Nogales and San Luis Río Colorado Affected

For a second consecutive day, agricultural producers affiliated with the Frente Nacional para el Rescate del Campo Mexicano carried out coordinated blockades at two major Sonora–Arizona border access points – the Mariposa Port of Entry in Nogales and the highway connecting Mexicali to San Luis Río Colorado.

In Nogales, approximately 93 agricultural producers from Sinaloa blocked access to the Mariposa commercial gate, preventing the passage of cargo trucks. After negotiations involving local and U.S. transportation authorities, Index Nogales, and trucking representatives, a temporary agreement was reached to allow 50 semi-trucks to cross at 11:20 a.m.

The pause provided only minimal relief. On a typical day, approximately 3,000 trucks pass through the Mariposa crossing, highlighting the significant economic impact of even short-term interruptions.

Meanwhile, in Baja California, farmers from the Mexicali Valley blocked the highway into San Luis Río Colorado, stranding vehicles for hours. Organizers announced the blockade would continue until they receive a favorable response from federal authorities. A representative from the movement confirmed that the group’s national leader is currently in Mexico City in talks with federal officials.

Why this matters

In addition to slowing cross-border travel, these protests reflect growing frustration among Mexican agricultural workers over government policy, pricing, support, and long-standing structural inequality in the farming sector.

Border disruptions of this kind are not unusual in northern Mexico, but when they affect key ports like Nogales and San Luis Río Colorado, the impact is felt immediately on both sides of the border – slowing trade, delaying shipments, and straining cross-border supply chains.

While temporary agreements may ease congestion, the root causes of these protests remain unresolved.
