(From the Feb. 7, 2000 "I-69 Corridor 18 Special Environmental Study")
Development of the proposed I-69 Corridor would provide a continuous highway link designed to Interstate highway standards from the Mexican border to the Canadian border, a route length of approximately 1,650 miles (2,650 km). I-69 currently exists to Interstate highway design standards from the Michigan/Canada border to the northeast side of Indianapolis, Indiana. Existing I-69 is in need of bridge and pavement maintenance and upgrades while it also has capacity deficiencies in certain locations. The extension of I-69 to the Texas/Mexico border would cover a route distance of about 1,250 miles (2,050 km).
There is no existing Interstate facility with Corridor 18 for the full distance from Indianapolis to the Texas/Mexico border. This missing Interstate link is in a corridor that has a high demand for NAFTA associated goods movements. However, short to medium length trips far outnumber international traffic along the corridor. There will be local and regional trips that will take advantage of an improved facility designed to Interstate highway standards. By diverting these local trips to the I-69 Corridor, the adjacent state and federal highways will likely see a drop in overall traffic levels with attendant increases in travel efficiency and motorist safety. Without this extension of I-69, travel on a facility designed to Interstate standards would be indirect between the named cities in the I-69 Corridor and from border to border.
Throughout its length, I-69 would connect 16 existing Interstate highways crossing Corridor 18 (10 east-west routes and 6 north-south routes). It would link 10 urban areas or more than 50,000 population along the corridor. Within urban areas, development of I-69 could provide the means to upgrade existing Interstate routes, connect major transportation corridors and radial freeways with a new facility, and connect modal and multi-modal terminals to the Interstate highway network.
