Auki-Fouia Road in Malaita Province, Solomon Islands

These bridges on the Auki–Fouia Road were replaced to deliver safer, wider, and climate‑resilient infrastructure for communities in Malaita Province.

Bio 1 & 2

The project replaced two deteriorated single‑span bridges north of Auki, addressing safety concerns.

Both bridges replaced the deteriorated structures, improving the previous narrow widths, unsafe surfaces, and the lack of pedestrian access.

Key project points

Resilient
Seismic‑ready E‑grade rebar and integral construction ensure the bridges withstand natural disasters and harsh environmental conditions.

Safe
Wider lanes, a dedicated pedestrian path, and non‑slip surfaces significantly reduce risks for vehicles, passengers, and children.

Efficient
Lightweight components and in‑situ pouring allowed rapid installation by a skilled five‑person crew using smaller cranes.

Durable
Magnelis® steel provides exceptional corrosion protection, delivering a low‑maintenance structure built for long‑term performance.

Community-Focused
Local labor, improved access to healthcare and education, and safer travel routes directly support Malaita’s social and economic growth.

The location

The Bio1 and Bio2 bridges sit along the Auki–Fouia Road in Malaita Province, approximately 14 km north of Auki and near the village of Buma.

‍

The region experiences heavy rainfall, slippery road conditions, and river environments that demand resilient, safe infrastructure. Transport routes here are vital for connecting rural communities to services, markets, and schools.

‍

Challenges

The original bridges were narrow, structurally deteriorated, and lacked safety rails and pedestrian access, creating hazardous conditions for vehicles and children.

‍

During wet periods, the bridge surfaces became dangerously slippery, increasing the risk of accidents. Transporting materials to Auki also required coordinated shipping, barge transfer, and careful handling due to the remote island environment.

How we helped

InQuik’s top‑down construction method protected the waterway, keeping it clean and safe for local use throughout the build.

‍

Lightweight components and flexible installation allowed the contractor to use smaller cranes and local labor, improving efficiency and community involvement. The new integral bridges now provide long‑term safety, reliable connectivity, and disaster‑resilient infrastructure for Malaita residents
