Build infrastructure that stands the test of time

Nepal’s floods damaged or destroyed essential infrastructure, including motorable bridges, roads, schools, healthcare facilities and homes. This disruption cut survivors off from hospitals, markets, goods and nearby settlements. Reconstruction therefore involves restoring both transport and basic public services.

The government built temporary access routes, installed Bailey bridges and made emergency repairs. It repaired the Krishnabhir section of the Prithvi Highway in 18 days. A timber bridge also reopened the road between Upper Manang and Chame within three weeks. In Nuwakot, a contractor built a 268-metre suspension bridge in one month.

These measures have improved travel and helped goods reach markets before Dashain and Tihar. However, many communities remain isolated, and some still depend on dangerous tuins. The article argues that emergency access must lead to carefully planned, resilient reconstruction rather than short-lived fixes.

The damage has reached a scale that makes reconstruction a national challenge. Government estimates put losses from the August 26 Bhotekoshi flash flood at approximately Rs400 billion. The late-September rains added an estimated Rs65.1 million in damage to the Kaligandaki Corridor.

The Bhotekoshi flood swept away 41 motorable bridges and damaged four others. It also washed away the road connecting Nepal to the northern border. Several sections of the Prithvi Highway were damaged, while the Kaligandaki Corridor suffered further losses from later rain. The Budhigandaki flood caused additional shock.

These figures cover more than physical structures. Damaged links disrupted healthcare access, markets, travel and the movement of essential goods. The scale requires lawmakers to prioritise affected roads and infrastructure in annual budgets, while governments coordinate long-term reconstruction instead of relying only on emergency repairs.

Bailey bridges are temporary, modular bridges that can be assembled quickly after a crossing is destroyed. Timber bridges use wood to create a short-term route over an obstacle. Tuins are hand-powered aerial cable crossings. All three provide ways to move people or goods when permanent infrastructure is unavailable.

Nepal used Bailey bridges and temporary access routes in flood-hit areas. A timber bridge reopened the road between Upper Manang and Chame within three weeks. In places where repairs were still impossible, people used tuins to cross dangerous gaps. These examples show how different solutions match different emergency conditions.

Their main value is speed. They restore access to hospitals, markets, schools and neighbouring settlements while stronger structures are planned. However, the article warns that temporary infrastructure may not survive heavy rain. Tuins are also dangerous, so they should not become a permanent substitute for safe, resilient roads and bridges.

Temporary infrastructure solves an immediate access problem, but it may not withstand the forces that caused the original destruction. A road can reach a community after emergency work yet fail again during heavy rainfall. When that happens, people lose dependable access precisely when conditions are most dangerous.

The article gives a clear contrast. Emergency repairs reopened Krishnabhir on the Prithvi Highway in 18 days, and a timber bridge restored Upper Manang’s connection within three weeks. These actions helped travel and goods movement before Dashain and Tihar. Yet some flood-hit communities remained cut off and had to use dangerous tuins.

The key issue is resilience, not simply speed. Roads and bridges need proper study, slope protection and safeguards against river erosion. Without those measures, repeated temporary repairs can trap communities in a cycle of rebuilding, renewed isolation and further hardship after each major rainfall.

Resilient transport infrastructure must be designed for the forces it will face. The article calls for adequate road studies, slope stabilisation and protection against river erosion. It also says bridges must reflect river hydrology, flood levels, debris loads and changing climatic conditions.

These factors shape whether a route remains usable during a disaster. Stable slopes reduce the risk of road sections failing, while erosion protection helps keep rivers from removing foundations or banks. Bridge designs that consider floodwater and debris are better prepared for the conditions that damaged Nepal’s recent infrastructure.

The immediate challenge is balancing urgent access with careful reconstruction. Temporary routes and emergency repairs remain necessary, but they cannot be the final answer. Roads and bridges should be rebuilt through coordinated, properly funded plans so communities are not repeatedly cut off whenever heavy rainfall, flooding or related hazards return.

Reconstruction involves Nepal’s federal, provincial and local governments. The article says these levels must coordinate their work rather than leave affected communities to manage overlapping jurisdictions. Coordination matters because roads, bridges, schools, hospitals and settlements are connected, even when separate governments handle them.

The need is visible in the response to the floods. Temporary routes and bridge repairs restored some travel, but many people remained cut off from hospitals, markets and neighbouring settlements. Children from Rasuwa began attending schools in Godawari, Lalitpur, while the article says safer schools should also be rebuilt in their home districts.

Coordination must be supported by budgets and long-term strategies. Lawmakers should prioritise flood-hit areas and damaged infrastructure in annual plans. Clear cooperation can reduce duplicated work, administrative delays and gaps between emergency access and permanent reconstruction, preventing affected communities from being stranded between jurisdictions.

Location and design must reflect the hazards around each site. River hydrology shows how water behaves, while flood levels indicate how high it may rise. Debris loads reveal what floodwater can carry. Slope stability matters because unstable ground can damage roads and buildings. Changing climate conditions make these assessments even more important.

The article applies this principle directly to bridges, roads and public buildings. Bridges should account for river hydrology, flood levels, debris and climate change. Roads need slope stabilisation and protection from river erosion. Schools, hospitals and settlements should be built in safer places rather than repeatedly exposed to the same dangers.

Nepal’s recent floods show why this matters. Bridges and roads were washed away, and communities lost access to essential services. Reconstruction should therefore use careful studies, sufficient funding and coordination. Otherwise, temporary infrastructure may fail again, leaving people trapped in recurring cycles of damage and repair.
