Good news for anyone driving between San José and Costa Rica's Pacific coast: the Cambronero bridge on Route 1 is set to reopen at noon on Tuesday, November 3, almost two weeks earlier than planned. The crossing, at kilometer 71 on the stretch of the Inter-American Highway linking San Ramón in Alajuela with Esparza in Puntarenas, had been shut since the night of September 7, when a tractor-trailer slammed into the modular steel structure.
Repairs were no small job. Crews first had to build a temporary support tower, with some parts custom-made for the task, before they could dismantle damaged sections and remove the entire bridge deck for replacement. With that done, traffic can now flow again through Cambronero, though minor work will continue after reopening. Officials say those remaining tasks shouldn't disrupt drivers, but anyone passing the site should ease off the accelerator around the crews.
The modular bridge is a stopgap. This section of Route 1 has been battling ground instability, and a permanent fix is now in the pipeline. Bids are under review, with construction expected to start in early 2027. The plan involves stabilising the slope, removing the temporary bridge and rebuilding the road's two lanes. A third lane is being studied but hasn't been approved.
For travellers, this matters more than it might sound. Route 1 is the main artery for the classic Costa Rica road trip: the drive from the Central Valley out to Puntarenas, the ferry to Paquera and the beaches of the Nicoya Peninsula, or onward north toward Guanacaste's surf towns. Since September, anyone self-driving has faced long detours around the closed crossing. From November 3, that headache disappears.
If you're renting a car this month, plan around the bridge's noon reopening on the day itself, and expect the usual caution zones where crews are still working. The wider lesson is that Costa Rica's main highways can be vulnerable to landslides and damage in the rainy season (roughly May to November), so it pays to check road conditions before setting out, especially on routes crossing hilly terrain. With the closure lifted and the permanent repair still nearly a year off, the current window is a good one for that Pacific-coast drive.
