The long-awaited overpass project at the Fonatur roundabout in San José del Cabo has reached 98% completion, according to Roberto Flores, Director General of Urban Development. Only minor finishing work remained as of mid-May, bringing the year-long construction effort close to its end.
The project, officially known as Glorieta Fonatur (also called Glorieta Mujeres Libres), replaces what had been one of the worst traffic bottlenecks in Los Cabos. The junction sits on Highway 1, the Transpeninsular Highway, and serves as the primary gateway connecting Los Cabos International Airport (SJD), downtown San José del Cabo, and the tourist corridor leading to Cabo San Lucas. Before construction began in May 2025, the roundabout handled more than 60,000 vehicles per day, routinely adding 20 to 30 minutes to airport transfers during rush hour.
Synchronized Signals Coming Online
Once complete, the project will include a synchronized traffic light system operating continuously along several key intersections. The coordinated signals will link the Fonatur roundabout with the Walmart intersection, Manuel Doblado Street, and the junction known as “La Y.”
“These traffic lights are the responsibility of the city through the Directorate of Public Safety and Municipal Transit,” Flores said. “They are necessary because there is pedestrian traffic in the area, and they will operate permanently.”
IMPLAN (Instituto Municipal de Planeación), the Municipal Planning Institute, is coordinating the signal synchronization across all the connected intersections leading into San José del Cabo. The goal is to maintain steady traffic flow and cut wait times for drivers.
A Year of Detours Nearing Its End
The project has progressed steadily since breaking ground. By late August 2025, it stood at 25% complete. It crossed the 50% mark by November 2025, ahead of schedule at that point. In February 2026, Mayor Christian Agúndez Gómez announced the overpass had reached 72% completion, with crossbeams already in place and paving underway.
The design sends four lanes of through-traffic beneath the existing roundabout via a below-grade underpass stretching roughly 1.5 kilometers. The roundabout itself will remain at surface level for local traffic movements. Drivers headed between the airport and the resort corridor will no longer need to merge through the circle.
Throughout construction, authorities routed traffic through detours including a gravel bypass near Costa Azul and a paved shortcut behind the Chedraui supermarket. The toll road bypass, or libramiento, also remained an option for avoiding the work zone entirely. With the project now at 98%, drivers should expect only minor disruptions in the final stretch.
