text: While federal legislation designating the south Texas branches as I-69 suggested that these routes may be designated as "I-69E" (east, following US 77), "I-69C" (central, following US 281), and "I-69W" (west, following US 59), the American Association of State Highway and Transportation Officials Special Committee on Route Numbering rejected the Texas Department of Transportation's request for these three designations along the proposed I-69 branches, citing that AASHTO policy no longer allows Interstate Highways to be signed as suffixed routes.
