Aerostar Invests $500,000 in Main Access Road at SJU Airport: Two Weeks of Expected Traffic Delays

Aerostar Puerto Rico, the company that operates the Luis Muñoz Marín International Airport (LMM) in Isla Verde, Carolina, began work on Wednesday, September 9, at 6:00 a.m., on an approximately $500,000 rehabilitation of the main entrance and exit road to the terminal, a project expected to last about two weeks that the company warns could cause traffic backups for passengers and for anyone picking up or dropping off travelers ¹³.

Of the total investment, about $400,000 is going specifically toward rehabilitating the pavement of the airport access road, while another $100,000 is being invested in repairing the floor of the second level of the multi-story parking garage and the central pedestrian bridge connecting terminals B and C ¹³. The work includes removing the existing epoxy system, correcting the surface, applying a new anti-slip floor treatment, and sealing drainage channels to reduce water leaks ²⁴.

Jorge Hernández, president of Aerostar Airports Holding, explained that the intervention is part of ongoing maintenance of the airport's infrastructure. "This work is necessary to keep in optimal condition a road that passengers, employees" and visitors travel through daily, Hernández said, acknowledging that the project "can generate temporary vehicular congestion, which is why we urge our passengers to plan their trip" ¹⁴.

This is not the first phase of Aerostar's road maintenance program at LMM. The company already completed similar work on levels 3 through 6 of the multi-story parking garage before moving equipment to the second level and the main access road ¹². Luis Muñoz Marín Airport is Puerto Rico's main air gateway, with thousands of passengers traveling daily along its access road toward terminals A, B and C.

What it means for you

If you have a flight scheduled over the next two weeks, leave home earlier than usual. Aerostar warned the work could cause lines and extra delays both for people driving their own vehicle to the airport and for those using Uber, taxis, or hotel shuttle services ²³. The recommendation also applies to people who are simply going to the airport to pick up or drop off a passenger, since the congestion is expected on the access road before reaching the terminals, not inside them ¹.

Those who regularly park on the second level of the parking garage should also anticipate that level being under floor-repair work, so it's worth planning to use another level or short-term parking if possible ¹³. The central pedestrian bridge between terminals B and C is also part of the work, so travelers who rely on that route to switch terminals should plan for alternate routes inside the airport ³⁴.

How to do it / Checklist

1. Check your flight time and leave home or your starting point with at least 30 to 45 extra minutes beyond what you'd normally allow to reach LMM ²³.
2. If you're parking, consider avoiding the second level of the multi-story garage while the work is underway and choose another available level instead ¹.
3. If you're picking up or dropping off a passenger, coordinate the meeting point with extra time in mind, since the main access road is the one under rehabilitation ¹³.
4. If you need to walk between terminals B and C, ask at airport information about alternate routes while the central pedestrian bridge is being repaired ³⁴.
5. Follow the official digital platforms of Aeropuerto SJU (social media and website) for last-minute notices about partial closures or changes to the access route ²³.
6. If you're traveling with large luggage or have reduced mobility, consider requesting extra assistance or arriving with more of a buffer, since vehicle lines could lengthen the walk from the drop-off point into the terminal ¹.

What's next

Aerostar did not give an exact completion date beyond estimating the work would take "approximately two weeks" from its September 9 start, which points to the project wrapping up around late September 2026 ³. The company did not rule out continuing with other areas of the airport complex once this phase concludes, as part of its preventive maintenance program, given that it already finished levels 3 through 6 of the parking garage before this intervention ¹². Once complete, both the access road and the second parking level and central pedestrian bridge are expected to have renewed surfaces and sealed drainage systems, reducing the risk of leaks during the rainy season ¹⁴.
