History

Puerto Rico Interstate 2 was one of three routes approved as part of the National System of Interstate and Defense Highways by the Federal Highway Administration (FHWA) on May 27, 1983. The initial 91.0 mile long route of PRI-2 followed PR 2 from the intersection of PR 2 Spur north of Mayagüez to Aquadilla and east to PR 18/PRI-1 in San Juan. The American Association of State Highway and Transporation Officials (AASHTO) followed with approval of PRI-2 on October 1, 1983.

An long extension of PRI-2 from Mayagüez south and east to Ponce was authorized by the FHWA on December 17, 1993 under 23 U.S.C. 139 (c) (Pesquera, 1994). The 44.52 mile long stretch concluded in the Ponce urbanized area with then Future PR 52. AASHTO concurred with the extension on April 10, 1994.

The construction of PR 22 (Autopista Jose de Diego) from San Juan west to Arecibo superseded PR 2 as the through route. The final section of the toll road opened to traffic on March 30, 1995. The FHWA Puerto Rico Division substituted PR 2 for PR 22 in action effective in March 1996 under 23 U.S.C. 139 (c). The formal relocation of PRI-2 was approved by AASHTO on April 19, 1998.
