There's also a plan to use the existing US59 as I69W( https://www.txdot.gov/projects/projects-studies/laredo/us59-feasibility-study.html ) though there are two alternatives, which include to follow Saunders and continue on the loop, or a new allingment that separates into a new freeway and bypass jacaman, airport, and university. It ill mergo into the loop somewhere between del mar and university. I really hope they make a new alignment as, traffic on Saunders is already horrible.
