About 80% of the population live in rural
areas or small towns with minimal or no nearby access to roads.
Trails and mule tracks remain important transport routes. Access
to input and output markets and to services get interrupted
during monsoon rains as river crossings become dangerous or
impossible, thus constraining the livelihood sources of rural
TRAIL BRIDGE SUB-SECTOR PROJECT (TBSSP)
The Trail Bridge Sub-Sector Project
capitalizes on more than 30 years of experience with bridge
building in Nepal. Two types of bridges emerged: the Long Span
Trail Bridge (LSTB) and the Short Span Trail Bridge (SSTB). The
recent Trail Bridge Strategy delineates which type is to be
applied when. The Strategy along with 16 detailed manuals on
norms, standards and procedures have enabled the
decentralization of trail bridge building to DDCs. This has
opened entry to the World Bank and Asian Development Bank for
supporting bridge building. TBSSP’s role is gradually being
transformed from facilitation to monitoring/inspection of the
entire sub-sector, ensuring that resources are being effectively
Thirty-one Educational Institutes (EIs) (2
universities, 5 colleges and 24 CTEVT-schools) have integrated
the aforementioned Strategy / manuals in their curricula.
These EIs are training the technical staff of all 75 DDCs (dedicated
courses) plus their own regular intake (regular curriculum)
DDCs implement LSTB bridges through the private sector
(consultants and contractors) and SSTB bridges through NGOs and
The Trail Bridge Section of DoLIDAR/MoLD is
responsible for enforcement of the Trail Bridge Strategy /
manuals and coordinating donor support hence ensuring a coherent
Approximately 2,200 bridges have been built
with the Swiss support until mid July 2006.
Approximately 140-180 new trail bridges
are constructed every year with project support.
Bridges fallen in disrepair undergo
Bridges built before the development of
norms and standards are gradually being rehabilitated.
Every SSTB and LSTB bridge provides
improved and safe access to an average of about 150 and 400
daily users, respectively; an average of about 3,000 people
live in the direct zone of influence of a bridge.
Expertise from Nepal on trail bridge
building has been provided through training and technical
assistance to other countries such as Tanzania, Ethiopia and
Various actors come gradually together under
a sector-wide approach:
The World Bank and Asian Development Bank
provide funds to DDCs which facilitate bridge building.
Government of Nepal (GoN) provides block
and sector grants to DDC for trail bridges.
DDCs delegate LSTB to the private sector
and SSTB to NGOs/ communities.
EIs provide training to technical staff.
NGOs provide training to communities.
