Construction begins on fourth lane of Buenos Aires-La Plata highway

Autopistas de Buenos Aires SA (Aubasa), a state-owned company, has announced the commencement of construction for a fourth lane on the Buenos Aires-La Plata highway. This expansion project will add a new lane stretching approximately 20 kilometers, from Acceso Sudeste (kilometer 11.5) to the Hudson toll station (kilometer 30.45), specifically for traffic heading towards the provincial capital.

The project is designed to enhance road safety, improve traffic fluidity, and reduce travel times for the daily commuters using this route. The expansion benefits the municipalities of Avellaneda, Quilmes, and Berazategui. In addition to the new lane, the existing three lanes will be repaved, and a new asphalt layer will cover all four lanes to ensure a uniform surface.

Work is proceeding on two fronts simultaneously. The first phase, from km 11.5 to km 20, is 70% complete and involves constructing the fourth lane near Nuevo Quilmes, along with laying a conduit for fiber optics. Nighttime repaving is also being conducted to minimize traffic disruption. The second phase, from km 20 to km 30.45, is 50% complete and includes building a retaining wall at km 20, as well as pothole repair and repaving.

Aubasa had previously announced the highway expansion in October of the previous year to alleviate peak-hour congestion. This project is part of the company's 2024-2027 plan. Upon full completion, estimated for August 2027, the highway will feature four lanes in each direction, totaling eight lanes along the 19-kilometer stretch between Buenos Aires and Hudson.
