 (TxDOT) originally considered building the I-69/TTC over new terrain paralleling US-59, US-77, and US-281.

Responding to widespread opposition from environmental groups and property rights activists, TxDOT announced in June 2008 that it will complete I-69 by upgrading the existing US-59, US-77, and US-281 roadways to Interstate standards through rural areas, with bypasses around urban centers along the route. Instead of building the Trans-Texas Corridor as originally planned, TxDOT now plans to finance upgrading the existing highways to I-69 through private sector investment. Under the proposed arrangement, I-69 would remain toll-free where it overlaps pre-existing highways, while bypasses of cities may be tolled. The private firms awarded contracts for I-69 would also build and operate toll roads throughout the state; some of those revenues would then be applied to I-69 construction.

A stated goal of TxDOT's I-69 initiative is that "existing suitable freeway sections of the proposed system be designated as I-69 as soon as possible." In response to TxDOT's request, a six-mile segment of US 77 between I-37
