<p>The objective of the paper is to illustrate the challenges and strategies of rebuilding infrastructure on Nias Island after the 2005 earthquake, focusing on trailbridge construction, local capacity-building efforts and the integration of indigenous knowledge and modern engineering practices.</p><p> The Nias Islands, remote with a unique indigenous culture, suffered severe damage in the 2005 earthquake. The ILO helped rebuild infrastructure, including 72 river crossings and 250 km of feeder roads or motorbike trails. Frequent seismic activity, high rainfall and unstable soils from uplifted seabed material make constructing of stable bridge foundations on Nias Island highly challenging. Traditionally Nias relied on human transport. In recent years motorbikes and pedicabs have now become an increasingly popular mode of transport. The project's cross-drainage structures include i) culverts, ii) boardwalks, iii) drifts, iv) palm log bridges, v) I-beam composite bridges, vi) steel truss bridges, vii) suspended bridges, and viii) suspension bridges. For structure types (i) to (v) the project developed its own designs while for the larger bridge categories of (vi) to (viii) Nepal Trail Bridge Design Standards were applied. The project addressed skill shortages by training local staff, contractors and community groups through a structured training programme and a six-month apprenticeship. Most graduates became site supervisors, securing jobs in construction firms, public works, or NGOs. </p><p> The project successfully rebuilt critical infrastructure, overcame challenging environmental conditions, and addressed skill shortages through comprehensive training, ultimately improving connectivity, creating employment opportunities, and enhancing the livelihoods of the involved communities.</p>
