Route 27 in Costa Rica operated with reversible lanes between 2 p.m. and 6 p.m. on July 12 [1].
The measure was implemented to manage the surge of traffic as beachgoers returned home following the school break [1]. Because Route 27 serves as the primary artery between the capital and the coast, congestion during holiday transitions often creates significant delays for thousands of motorists.
The traffic reversal affected the entire 47-kilometer (29-mile) stretch of the highway connecting San José and the Pacific coast [1]. During the specified window, every lane on this segment was dedicated to a single direction to expedite the flow of vehicles heading inland [1].
This logistical challenge follows a period of instability for the highway. In May, the Ministry of Public Works said Route 27 was expected to partially reopen after a major sinkhole cut off the main highway between San José and the Pacific coast [2]. The road collapse had restricted access to the coastal region earlier that month.
Authorities have used similar traffic management strategies for other high-volume periods this year. Ricardo Hernández said the measure also applied on Easter Sunday, the final day of the Semana Santa [3].
Drivers were advised to follow official signage and police directions during the four-hour window to ensure safety and efficiency. The use of reversible lanes is a recurring tool for the government to mitigate the bottlenecks that occur on the narrow corridors leading into San José [1].
“Route 27 will operate with reversible lanes between 2 p.m. and 6 p.m. on July 12, 2026”
The reliance on reversible lanes highlights the fragility of Costa Rica's primary coastal infrastructure. Between the recurring congestion of holiday travel and the structural failures caused by sinkholes, Route 27 remains a critical point of failure for the nation's transport network, necessitating temporary tactical measures to prevent total gridlock.
