Expanding I-35 is a
bad deal 
for Texans

20+ lanes wide • $5+ billion wasted • 8+ years of construction • 100+ bulldozed homes & businesses •  Worse traffic

Tell CTRMA - Don’t Expand Mopac South!

The Central Texas Regional Mobility Authority (CTRMA) is considering expanding Mopac South. This would flood Austin and the region with more traffic and pollution.

We’re fighting for smarter ways forward

Rethink35 is a grassroots movement fighting the planned I-35 expansion through Austin, Texas.

We are pushing for a study of alternatives, including rerouting non-local traffic and replacing the highway with a boulevard.

The state’s way is a highway

22 lanes, yikes

  • Demolishes over 100 homes, businesses, and schools

  • Increases road noise, pollution, and carbon emissions

  • Worsens congestion by encouraging more driving

We think cities are for people

  • New, affordable housing and local businesses

  • Wide sidewalks, protected bike lanes, more transit

  • Non-local traffic can travel around town, not through it

We stand WITH dozens of businesses, organizations, and elected leaders.

“I cannot support [I-35 expansion]... Wider highways don't work.”

- Greg Casar, U.S. Congressman

“This project is completely out of step with the will of the public.”

- Paige Ellis, Austin Council Member

“Why are we expanding I-35? We should be investing in transit.”

- Gina Hinojosa, Texas State Rep.

Wait, but…?

There’s some misinformation out there about traffic congestion and the I-35 expansion plan — we’ve got the facts.
