NROC says some 6,384 vehicles benefited from the measures

Temporary Traffic management measures implemented at the Mammee Bay Toll Plaza have successfully eased weekend congestion on the North-South Highway, allowing motorists to move through the toll plaza without delay during one of the busiest travel weekends of the year.

The measures that were implemented faced their first major test during the Reggae Sumfest weekend, which generated high traffic volumes along the North-South Highway. Previously, on July 19, 2025, a total of 5,522 vehicles exited the Mammee Bay Toll Plaza. 

Also, on Saturday July 11, 2026, approximately 5,665 vehicles exited the Mammee Bay Toll Plaza. Preliminary traffic data indicates that approximately 6,384 vehicles exited the Mammee Bay Toll Plaza on Saturday, July 18, 2026.

Details of improvement measures 

The improvements were the result of discussions between the Government of Jamaica, through the National Road Operating and Constructing Company Limited (NROCC), and the operators of the North-South Highway, Jamaica North South Highway Company. Those discussions led to several immediate measures being implemented, including the construction of two temporary spill-over lanes to address recurring traffic spikes at the toll plaza.

Importantly, these temporary works were executed at no cost to the Government of Jamaica. NROCC monitored traffic conditions throughout the weekend and confirmed that the measures performed as intended. Despite the significant increase in demand, motorists continued to move through the toll plaza without significant delays, demonstrating the effectiveness of the temporary measures introduced to improve traffic flow. 

Commenting on the preliminary results from the temporary measures, NROCC Managing Director, Stephen Edwards says, “the high-traffic weekend provided the ideal opportunity to test the effectiveness of the temporary traffic mitigation measures, including the construction of the two additional toll lanes at Mammee Bay. The successful outcome demonstrates that the measures are delivering as intended.” 

Continuing, Edwards adds, “our priority is ensuring motorists can move safely and efficiently along the corridor, particularly during periods of peak demand. The temporary spill-over lanes will remain in use while JNSHC advances its planned permanent expansion of the Mammee Bay Toll Plaza to accommodate continued growth in traffic demand. We will continue working closely with our partners to identify and implement practical solutions that improve traffic flow and enhance the experience for all road users.”

NROCC says it will continue working closely with the Toll Road Operators to monitor traffic patterns and implement practical solutions that improve the level of service at the across the National Toll Road Network.
