Puerto Rico Highway 10 (PR-10) is a major highway in Puerto Rico. The primary^[3] state^[4] road connects the city of Ponce in the south coast to Arecibo in the north; it is also the shortest route between the two cities.^[5]

Construction on the modern PR-10, a new 68.26-kilometer (42.41 mi) highway, began in 1974. The highway is being built parallel to the old PR-10;^[6] that road is now signed PR-123.^[7][8] Most of the new PR-10 is now complete, with an approximately 10-kilometer (6.2 mi) stretch still remaining to be finished. In its current state it is a freeway only in the completed portions, which consists of over three-fourths of the highway.

In May 2010, Autoridad de Carreteras estimated the road would be completed in 2015, at a cost of $500 million. Upon completion, the highway is expected to become one of the two major roads on the island that cross the Cordillera Central mountain range. The first section of the road was inaugurated in the year 2000. After "more than 40 years" since the project was initiated, as of 22 January 2017, 10 kilometers (6.2 mi) remained to be completed.^[9]
