In 1971, Friendship Park was established along the US-Mexico border as a binational meeting place—a rare space where friends and families separated by immigration policies could reunite, share moments, and bridge the divide through human connection, albeit through the separation of a fence. Situated on the shared shoreline of San Diego and Tijuana, the park embodied the spirit of cross-border unity. However, in 2009, the construction of a secondary border fence drastically restricted access, reducing the park to a mere shadow of its original purpose.
La Línea Borrosa seeks to restore this lost connection by creating a new binational gathering place—one where people can meet freely, without the separation of a fence. The name itself holds a dual meaning in Spanish: it translates to both “the blurred line” and “the blurred border”—symbolizing a space where the rigid political boundary softens, and human connection takes precedence over division.
The project consists of four key elements:
A new pedestrian border crossing
The Spiral Pier, a floating public space in neutral waters
The Americas Gateway Bridge, a suspension bridge reconnecting both sides of the border
A new trolley line, linking this crossing to San Ysidro and beyond
Currently, crossing the border at San Ysidro—the busiest land border crossing in the world—is far from a pleasant experience. Pedestrians wait in long lines next to a sea of idling cars, surrounded by noise, exhaust fumes, and the chaotic congestion of vehicular traffic. La Línea Borrosa introduces a new pedestrian border crossing that removes people from this harsh environment, providing a dignified, human-centered alternative.
This crossing, integrated into the Spiral Pier and the Americas Gateway Bridge, allows visitors to move freely between nations in an environment designed for people, not cars. The transition between countries becomes a contemplative, communal experience, set against the backdrop of the Pacific Ocean rather than the gridlock of a highway checkpoint.
Extending into the Pacific just beyond where the border fence vanishes into the waves, The Spiral Pier is a hybrid of wood and concrete, designed as a legal gray zone, existing beyond the jurisdiction of either the United States or Mexico. Here, visitors could meet without fear of deportation, in a place that neither nation claims as its own—an unclaimed space for shared humanity.
The pier is accessible by trolley, pedestrian bridges, and the Americas Gateway Bridge. A spiraling ramp winds around its structure, creating an unconventional promenade with gathering spaces, where families and friends can reunite in pre-reserved areas. Before visits, guests could send photos, which would be displayed on a large welcoming screen at the border crossing, reinforcing the personal connections that the structure exists to support.
Anchored in the Spiral Pier, the Americas Gateway Bridge is a suspension bridge spanning the border, reconnecting San Diego and Tijuana through a human-centered crossing. The bridge features two soaring pylons—one on each side of the border, serving both structural and symbolic roles.
The north pylon, located on the U.S. side at the Spiral Pier, features an elevated viewing deck, offering visitors a new aerial perspective of the border region. From this vantage point, one can look back at the line dividing the two nations, reflecting on the contrast between restriction and movement, separation and connection.
As the bridge extends southward into Mexico, it wraps around Plaza Monumental de Tijuana, the city’s historic 21,000-seat bullring, an enduring symbol of Mexico’s rich cultural traditions. This integration turns the bridge into more than just a crossing—it becomes an immersive experience, where pedestrians can glimpse into the energy of the arena, blending movement and spectacle in a way that weaves together the narratives of both nations.
At its core, the Americas Gateway Bridge is not just about spanning a physical divide—it is about reimagining how people experience the border itself.
More than infrastructure, La Línea Borrosa is an act of resistance against division—a space removed from political bias, built for people rather than policies. The Spiral Pier offers visitors an opportunity to reflect on immigration policies and the human impact of borders, while the bridge and promenade invite them to experience connection in ways that defy physical and political separation.
By creating a place where movement is free and encounters are unrestricted, La Línea Borrosa asks us to reimagine what a border can be—not a barrier, but a meeting place—one where the histories, traditions, and cultures of two nations are interwoven into a single, shared experience.
