An 11-mile corridor through Dallas, TX — where a $666 million highway rebuild became a statement about geology, community, and the power of textured concrete.
The TxDOT I-35 Southern Gateway project reconstructed one of Dallas's most critical interchanges — an 11-mile, $666 million design-build effort widening I-35E south of downtown and rebuilding the I-35E/US 67 interchange. Spec Formliners supplied two distinct custom urethane liner products: MSE liners for GeoQuest's precast retaining wall panels, and noise wall liners for Pegasus Link Constructors' cast-in-place walls throughout the corridor. Both products share the same "Strata" texture — drawn directly from the stratified rock escarpments of Oak Cliff — creating a unified architectural identity across the full 11 miles regardless of pour sequence or panel supplier.
The design carries real weight. I-35E was originally built through Oak Cliff in the 1950s, displacing a thriving Black community. This reconstruction — including the Halperin Park deck park opening Spring 2026 — is a generational act of reconnection. The strata texture ties the parkscape above to the concrete below, letting the walls reflect the geology and culture of the neighborhood they pass through.
Whether it's a DOT sound wall, an MSE retaining system, or a community landmark — we engineer the formliner to match your vision.
