Klyde Warren Park
Dallas built a 5.2-acre public park on a structural deck spanning the Woodall Rodgers Freeway.
Relevance to Gold Star Green
Shows that a highway cap park - a structural roof over heavy infrastructure - can be delivered by a public-private partnership in which the city, state DOT, and private funders each carry a distinct share.

Klyde Warren Park
What it is
Klyde Warren Park is a 5.2-acre public park in downtown Dallas, bridging the recessed Woodall Rodgers Freeway (Spur 366) between Pearl Street and St. Paul Street and reconnecting the Arts District on the south side to the Uptown neighborhood on the north side. The park opened on October 27, 2012. It is owned by the City of Dallas, built on Texas Department of Transportation (TxDOT) highway right-of-way, and operated on a long-term basis by the Woodall Rodgers Park Foundation, a private civic foundation. Programming includes a performance pavilion, food trucks, a dog park, a children’s area, a restaurant, reading room, and event lawns.
What was there before
Before the park, the site was an approximately five-block stretch of the Woodall Rodgers Freeway, an eight-lane below-grade expressway completed in the 1980s that cut through downtown and separated the Dallas Arts District from Uptown. The freeway remained in active use; it was not abandoned or decommissioned. The gap above the freeway was a structural and pedestrian void - noisy, exposed, and effectively unwalkable as a public space - which is why it was identified as a candidate for a deck park rather than for at-grade redevelopment.
The engineering move
The core engineering move was to construct a structural deck over the operating freeway and then build a real park, with soil, trees, water features, and buildings, on top of it. The deck is supported on new columns and beams placed in the freeway median and shoulders, with the existing highway lanes continuing to operate underneath throughout construction and after completion.
Three constraints shaped the structural design. First, the highway below had to remain open, so construction sequencing used lane closures and girder lifts rather than a full closure of the corridor. Second, the deck had to support not only pedestrian loads and hardscape but planting soil deep enough for mature trees, along with the weight of the park’s buildings and water features; lightweight structural fill and engineered soil volumes were used where possible to manage dead load. Third, the deck design had to handle ventilation, exhaust management, drainage, and fire life-safety for the tunnel-like space it created beneath. Dallas’s design team delivered a deck that treats the freeway below as permanent infrastructure and the park above as a second, independent program - stacked, not merged.
What it cost
Klyde Warren Park’s construction cost is widely reported at approximately 110 million US dollars for the initial build-out completed in 2012, with a subsequent expansion and improvements adding further cost later in the decade. The funding stack is the part most directly relevant to Gold Star Green: it combined City of Dallas bond funds, federal stimulus (ARRA) dollars channeled via TxDOT, TxDOT highway funds, and private contributions raised by the Woodall Rodgers Park Foundation, including a naming contribution from the Warren family. Dollar figures cited downstream should be annotated as approximately 110 million in 2012 dollars for the initial park. Figures are reported by project publications and press coverage; primary-source verification against audited City of Dallas capital project documentation and TxDOT project records is pending as of 2026-04-13 and an editor should confirm before publication.
Why it matters for Gold Star Green
Klyde Warren Park is the precedent that most closely matches Gold Star Green’s intended governance and funding shape. The park is owned by a city, built on another jurisdiction’s right-of-way, and operated by a private civic foundation; the capital stack splits city bonds, state/federal infrastructure dollars, and private contributions; and the thing underneath - a live highway - is neither removed nor rebuilt in order to get the park delivered. The park simply sits on top of the highway. That is the same move Gold Star Green is proposing in Cambridge: whatever happens on April 15 with respect to the soil and the excavation, the coalition builds the roof.
Klyde Warren also shows a realistic scale. At 5.2 acres and roughly 110 million 2012 dollars for the initial build-out, it is closer in magnitude to a deliverable Cambridge project than Millennium Park’s 24.5 acres and 475 million 2004 dollars. This section does not predict that Gold Star Green will match Klyde Warren’s budget, timeline, or programming. It only observes that Klyde Warren is a working, operating example of a public-private coalition building a structural park-roof at a scale a mid-sized city can plausibly absorb.
