Bridges and Walls: The Complete Set

Written by

In early 2018, DnA aired a series of stories called Bridges and Walls . The topic was connection and division in California, both social and physical. The impetus for the series was then-candidate Donald Trump’s repeated calls for building a border wall on the US-Mexico border.

Amidst his language of division, DnA decided to explore the social and environmental impacts of several large infrastructure projects underway in California: among them, a contested high speed rail network; a wildlife crossing over an 8-lane freeway; a retrofit of the LA River that promises both benefits and challenges to the poor communities it runs through; and a planned continuation of a freeway.

We found that a bridge for some people can be a wall to others.

Freeways link communities while splitting others; a  bullet train connects tech workers north and south but severs a farming region; low-income Angelenos who’ve long lived in the shadow of a barren LA River now fear the “green gentrification” that is coming with a beautified flood control channel.

T he dividing line at the US-Mexico border also serves as a point of contact for families, artists and communities residing in its shadow.

In Bridges and Walls we explored these competing impulses, through  29-minute stories with ambient sound, music and interviews with residents, designers, builders, politicians, farmers, historians, critics.

Bridges and Walls also looked at invisible walls like zoning, gang borders and the Orthodox Jewish eruv; and bridges that are literally buried out of sight: the undersea cables connecting Southern California to the Pacific Rim via the internet that creates openness to the world as well as closed virtual communities. 

And we looked at connections that might exist in the future like ferry services on our ‘fourth border’ — the ocean — giving commuters on the coastline alternatives to the Pacific Coast Highway and the 405.

The series was supported by the California Arts Council and NPR’s Story Lab. It won the LA Press Club's 2019 Award for Investigative Reporting. Read our conclusions and catch all the episodes below.

Bridges and Walls: What We Found

To the extent connective themes emerged, one was that California’s infrastructure is at a point of change and tension between a 20th century vision of urban development — car-based, zoned by use, served by large, single-purpose, fixed infrastructure (freeways, the flood control channel) — and today’s more holistic approach.

This envisions mixed-use development alongside mass transit, a river that does more than simply channel rainwater into the sea, freeways that interconnect with other forms of mobility, even a huge bridge… for wildlife.

We also learned that Californians are both open and closed; receptive to change and deeply fearful of it; ambitious for infrastructure and anxious about its costs. Sometimes present anxieties seem to trump the long view, as with the high speed rail, which has met with so many challenges that the political will to complete it is diminishing. This raises the question of whether Californians recognize their state’s global importance.

1) Bridges and Walls: The Border Wall

Can a wall also act as a bridge? The U.S.-Mexico border wall stretches along 700 miles. It divides two nations that are strategic allies and trading partners, and continues to divide Americans along partisan lines. It also “brings people together in really remarkable and interesting ways,” says architecture professor Ronald Rael, and DnA tells their stories.

2) Bridges and Walls: High Speed Rail

California’s biggest infrastructure project is a high-speed rail network that would connect San Francisco, the Central Valley and Los Angeles, bridging communities cut off by the state’s difficult geography. However, farmers see the train as driving a wall through their land. Despite widespread criticism, parts of the route are being built in Fresno, opening up new opportunities in the Central Valley. This episode also explored why the press and public gets excited about the Hyperloop, still an imaginary form of super-speed transit, but is downbeat about high speed rail, a real project.

3) Bridges and Walls: Wildlife Crossing

Wild animals need to roam, but our freeways are in the way. Now a proposed bridge over the 101 would allow mountain lions and other wildlife to cross safely over the freeway and improve their access to food and mates. But can humans and predatory animals coexist in the city? And why did it take the “Brad Pitt” of mountain lions to make this bridge possible?

4) Bridges and Walls: LA River, part 1

Eighty years ago , rain poured down on Los Angeles. Floods washed out roads, bridges and thousands of homes. The devastation led to total channelization that would forever shape — and divide — Los Angeles. Now efforts are underway to build new bridges, bring back wildlife and forge new connections at the LA River. But with those efforts come anxiety about change, and wistfulness for the river as raw canvas for artists.

5) Bridges and Walls: LA River, part 2

The Los Angeles River in downtown is getting new bridges and parks. But with the greening of the river may come “green gentrification.” DnA tours a disused railyard that will be turned into a park, hears about dreams for changes in the Lower LA River and talks to architect Frank Gehry and other stakeholders about LA County’s updated masterplan for the entire 51 miles of flood channel.

6) Bridges and Walls: Invisible Walls

There are walls that impact the communities they contain, but are naked to the eye. On today’s “Bridges and Walls” episode we explore three examples of invisible walls: the boundaries that mark gang territories; zoning codes that divide communities; and the West LA eruv, a ritualistic fence that allows Orthodox Jews to perform certain tasks on Shabbat, the traditional day of rest.

7) Bridges and Walls: The Future of Freeways

Los Angeles has fallen out of love with freeways. Or has it? Freeways were once liberating bridges between communities. Now they are polluting, rush-hour parking lots that form walls within the Southland. DnA looks at the health impact of living near freeways, a proposed new freeway in the High Desert, the optimistic origins of freeways, the havoc they wreaked on Boyle Heights, and how artists responded, and what they might look like in the future. Listen to the full show, above, or each story separately, below.

8) Bridges and Walls: The 4th Border

The final episode of DnA’s Bridges and Walls examines the “4th Border,” the Southland’s seashore. Undersea cables are being laid to connect LA virtually to the Pacific Rim and the rest of the world. But why do so many land in Hermosa Beach? What are we giving away in return for these connections? And how about using the ocean as an alternate route for traffic-weary Angeleno commuters? We’ll find out what it would take to ferry passengers between the beach towns. Listen to the full show, above, or each story separately, below.
