PR-52 Highway in Full Transformation: $141 Million to Rebuild Bridges and Pavement from San Juan to Ponce

The Roads and Transportation Authority (ACT) began work this week on four bridges on the Luis A. Ferré Expressway (PR-52) between kilometers 97.6 and 99.2 in Ponce, as part of a $24.4 million investment that will maintain partial lane closures through 2029 ¹. The project is part of a massive plan exceeding $140 million to rebuild multiple segments of the island's main north-south highway.

Bridges 1067, 1068, 1069, and 1070 will receive complete superstructure replacements, including installation of new slabs, concrete and metal barriers, lighting systems, signage, and traffic control devices ². During construction, two lanes will remain open in each direction, though drivers should expect temporary detours at the PR-52 and PR-10 intersection.

Governor Jenniffer González Colón formally inaugurated the work on July 11 alongside DTOP Secretary and ACT Executive Director Edwin E. González Montalvo and Ponce Mayor Marlese Sifre Rodríguez ². "Our primary objective is not only improving road conditions but protecting drivers' lives," the governor stated.

The Full Picture: $141 Million for PR-52

The Ponce bridge work is just one piece of a comprehensive PR-52 renovation, Puerto Rico's longest toll highway spanning 90 kilometers connecting San Juan to Ponce. Four projects are currently active simultaneously ³:

• San Juan-Caguas (km 0-14.2): Pavement reconstruction at $46.7 million with 100% federal funding, estimated completion May 2028.
• Cayey: Emergency slope stabilization at $41.6 million with FHWA emergency funds. Two of three slopes completed; the third under construction targeting October 2026.
• Ponce pavement (km 102.1-106): General rehabilitation at $28.9 million including bridges, shoulders, ramps, and signage.
• Ponce bridges (km 97.6-99.2): The $24.4 million project that launched this week.

The combined investment exceeds $141 million, funded through federal funds (between 80% and 100% depending on the segment) and state contributions ³.

The Numbers That Matter

PR-52 carries approximately 156,100 vehicles daily on its busiest segments and around 56,000 on the Ponce stretch ¹⁴. It is the island's second-busiest toll highway and the main artery for commerce between the San Juan metro area and the southern coast.

The bridge project generates approximately 50 direct jobs ¹, while island-wide more than 500 road construction projects are being executed simultaneously with a total investment of $1.4 billion, according to Secretary González Montalvo ⁴. On major highways alone -- PR-52, PR-53, PR-26, PR-30, and PR-60 -- there are 16 active projects totaling $324 million.

Additionally, FEMA allocated $95.1 million in July for 47 recovery and mitigation projects, including $14.1 million for San Juan port dock repairs and $1.1 million for a bridge repair on PR-250 in Culebra ¹.

What This Means for You

If you travel PR-52 between San Juan and Ponce -- whether for work, business, or tourism -- you will encounter active construction zones along virtually the entire route for the next two to three years. Lane closures are temporary and rotating, but traffic will be slower, especially during peak hours and weekends.

Tolls continue operating normally under the public-private partnership concession with Abertis/Puerto Rico Toll Roads, which has managed the highway since October 2023. No toll rate changes related to construction have been announced.

How to Handle It / Checklist

• Before you leave: Check the DTOP interactive map (dtop.pr.gov/mapa-interactivo) for updated detours and active construction zones.
• Use Waze or Google Maps: The ACT recommends activating real-time navigation for closure alerts.
• Plan extra time: Add 15-30 minutes to your usual San Juan-Ponce trip, especially during work hours (9 AM - 5 PM when closures are active).
• Reduce speed: In construction zones, respect reduced speed limits and maintain safe following distance. A maintenance worker died in May on PR-30 when a distracted driver breached the work zone ⁴.
• Alternate route: If your destination is Ponce and congestion is severe, consider PR-2 along the west coast as an alternative, though the trip is longer.

What Comes Next

The four-bridge project in Ponce has an estimated completion date of 2029. The Cayey stabilization segment should be completed by October 2026, and the San Juan-Caguas reconstruction by May 2028.

DTOP has requested an additional $115 million from the Fiscal Oversight Board to expand the rehabilitation program to all 78 municipalities ². So far, $547 million has been disbursed in road work since January 2025, covering 42 municipalities and 46 roads, with an allocated budget of $82.1 million for fiscal year 2026-2027.

For PR-52 drivers, the message is clear: the highway is undergoing a full transformation. The inconveniences will be real, but the promised result is a safer, more durable roadway for decades to come.
