Drivers heading along Route 34 should prepare for delays starting Monday, as traffic on the bridge over the Tárcoles River shifts back to one lane. The measure supports ongoing rehabilitation work on the structure, which connects key coastal areas. Authorities from the Executive Unit for the Tárcoles River Bridge Rehabilitation Project stated that the one-lane restriction begins February 23 and runs through March 27.
This allows crews to focus on the bridge’s superstructure, the area where vehicles and pedestrians cross. Peak hours may see backups, so travelers need to account for extra time. The project pauses restrictions during Holy Week to ease movement for locals and visitors. From March 28 to April 5, both lanes stay open, aiding tourism and commerce in the region.
Nighttime work adds another layer. Between March 15 and April 20, full closures of both lanes occur from 9 p.m. to 5 a.m. for installing seismic isolators. These closures happen on select nights, not back-to-back, with exact dates shared closer to the time.
A short one-lane period follows in May. From May 4 to May 9, traffic reduces again to install a bridge joint, essential for the structure’s operation and strength. Officials released these details on January 23, giving a full month for drivers, businesses, and tourism operators to adjust plans.
The bridge, on the Costanera Sur, handles heavy flow between San José and Pacific spots like Jacó and Manuel Antonio. Rehabilitation stands at 61 percent complete, addressing seismic risks and wear from years of use. Funding comes from the Central American Bank for Economic Integration, with $6.73 million allocated under the Emergency Program for Comprehensive and Resilient Infrastructure Reconstruction. The effort aims to secure the bridge against earthquakes and extend its service life.
Travelers can check updates through the Ministry of Public Works and Transportation channels. Alternate routes, like Route 27, offer options but may add distance. This work follows earlier phases, including foundation repairs, now shifting to upper sections. Completion is set for mid-2026, promising smoother travel ahead.
