PORT-AU-PRINCE, Haiti (AP) A major highway in Haiti will get an overhaul with the help of $50 million from the Inter-American Development Bank.

The bank’s grant aims to repair parts of National Highway #1, which connects Haiti’s two biggest cities and busiest seaports, Port-au-Prince and Cap-Haitien.

The goal is to foster economic development by making road transport from the north to Port-au-Prince more efficient and safer. This includes widening shoulders and installing guardrails, speed bumps and road signs. The program also seeks to educate motorists about road safety.

Few roads in Haiti are acceptable. The IDB says only 15 percent of Haiti’s 2,174 miles (3,500 kilometers) of roadways is in good condition.

IDB announced the grant Friday.
