The Construction of Pitigoda Bridge
The Pitigoda Bridge project is a remarkable example of engineering for social impact, carried out through a collaborative effort between Engineers Without Borders – Sri Lanka (EWB-SL) and Engineers Without Borders – Karlsruhe Institute of Technology (EWB KIT), Germany. The project involved the construction of a pedestrian suspension bridge across the Ma Oya River in Pitigoda, a remote agricultural village nestled in the Randenigala Valley, about 12 km from Hunnasgiriya in Sri Lanka’s Central Province.
Prior to the construction of the bridge, Pitigoda was severely isolated. The village, home to nearly 350 residents in around 70 families, relied heavily on agriculture—mainly rice and tobacco cultivation—on lands situated on both sides of the river. However, during the rainy season, frequent flooding caused the river to rise by as much as 3 to 4 meters, making it extremely dangerous or even impossible to cross. This cut off access to schools, healthcare services, and nearby towns, and made it difficult for farmers to reach their fields or transport their produce to market. Children, the elderly, and people with disabilities were particularly at risk during flood periods.
The suspension bridge was designed to provide a safe, reliable, and flood-resilient river crossing for the community. The entire project—from design to construction—was led by volunteer students from EWB KIT, with support and guidance from academic staff and final-year students of the Department of Civil Engineering at the University of Peradeniya. The bridge was fully funded through donations, with all contributors offering their time, resources, and skills voluntarily.
Beyond its practical function, the bridge became a symbol of hope and connection for the village. Its construction attracted the attention of local government authorities, who subsequently undertook the improvement of the rural road linking Pitigoda to Hunnasgiriya, greatly enhancing the village’s overall accessibility.
Together, the bridge and road development projects brought about significant improvements in education, healthcare access, economic mobility, and social well-being. The increased connectivity has encouraged teacher placements in local schools, improved healthcare delivery, and strengthened the community’s ability to participate in regional trade and development. It has also made the village a more attractive place for settlement and growth.
Today, the Pitigoda Bridge stands as a lasting achievement, maintained by EWB-SL members and cherished by the local community. The project not only transformed Pitigoda but also served as an inspiring reminder of what young engineers can achieve through collaboration, compassion, and commitment to sustainable development. It continues to motivate EWB teams both in Sri Lanka and around the world to harness their skills in service of humanity.
Project Details: Pitigoda Suspension Bridge
• Project Type: Pedestrian Suspension Bridge
• Location: Pitigoda Village, near Hunnasgiriya, Central Province, Sri Lanka
• Span Length: 43 meters
• Walkway Width: 1 meter
• Bridge Deck Material: Tropical hardwood, pressure-impregnated
• Total Weight of Bridge: Approximately 5 metric tons
Structural Components
Support Structure:• Two steel pylons, each 7 meters high, support the bridge.
• The pylons are constructed using recycled H-profile steel roof beams from a former warehouse.
• Each pylon forms part of a trapezoidal double mast, secured in a foundation-mounted quiver.
Foundations:
• Two socket foundations (each 10 m³) support the pylons.
• Two additional, slightly larger anchor block foundations are used for the back anchorage of the main suspension cables.
Suspension System
Main Suspension Cables:• Diameter: 20 mm
• Anchored at both ends into reinforced back anchorage blocks.
Hanger Cables:
• Diameter: 10 mm
• Includes both vertical and side hanger cables for even load distribution.
Total Cable Installed: 624 meters of high-strength steel cable
Walkway and Access
Decking:• Constructed from pressure-treated tropical wood, ensuring durability in outdoor conditions.
Access Ramps:
• At both ends of the bridge, brick masonry ramps gently lead from the ground to the bridge deck, ensuring easy and inclusive access for pedestrians of all ages.
