Tanzania is spending Tsh12.6 billion ($4.8 million) to upgrade key infrastructure inside the Serengeti National Park, part of a broader effort to improve access to the country’s most visited wildlife reserve while strengthening its ability to withstand shifting weather patterns.

Officials say the program is designed to support both conservation work and tourism by improving roads and crossings that are often affected during heavy rains. The Serengeti, a UNESCO-listed ecosystem, is central to Tanzania’s tourism industry and one of Africa’s most recognized protected landscapes.

Each year, the park draws hundreds of thousands of international visitors and remains best known for the annual migration of more than two million wildebeest, zebras and gazelles. Tourism contributes significantly to Tanzania’s foreign exchange earnings and supports jobs across transport, hospitality and conservation services.

For government planners, maintaining reliable access to the park has become increasingly important as visitor numbers rise and weather conditions become less predictable.

Road works farget key access route

The largest share of the funding is going toward rehabilitation of the 121-kilometer Ndabaka–Seronera road, a major route linking western Tanzania to the central Serengeti.

The Tsh4.5 billion ($1.7 million) project involves full re-grading of the road, construction of seven box culverts and raising sections prone to flooding. Work began in June and is scheduled for completion in December.

Authorities say the upgrades are aimed at reducing seasonal disruptions that can cut off parts of the park during heavy rains, affecting both tourism operations and park management activities.

A further Tsh8.1 billion ($3.1 million) has been set aside for additional infrastructure, including bridges and river crossings at Banagi, Mti wa Rangi, Naabi, Kwa Bona and Mokas. Geotechnical assessments have already been completed, with detailed engineering designs now underway ahead of construction.

Balancing infrastructure and conservation

Officials at Tanzania National Parks (TANAPA) say the works are being carried out under strict environmental and engineering standards to ensure the park’s ecological integrity is not compromised.

“The Sixth Phase Government under President Samia Suluhu Hassan, through the Ministry of Natural Resources and Tourism, is investing significantly to ensure that the efforts undertaken to market Destination Tanzania are matched by equally strong investments in infrastructure, so that visitors find quality facilities and services on the ground,” said Catherine Mbena, assistant conservation commissioner for corporate communications at TANAPA.

Conservation leaders say infrastructure development inside protected areas must be carefully managed to avoid disrupting wildlife movement and fragile ecosystems.

“Our policy objective is to ensure that infrastructure development supports conservation rather than compromises it,” said TANAPA Conservation Commissioner Musa Nasoro Kuji. “Reliable transport infrastructure strengthens park management, improves visitor experience, enhances emergency response capability and supports sustainable tourism, while safeguarding the ecological integrity of the Serengeti for future generations.”

Engineering challenges in Serengeti terrain

Engineers working in the park say the terrain and environmental sensitivity require careful planning at every stage of construction.

“Every infrastructure intervention inside Serengeti must meet rigorous engineering and environmental standards,” said TANAPA engineer Abubakari Avanda Mshamu. “We ensure construction materials and designs are compatible with the ecosystem and its status as a UNESCO World Heritage Site. Our aim is infrastructure that withstands extreme weather while preserving its outstanding universal value.”

Long-term economic and tourism goals

Government officials describe the program as part of a longer-term effort to support tourism, one of Tanzania’s largest sources of foreign exchange.

The Serengeti sits at the center of that economy, generating revenue that flows into conservation programs, local communities, airlines, hotels and park operations.

By improving year-round access while maintaining environmental safeguards, authorities say they aim to strengthen both conservation outcomes and the country’s tourism competitiveness in the years ahead.
