2003 Traffic Data

  14. Interstate 45Houston to Dallas 2003 traffic data

  15. Interstate 35San Antonio to Laredo“NAFTA Corridor” • There has not been a NAFTA traffic boom • Traffic counts stagnant since 2000 2003 traffic data

  16. Strong growth in 1990s • Stagnant since 1999 • Traffic Count still very low NAFTA Influence

  17. Interstate 69 Corridor • Can it justify a Trans-Texas corridor? NO. A conventional 4-lane interstate will serve traffic needs 6-lane sections needed approaching Houston

  18. 2003 traffic data

  19. Interstate 35San Antonio to Hillsboro • The only corridor that could possibly justify something resembling a Trans-Texas corridor • Original TxDOT plan:widen existing facility to 6 (rural) and 8 (urban) lanes

  20. I-35 2004 Status • 4-lane sections south of Hillsboro need added lane in each direction immediately • Expansion on hold pending Trans-Texas plan 2003 traffic data

  21. Financial Case Study • What if we build a Trans Texas Corridor from Georgetown to Hillsboro?This is the only corridor section that has a remote chance of being viable

  22. How Much Would It Cost? Compare to SH 130, Austin to Georgetown: 6 lanes, 102 miles Assume a minimal Trans-Texas corridor, 4 highway lanes only but on a wide corridor

  23. How Much Traffic Will Use It? Compare to Hardy Toll Road / I-45 Corridor in Houston to determine I-35 / Trans-Texas split • Interstate 45 north in Houston is one of the most heavily loaded freeways in the United States (per lane-mile)

  24. Conclusion • Toll road traffic has been consistent at 15% of corridor traffic in spite of severe congestion on I-45 • Motorists will endure severe congestion to avoid tolls

  25. Analysis Assumption • Toll percent of corridor traffic stays low until I-35 is severely congested

  26. Other Assumptions • No capacity improvements to I-35;4-lane sections remain 4 lanes forever • $10 toll Georgetown-Hillsboro ($.09/mile)increasing at 3% per year • 10% corridor traffic increase after 20 years due to induced demand • Assume 4.5% interest, 40 year term on $2.75 billion in bonds. Annual Payment: $149 million

  27. Financial Shortfall • About 25 years of subsidy required Where will the money come from?

  28. Toll Interstate 35!

  29. Conclusion • Tolling existing rural interstates is the only way to make any Trans-Texas corridor viable • Bribe rural counties with a cut of the money to defuse rural opposition

  30. Other Financial Risks • High gasoline cost – lower traffic counts • Faulty assumptions (eg NAFTA) • Lower than forecast population growth • Predominantly Hispanic population • Hispanic regions most anti-toll • Lower income groups can’t afford tolls

  31. Slower Population Growth? Dallas Morning News, October 4, 2004

  32. NAFTA: what happened? 1990s assumption: future traffic boom 2000s reality: Everything is being made in China Result: Flat traffic volume to Mexico

  33. Alameda Corridor in Los AngelesPaying the Price for Faulty Assumptions • $2.5 billion spent on rail lineNow it is grossly underutilized “In the nearly two decades it took to plan and build the corridor, the shipping business changed so dramatically that the economic assumptions underpinning the project became obsolete.” L.A. Times, August 22, 2004

  34. A Better Way to Meet Our Needs • Add extra lanes to existing interstates as needed • Rebuilding a 4-lane interstate to a 6-lane interstate costs about $10 million per mile, half the cost of a Trans-Texas corridor

  35. Actual needs in the next 30 years Can be doneWITHOUT TOLLS

  36. The Engineer Says Traffic counts can’t even remotely justify Trans-Texas Corridor The Financial Analyst Says Tolling will only pay a tiny fraction of the cost for decades The Concerned Texan Worries about steep tolls on existing Interstates to pay for it

  37. Trans-Texas Corridor
