Segments being designed:
No segments currently under construction.
Segments open to traffic:
This branch of I-69 has been called "I-69 East" in some planning documents. The portion south of Odem may be signed as an extension of Interstate 37, or it may be assigned a new number or a spur designation. It is unlikely to receive an "I-69E" designation.
From Brownsville, this corridor follows the U.S. 77/83 freeway north to Harlingen, then follows U.S. 77 north to I-37 at Calallen, and continues along the U.S. 77 corridor to Victoria, where it joins the Laredo/McAllen branch.
According to this post to misc.transport.road, a number of interchange projects are underway or planned along U.S. 77 to upgrade bypasses of Lyman, Raymondville, and Sebastian to or near freeway standards.
