San Antonio’s Interstate 35 South Side became the scene of a preventable tragedy Friday morning when a pedestrian was struck and killed by an 18-wheeler near the interchange with Loop 410. The incident, reported by KSAT and confirmed by San Antonio Police Department (SAPD) officials, occurred just before 7:15 a.m. Inbound lanes near the Roosevelt Avenue overpass—a stretch of highway notorious for its high-speed traffic, fragmented pedestrian infrastructure, and chronic lack of safe crossing points for those navigating the corridor on foot.
This wasn’t just another traffic fatality. It was a stark reminder of how urban highways, designed for speed and volume, routinely fail the most vulnerable among us—people without cars, often low-wage workers, the unhoused, or those relying on public transit who must cross deadly asphalt to reach jobs, clinics, or shelters. In Bexar County alone, pedestrian deaths on interstates and state highways have risen 34% since 2020, according to Texas Department of Transportation (TxDOT) data, outpacing population growth and signaling a systemic failure in road safety design.
The victim, identified by SAPD as 52-year-old Marcus Ellison, was a longtime employee at a warehouse distribution center in the Southton industrial zone. Colleagues described him as a quiet, dependable man who walked nearly three miles each way to perform since he couldn’t afford vehicle maintenance or insurance. “He’d be out there before dawn, rain or shine, heading to his shift,” said Maria Lopez, a coworker who spoke with Ellison daily at the breakroom coffee pot. “Nobody thought it’d end like this. Nobody should have to walk that far just to earn a paycheck.”
Ellison’s death exposes a painful contradiction in San Antonio’s infrastructure priorities. Even as the city has invested hundreds of millions in downtown revitalization, riverwalk expansions, and smart traffic signals for affluent corridors, the South Side—home to some of the city’s highest concentrations of poverty and minority residents—remains structurally isolated by barriers like I-35, which functions less as a connector and more as a moat. A 2023 study by the University of Texas at San Antonio’s Urban Future Lab found that South Side residents are 2.8 times more likely to die in a pedestrian-vehicle collision than those in North Side neighborhoods, despite similar population densities.
“This isn’t about individual negligence—it’s about design violence,” said Dr. Elena Rodriguez, professor of urban planning at UTSA and author of Concrete Barriers: How Highways Divide American Cities. “When you build highways without pedestrian overpasses, adequate lighting, or clearly marked crosswalks in areas where people demonstrably need to cross, you’re not just accepting risk—you’re engineering it. Marcus Ellison didn’t fail the system. The system failed him.”
TxDOT’s own Pedestrian Safety Action Plan, updated in 2022, acknowledges that 60% of fatal pedestrian crashes on state highways occur in urban areas with inadequate sidewalk continuity or crossing infrastructure. Yet funding for remedial measures—like installing pedestrian hybrid beacons (PHBs), widening shoulders, or reducing speed limits in conflict zones—remains chronically undersubscribed. In Bexar County, only 12% of identified high-risk pedestrian corridors have received any safety upgrades since 2020, per TxDOT’s quarterly performance reports.
SAPD Traffic Division Sergeant James Reeves confirmed the preliminary investigation indicates no signs of impairment or reckless driving by the truck operator, who remained at the scene and cooperated fully. “We’re treating this as a tragic accident, not a criminal act,” Reeves said. “But that doesn’t mean we shouldn’t ask why a man had to be in that lane at all.” He noted that officers frequently respond to pedestrians attempting to cross I-35 between exits where no legal crossings exist—a behavior driven not by recklessness, but by necessity.
The human cost of this infrastructure gap is measurable. According to the National Complete Streets Coalition, every mile of urban highway lacking safe pedestrian crossings correlates with a 17% increase in fatality risk for nearby residents. In San Antonio’s South Side, where median household income is $38,000—nearly half the city average—and car ownership rates lag 22% behind the metropolitan norm, walking isn’t a choice. it’s a survival strategy.
Advocates are calling for immediate action. The Alamo Area Metropolitan Planning Organization (AAMPO) has long proposed a pedestrian overpass at the Roosevelt Avenue corridor, estimated at $4.2 million—a fraction of the $120 million recently allocated for expanding I-35’s northbound lanes near downtown. “We’re not asking for a moon shot,” said Carlos Mendez, director of Walk San Antonio, a pedestrian advocacy group. “We’re asking for a sidewalk that doesn’t end at the edge of a freeway. We’re asking for dignity in design.”
As San Antonio grapples with rapid growth and worsening traffic congestion, the city faces a defining question: Will it continue to build highways that move cars efficiently while treating human lives as externalities? Or will it finally recognize that true mobility justice means designing infrastructure where the most vulnerable aren’t forced to gamble their lives just to get to work?
The morning Marcus Ellison walked onto I-35, he wasn’t thinking about traffic engineers or budget allocations. He was thinking about his shift, his paycheck, the quiet dignity of showing up. Now, his absence echoes in the breakroom, in the empty space beside his locker, and in the silence of a city that still hasn’t learned how to see the people walking beside its highways.
What would it take for San Antonio to stop treating pedestrian deaths as inevitable—and start treating them as unacceptable?
