Puerto Rico Highway 22

PR-22 (also part of unsigned Interstate PR2) is a 51-mile (83-km) long toll road in the north coast of Puerto Rico that connects the cities of San Juan and Hatillo. The road is also known as the José de Diego Expressway (Spanish: Expreso De Diego), and is part of unsigned Interstate PR-2. It is a 4-lane road for much of its length, but expands to up to 12 lanes in the San Juan metro area. The road is frequently congested, in particular during rush hour due to heavy commuter traffic.

The road is part of the U.S. Interstate Highway System.

Route description

PR-22 is Puerto Rico's most traveled highway. PR-22 runs parallel to PR-2 and is concurrent with unsigned Interstate Highway PRI-2. Unlike PR-22, PR-2 is not a controlled-access road, and has numerous traffic signals throughout the full run of its course. The construction of highway PR-22 reduced congestion on PR-2. The eastern terminus is at PR-26 (a non-tolled freeway) in Santurce, and passes through the Minillas Tunnel before its terminus at PR-26. The freeway bypasses all of the cities PR-2 passes through (see below under "Course of the Expressway"). PR-22's western terminus is at PR-2 in Hatillo. From there, PR-2 and Interstate PRI-2 continues to Aguadilla and Mayagüez, ending in Ponce.
