Andorra Activates Three-Lane Layout on La Unió Street to Boost Traffic Flow

La Unió Street now features three lanes between the Km0 and Dama de Gel roundabouts, with private vehicles prohibited from turning left onto Na Maria Pla to improve traffic circulation in Andorra's central valleys.

Overnight resurfacing and marking work on Thursday night allowed the layout to activate Friday morning, minimizing daytime interruptions. Heading from Km0 toward Dama de Gel, two lanes operate until the Na Maria Pla junction, where they narrow to one; buses alone may turn left there, while other traffic must continue ahead. In the reverse direction, from Dama de Gel, two lanes pass the Meritxell and Carlemany junctions: the right lane leads to Na Maria Pla, the left to Km0. A 30 km/h limit runs the full length, supported by fresh signage for safety.

The redesign removed restaurant terraces and most loading areas, though a compact delivery zone for transporters—positioned just beyond the Fener junction, where the downhill lane expands alongside the sidewalk—will open shortly next to the preserved bus stop. Pending work includes bus stop markings, the delivery zone outline, a pedestrian signal at Na Maria Pla, and bollards to restrict the bus-only turn.

Traffic agents assisted drivers Friday amid initial uncertainty, especially on the Na Maria Pla restriction, providing a grace period before enforcement ramps up. State Secretary for Energy Transition, Transport and Mobility David Forné and Mobility Agency director Daniel Boneta visited the site mid-morning to assess operations.

Forné described the changes as a way to streamline movement, enhance safety and flow, and ease pressure at bottlenecks including the Km0 roundabout—previously jammed in the "cacahuet" zone—and Dama de Gel. He highlighted benefits for pedestrians, shorter peak-hour delays, and overall quality of life gains. The initiative builds on recent turbo-roundabouts and reversible lanes along this vital route linking Obac road, General 1, and the central valleys.

Forné praised the nighttime efforts by contractors and the Mobility Agency, along with close cooperation among Andorra la Vella, Escaldes-Engordany, and government bodies on the shared-parish road. He called the delivery adjustment a last-minute fix that preserves the three-lane advantages, while noting a brief adaptation phase for locals, tourists, and regular users.
