Puerto Rico Highway 204 (PR-204) was previously a short connector road between PR-22 and PR-2 in Barceloneta, Puerto Rico but was renumbered Puerto Rico Highway 140, and a new PR-204 was built in Las Piedras, Puerto Rico, which connects PR-30 and PR-198 to PR-183 in the municipality.[2] The new connector was constructed to better serve residents of the town which can only enter through the exit to PR-183 and has a high frequency of long congestion and traffic jams. The main movie theater in the east coast can be accessed by the road.[3]
