A New Traffic Solution for Mendoza's East Access

Mendoza, Argentina's premier wine region located at the foothills of the Andes, has implemented a 200-meter bypass at the Don Bosco bridge on the East Access (Provincial Route 22). This strategic corridor connects the department of Maipú—one of Mendoza's most important agricultural districts—with the provincial capital, Ciudad de Mendoza (Greater Mendoza).

The measure was taken after detecting critical traffic bottlenecks that affected thousands of commuters since the start of major remodeling works. The original detour toward the South Collector Road created a severe congestion point at the intersection with Don Bosco lane.

Traffic Delays Detected

  • Morning rush hour (7:30-8:15): 20-minute average delay
  • Afternoon rush hour (17:30-18:00): up to 30-minute delay
  • Peak maximum reported: 45 minutes by drivers

New Detour Scheme

  1. Near Serpa bridge: detour to South Collector Road
  2. Before Don Bosco bridge: temporary return to main road
  3. After Don Bosco bridge: new detour to South Collector Road until Cervantes

Collector Road Paving Project

Governor Alfredo Cornejo ratified an agreement to pave 26 kilometers of the North and South Collector Roads of the East Access through Decree 1149, published in the Official Bulletin.

The project will benefit the districts of Coquimbito, Rodeo del Medio, Fray Luis Beltrán, and San Roque—all historic wine-producing areas within Maipú department—improving their connectivity with downtown Mendoza and the metropolitan area.

Funding Source Percentage Amount
Mendoza Province 70% USD 7 million
Maipú Municipality 30% USD 3 million
Total Investment USD 10 million

Important: Provincial funds are not a loan and do not need to be repaid by the Municipality, as determined by legal authorities.
