The LTRC Foundation is governed by a board of directors whose composition reflects the nature of the transportation community (public, private, and academic). Included in this group are three representatives of DOTD, two LTRC administrative positions, four private industry representatives, and representatives of the seven Louisiana universities with engineering programs (University of New Orleans, Southern University, University of Louisiana at Lafayette, Louisiana Tech University, McNeese State University, Tulane University, and Louisiana State University).

The LTRC Foundation: The foundation was chartered as a non-profit corporation instituted solely for the purpose of enhancing and supporting LTRC. A primary purpose of LTRC is to establish cooperation among the groups who work to improve Louisiana’s transportation systems. The LTRC Foundation represents a unique opportunity for government, industry, and academia to partner in meeting that expectation.

Accomplishments: The foundation exists to enhance and support LTRC as the focus for 1) transportation and safety infrastructure research, 2) education, and 3) transportation training in Louisiana. The first goal of the foundation was to plan, develop, and construct the Transportation Training and Education Center (TTEC) for the entire transportation community. This goal was realized when TTEC became operational in January 2006.

Other accomplishments include the ALF (Accelerated Loading Facility) Building and addition of the ATLaS 30, which maximizes pavement testing by simulating the effects of dual truck tires at maximum loads over various distances on both asphalt and concrete pavements. In addition, the foundation has led the distribution of AASHTO scholarships and awards to local students, impacting the next generation of leadership in the transportation community.

Future Goals: While the foundation is proud of its accomplishments, much work remains in the quest to lead LTRC to national prominence. Future goals for the LTRC Foundation include:

  • Planning and construction of a new LTRC building
  • Enhancing the research/equipment capabilities of LTRC
  • Endowing LTRC Research Professorships
  • Promoting TTEC as a regional center for transportation workforce development

Supporting the LTRC Foundation: The LTRC Foundation seeks to effect a true public/private partnership for improving transportation in Louisiana. In that regard, parties interested in supporting the foundation are encouraged to contact the LTRC Director or any member of the LTRC Foundation Board of Directors for further information.

Tax Exempt status of foundation: The LTRC Foundation was incorporated as a non-profit corporation under Section 501(c)(3) of the Internal Revenue Code and has been assigned an Employer Identifi cation Number, 72-1350383. Tax exempt status was approved by the IRS on April 10, 1998. Accordingly, donors may deduct contributions to the foundation as provided in Section 170 of the Code.
