Route 177, which connects the cantons of Escazú and Alajuelita in San José province, will be closed to traffic for roadway improvements, the Ministry of Public Works and Transportation (MOPT) announced.

Authorities said a 1-kilometer (0.6-mile) section of the route will be closed 24 hours a day starting Monday, May 11, and is expected to remain shut for the next eight months.

The project includes reconstruction of the asphalt surface, construction of a bridge over the Agres River, installation of an expanded wastewater drainage system designed to handle increased rainfall, construction of new sidewalks, and repainting of road markings.

The reconstruction of this key roadway is budgeted at more than $4 million and will be funded by the ministry.

Traffic officers have been deployed and warning signs installed to help manage vehicle flow. Drivers are advised to plan for possible delays.

Officials expect the upgraded road to be inaugurated in January 2027.

The Route 177 project is part of broader national infrastructure improvement efforts underway across the country. Recently, toll booths along National Route 1, the main highway connecting the capital to Juan Santamaría International Airport (SJO), were removed to improve traffic flow.

MOPT oversees Costa Rica’s roads, ports, airports and public transportation systems.
