National Road Network of Costa Rica

National Road Network of Costa Rica (Spanish: Red Vial Nacional), are a series of numbered road routes that are managed through Costa Rica by the Ministry of Public Works and Transport (MOPT) and its subagency the National Road Council (Conavi).^[1]

According to the Inter-American Development Bank, in 2019 Costa Rica had the worst road network in Latin America, due to being under maintained, and having structural defects and deterioration in around 49% of the National Primary Routes network. Other countries in the area report an average of 20% in the same metric.^[2]

There are no high speed express routes but there are some two-lane trunk roads. Potholes are common in primary road routes. Many of the secondary or tertiary road routes are made of gravel or dirt. ^[3]
