Earth Day Celebrations and New I-35 Park Renderings

Austin, TX · April 22, 2026

Happy Wednesday—it’s Earth Day, and while the sky is offering a bit of a damp start, the city is leaning into the green today. Whether you’re heading to Waterloo Greenway for the festivities or just navigating the usual I-35 shuffle, keep an umbrella handy for that morning drizzle before things clear up this afternoon.

📰 The Lead

The long-discussed transformation of our downtown skyline took a more concrete shape yesterday as the city and TxDOT released the most detailed renderings yet for the I-35 "Cap and Stitch" project. These plans envision massive landscaped decks covering the lowered highway, specifically focusing on the stretch between 4th and 7th Streets.

The new designs move beyond simple grass patches, proposing integrated amphitheaters, community plazas, and a significant expansion of the city’s canopy with hundreds of new trees. For residents, this represents more than just a park; it’s a multi-million dollar attempt to physically bridge the divide between East Austin and the downtown core that has existed since the highway’s original construction. While the orange barrels aren't going anywhere soon, these visuals provide a much-needed glimpse of the finish line: a city that prioritizes walkable green space over concrete canyons.

📸 Spotlight & Story

  • The Ann and Roy Butler Hike-and-Bike Trail
    • While we often take it for granted as our daily exercise route, this 10-mile loop is truly the "Living Room of Austin." Born from a 1970s beautification project led by Lady Bird Johnson, the trail was a radical idea at the time—turning a neglected riverbank into a premier urban sanctuary. Today, it sees over 2.6 million visits a year. One sharp detail: the boardwalk portion near Riverside Drive features 2,100 pre-cast concrete planks, each designed to withstand the inevitable rise and fall of the Colorado River.
