I-35 Expansion in San Antonio

(1/2) > >>

With much less controversy than in Austin, TxDOT is undertaking a massive expansion of I-35 in San Antonio. They're double decking 10 miles of it northeast of I-410 with 3 non-tolled express lanes in each direction. The groundbreaking ceremony was held today and construction on the $1.5 billion project will last until 2027.



Combined with the widening of Loop 1604 from 4 lanes to 10, San Antonio is really going agro on its traffic problems.

It does beg the question though of why they can't do this for I-45 in Houston

Plutonic Panda:
Is this considered “double decking?” To me they’re just adding elevated express lanes. Double decking would technically be placing a deck over the existing highway.

Either way this is an excellent project. I wish they’d do this on US-101 from downtown LA to Topanga Canyon.

Aren't the elevated structures going to be "a deck over the existing" frontage roads?
