For many travelers, the bridge over the Tárcoles River is more than just a piece of infrastructure; it is a rite of passage. Known affectionately as the “Crocodile Bridge,” it is the spot where you pull over, stretch your legs, and marvel at the prehistoric giants sunning themselves on the muddy banks below before continuing your journey to the sun-soaked beaches of Jacó or Manuel Antonio.However, for the next few months, the thrill of seeing those massive American crocodiles will come with a side of necessary patience. Starting Monday, February 23, 2026, traffic on Route 34 (the Costanera Sur) will shift back to alternating one-lane travel as crews enter the heavy rehabilitation phase of the bridge’s superstructure.Why the Wait? The Infrastructure RealityWhile the Tárcoles Bridge is iconic, it is also a aging artery under immense pressure. Handling over 32,000 vehicles daily, the bridge has weathered years of seismic activity and heavy tropical rains. The current $6.7 million project, funded by the Central American Bank for Economic Integration, is 61% complete and aims to ensure the bridge stays standing for decades to come.According to the Ministry of Public Works and Transportation (MOPT), the upcoming phase focuses on the superstructure—the deck where vehicles and pedestrians actually move. This follows months of work reinforcing the underground foundations and supporting piers.The 2026 Travel Schedule: What You Need to KnowAuthorities have released a detailed timeline to help tourism operators and drivers plan ahead. If you are traveling through the Central Pacific this spring, keep these dates on your calendar:

The “Croc Watch” WarningIt is important to note that during this phase, the bridge is strictly a work zone. While the pedestrian sidewalk remains open for people needing to cross from one side of the river to the other, “crocodile watching” from the bridge is currently prohibited for safety reasons. With heavy machinery and narrow passing lanes, stopping to take photos on the bridge creates a hazard for both you and the construction crews.

Pro Tip: If you still want to see the crocodiles safely, visit the town of Tárcoles just south of the bridge. Many local operators offer boat safaris that take you right to the water’s edge, offering a much closer (and safer) view than peering over the railing.

How to Navigate the Delays Like a Pro

A Stronger Future for Route 34While the one-lane travel is a temporary headache, the end result is a bridge that is seismic-resistant and equipped with better pedestrian walkways and lighting. By mid-2026, the project is slated for completion, promising a smoother and safer journey to some of Costa Rica’s most beautiful destinations.In the meantime, take the delay as an opportunity to slow down, look at the lush scenery, and remember that in Costa Rica, the journey is just as important as the destination.
