East–West Corridor Upgrading, Section 4
Widening and reconstruction of a 21 km highway section carrying continuous freight traffic, including cross-drainage replacement and a reconstructed urban section through two market towns.
Roads, bridges and access infrastructure built under live traffic and seasonal constraints.
Transport assets are built while people are using them. Traffic management, diversion quality and community notification are part of the engineering, not an afterthought bolted on at mobilisation.
In hill terrain the controlling risks are slope stability, drainage and monsoon access. We plan the season's work around those, and build drainage before it is needed rather than after it fails.
Staged closures, signed diversions, trained flaggers and night-working windows agreed with the road authority.
Cross-drainage, catch drains and slope protection installed ahead of the wet season, not retrofitted after damage.
Bridges, culverts and retaining structures sequenced with the road corridor so the pavement is not opened twice.
Corridor earthworks, pavement construction and drainage delivered under live-traffic conditions.
ViewRiver crossings, retaining structures and heavy civil works engineered for the site's real conditions.
ViewCondition assessment, structural repair and asset renewal that extend service life.

A 180-metre, four-span river crossing replacing a seasonal causeway that closed the corridor for up to eleven weeks each monsoon. Substructure was built inside a single low-flow window using staged cofferdams.
Reinstatement of 3.2 km of hill road after monsoon slope failure, combining emergency access restoration with permanent stabilisation and drainage.
