I-69 Statement of Purpose and Need

(From the Feb. 7, 2000 "I-69 Corridor 18 Special Environmental Study")

I-69 is and integral part of High Priority Corridor 18 across mid-America.  Corridor 18 originated with the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) where the U.S. Congress designated certain highway corridors of national significance to be included in the National Highway System.  The corridor now has been defined by Congress to extend from Port Huron, Michigan at the Canadian border.  Corridor 18 incorporates the following elements:

  • Existing I-69 from Port Huron, Michigan/Sarnia, Ontario, Canada to Indianapolis.
  • Existing I-94 from Port Huron through Detroit (including the Ambassador Bridge interchange) to Chicago, Illinois.
  • A new Interstate route (I-69) from Indianapolis to the Lower Rio Grande Valley (LRGV) serving the following:
    • Evansville, Indiana
    • Memphis, Tennessee
    • Shreveport/Bossier City, Louisiana
    • Houston, Texas
  • The Southeast Arkansas I-69 Connector from Pine Bluff, Arkansas to the I-69 Corridor identified in the Special Issues Study in the vicinity of Monticell, Arkansas.

  • In the Lower Rio Grande Valley:
    • US 77 from the Mexican border at Brownsville to US 59 in Victoria, Texas.
    • US 281 from the Mexican border at McAllen to I-37, then following US 59 to Victoria, Texas.
    • The Corpus Christi Northside Highway and Rail Corridor from the intersection of US 77 and I-37 to US 181.
  • FM 511 from US 77 to the Port of Brownsville
