A day at the beach shouldn’t begin and end in a queue of brake lights—but that’s the reality facing anyone who plans to drive Route 34 in the coming year. The landmark bridge over the Tárcoles River is due for extensive structural reinforcement under CONAVI’s PROERI programme (https://www.conavi.go.cr/). Engineers have confirmed alternating one‑lane traffic during daylight hours and selected overnight closures beginning in the second half of 2025 and likely extending into early 2026. Precise work charts and closure calendars are still pending, yet even preliminary lane controls will add serious time to any road trip. If you’d rather track tides than traffic lights, the smart workaround is a twenty‑five‑minute hop with Costa Rica Green Airways into nearby Quepos.
The Bridge Project at a Glance
The rehabilitation will reinforce beams, deck plates and seismic joints, and widen the walkway for safer crocodile viewing—after work finishes. Funding flows through PROERI, and the contractor must publish a month‑by‑month closure calendar thirty days before the first jackhammer hits steel. Until that document appears on the MOPT advisory feed (https://www.mopt.go.cr/), treat all timelines as provisional.

How Long Could the Drive Take?
Even a 20‑minute stop at Tárcoles magnifies behind freight trucks and holiday traffic on Route 27. The table below blends GPS data from typical weekdays with field reports from drivers who faced lane controls on previous bridge projects.
| Route | Normal Drive (dry weekday) | With Lane Control* | Holiday or Rain‑Season Worst‑Case** |
|---|---|---|---|
| San José → Jacó | 1 h 30 m | 2 h 10 m | 3 h + |
| San José → Manuel Antonio | 2 h 30 m | 3 h 30 m + | 5 h + |
| San José → Dominical/Uvita | 3 h 15 m | 4 h 30 m + | 6 h – 7 h |
*Assumes one active work lane and alternating 20–30‑minute stops.
**Christmas, New Year’s, Easter or afternoon cloudbursts can double or triple delays. Travellers have clocked seven‑hourjourneys to Quepos when Route 27 was already jammed before they reached Tarcoles.
Why Rain and Holidays Multiply Delays
Tropical downpours force crews to pause machinery, and every pause extends the queue. Holiday weekends swell traffic volume on Route 27 as far back as Atenas. Add lane control at the bridge and the result is a rolling parking lot.
Alternate Over‑Land Routes and Their Drawbacks
Route 27 through Puriscal adds 60 kilometres of mountain switchbacks, often riddled with landslides. The Cerro de la Muerte bypass climbs to 3 400 metres and is known for fog so thick your hazard lights disappear. The Puntarenas–Paquera ferry helps only if you’re already Nicoya‑bound and ties you to a fixed sailing slot. None consistently beat the bridge delay—and all burn extra fuel.
Twenty‑Five Minutes vs. Three Hours: The Flight Alternative
Commercial service from San José to Quepos covers the distance in the time it takes to finish a cup of coffee—twenty‑five minutes airborne and fifteen minutes by shuttle to Manuel Antonio Beach. Even on a clear highway day, that’s an hour saved each way; on a lane‑control weekend, you could reclaim half a day of holiday.
| Mode | Total Time SJO → Manuel Antonio* | Stress |
|---|---|---|
| Costa Rica Green Airways flight | 25 m airborne + 15 m shuttle | Low |
| Car (no delays) | 2 h 30 m | Moderate |
| Car (lane control) | 3 h 30 m – 4 h | High |

How to Plan Ahead
Reserve morning flights early; the first departure fills fast once delays trend on social media.
Pack dive gear or bikes under the Full Fare’s 50‑pound allowance—see the baggage guide.
If you must drive, leave San José before dawn and schedule no tight commitments for arrival day.
Frequently Asked Questions
Will the bridge ever close 24/7?
CONAVI says no daytime full closures—only alternating lanes by day and some overnight shutdowns. Exact dates will be released a month in advance.
Can I still see the famous Tarcoles crocodiles?
The pedestrian walkway will be fenced during construction. Book a boat safari from Tarcoles town for a safer view.
Are pets allowed on flights?
Small pets (≤ 8 kg with soft carrier) fly in cabin. Larger animals travel in a ventilated baggage bay. Reserve 48 hours ahead.
Final Word
Charts and exact closure dates are still to come, but the takeaway is clear: mid‑2025 through early 2026 will be unpredictable for Route 34 drivers. Save your patience for sunset cocktails—let a twenty‑five‑minute flight lift you over the bottleneck.
