PR-22 (also part of unsigned Interstate PR2) is an 84.3 km (52.4 mi) 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 José 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.
