In addition to the national highways, the government has embarked on an expansive reconstruction of spur secondary routes, which connect smaller towns to the trunk routes. In the last few years the government constructed a 106-kilometer toll road that connects Santo Domingo with the country's northeastern peninsula. Travelers may now arrive in the Samaná Peninsula in less than two hours. Other additions are the reconstruction of the DR-28 (Jarabacoa – Constanza) and DR-12 (Constanza – Bonao). Despite these efforts, many secondary routes still remain either unpaved or in need of maintenance. There is currently a nationwide program to pave these and other commonly used routes. Also, the Santiago light rail system is in planning stages but currently on hold.
