Puerto Rico Highway 22 (PR-22) and Puerto Rico Highway 5 (PR-5) are limited access toll highways serving Puerto Rico's northern coast and the San Juan metropolitan area. PR-22, also known as José de Diego Expressway, is a 52-mile, four-and six-lane highway with seven toll plazas, extending west from San Juan to Hatillo. It is the busiest highway in the commonwealth. PR-5, also known as Río Hondo Expressway, is a 2.5-mile extension of PR-22 (the facility is four miles in total) south to Bayamón, where its single toll plaza is located, that opened in 2006. Both facilities were leased in 2011 to a concessionaire who will rehabilitate, operate and maintain the toll roads over a 40-year period, which was later extended to a 50-year term.
