When floods struck in May 2023, the collapse of the Katonga Bridge and severe damage to the Lwera and Kalandazi swamp sections of the Kampala–Masaka highway plunged Uganda into a transport crisis. The highway, a vital artery connecting central Uganda to Masaka, Mbarara, and onward to Rwanda and the Democratic Republic of Congo, was cut off. Traffic was forced onto a 181‑kilometer diversion through Mpigi–Maddu–Ssembabule–Villa Maria, nearly 100 km longer than the original route. The economic and social consequences were immediate: traders lost money, travelers lost time, and communities around Katonga were isolated from schools, hospitals, and markets.
Recognizing the urgency, the Ministry of Works and Transport signed a UGX 191 billion Design and Build contract with China Communications Construction Company (CCCC) in January 2024. PROME Consultants Limited was engaged as supervising engineers. The project scope included temporary restoration of light traffic, construction of a steel jetty bridge to restore normal light and heavy traffic, and ultimately, a new permanent Katonga Bridge with 2.7 km of approach roads, alongside reconstruction of the Lwera (11.6 km) and Kalandazi (1.5 km) swamp sections.
Katonga Bridge: Gateway Restored
The Katonga Bridge was the centerpiece of the reconstruction effort. By August 2026, the new permanent structure was complete and open to traffic. The 2.7 km of approach roads were finished, and demolition of the old bridge was underway. The new bridge was designed with resilience in mind, ensuring it could withstand future floods and safeguard Uganda’s western corridor.
The contractor established a permanent camp at Kikoota Village, housing offices, accommodation, and a site clinic. Mobilization of equipment and personnel was efficient, though procurement of bitumen was slowed by global supply chain disruptions linked to Middle East conflicts. Financially, the project advanced steadily: 84.79% of the contract sum has been certified and 87% of physical works completed. Despite delays in Interim Payment Certificates (IPCs), which strained the contractor’s cash flow, Katonga is ready for formal takeover.
For residents and businesses, this milestone restores dignity and economic vitality. The bridge is not just concrete and steel—it is a promise fulfilled. Katonga’s completion demonstrates Uganda’s resilience in the face of disaster and highlights the importance of infrastructure in sustaining trade, tourism, and social services.
Kalandazi: Small Section, Big Impact
While Katonga Bridge captured headlines, the Kalandazi Swamp section—just 1.5 km long—quietly achieved remarkable progress. Floods in May 2023 devastated this stretch, paralyzing traffic and exposing the vulnerability of swamp crossings. The reconstruction project included construction of three box culverts, reconstruction of the swamp road, and ancillary works such as guardrails, signage, and landscaping.
By September 2026, the Kalandazi section was essentially complete. Culverts were in place, the road rebuilt, and finishing touches like grassing and landscaping were underway. Though small in scale, this section is vital. It ensures continuity of the Kampala–Masaka highway, preventing bottlenecks and guaranteeing safe passage for vehicles. For local communities, it restores access to markets, schools, and health facilities.
The project’s success here reflects effective coordination between the Ministry of Works and Transport, CCCC, and PROME Consultants. Despite challenges with delayed IPC payments and rising costs of bitumen, the Kalandazi works were prioritized and delivered on time. The contractor’s mobilization of personnel and equipment ensured efficiency, while the establishment of an asphalt plant near the site supported operations.
Kalandazi’s completion underscores the importance of attention to detail in infrastructure projects. Even short sections can have outsized impacts on connectivity and livelihoods. For travelers, the smooth passage through this swamp is a reminder that progress is not always measured in kilometers but in reliability.
Lwera: The Remaining Frontier
The Lwera Swamp section, stretching 11.6 km, remains the most challenging part of the reconstruction project. Flood damage in 2023 left this corridor vulnerable, and while significant progress has been made, completion hinges on resolving bitumen supply issues. By August 2026, all culverts—21 box and 13 pipe—were completed. Fill and pavement layers reached the road base level, and construction of Dense Bitumen Macadam (DBM) from Km 0+000 to Km 3+000 was finished. To protect exposed layers, a temporary single surface treatment was applied from Km 3+000 to Km 11+600.
The asphalt plant near Kalandazi is operational, but procurement of bitumen has been disrupted by global conflicts. This has slowed progress, threatening timely completion. Financially, the project is strong, with 87% physical progress overall, but the Lwera section remains the bottleneck. Without resolution of bitumen supply, the final asphalt layers (DBM and AC‑14) can not be completed.
Despite these challenges, the project demonstrates resilience. Temporary measures ensure traffic can flow, preventing complete paralysis. The government’s commitment, backed by UGX 191 billion in funding, remains firm. The contractor has mobilized resources, and supervision by PROME Consultants ensures quality control. Yet, the lesson is clear: infrastructure projects are vulnerable to global supply chains, and diversification of material sources is essential.
For Uganda, the Lwera section is more than a technical challenge—it is a test of endurance. Once completed, the Kampala–Masaka highway will be fully restored, reconnecting central Uganda to the west and beyond. Until then, Lwera remains the frontier of progress, a reminder that resilience requires persistence.
Challenges and Lessons
The project has faced two major challenges: delayed payment of IPCs and scarcity of bitumen due to global supply disruptions. Delayed payments constrained the contractor’s cash flow, particularly after the expiry of the pre‑financing period in January 2025. Rising costs of bitumen and fuel created financial pressure and procurement delays. These challenges highlight the importance of timely financial management and diversification of material sources in large infrastructure projects.
A Road to Renewal
The Katonga–Lwera–Kalandazi reconstruction project is more than an engineering effort—it is a national renewal. Katonga Bridge is complete, Kalandazi is finished, and Lwera is progressing despite challenges. Together, these sections restore Uganda’s lifeline to the west, reconnecting communities, revitalizing trade, and strengthening resilience against future disasters.
The project demonstrates Uganda’s ability to respond to crisis with determination and innovation. It underscores the importance of infrastructure in economic growth and social well‑being. As the final layers of Lwera are completed, the Kampala–Masaka highway will once again stand as a symbol of connectivity, resilience, and progress.
