NHAI wants the half-finished viaduct and rail over bridge at km 117 on the Solan to Kaithlighat stretch of NH-05 completed, and the Solan Kaithlighat viaduct tender closes on 16 September 2026.
What is left to build
This is balance work, not a fresh start. The approach and the structure of a viaduct cum ROB at km 117 in the Solan to Kaithlighat section of NH-05 in Himachal Pradesh have been part built and NHAI’s Shimla regional office is now bidding out what remains. The estimate is ₹53.00 crore, the reference is 11011/95/Tender/26-27/09 and the form of contract is item rate. NH-05 is the Kalka to Shimla artery, so the site sits on a working hill highway carrying traffic while the work goes on.
Who should bid
Balance-work packages reward contractors who read the site before they read the BOQ. Someone else’s partly built substructure, whatever its condition, is what you inherit, and hill alignments rarely match the drawings exactly. Earnest money is ₹1,06,00,000, which is two per cent of the estimate, and the tender fee is ₹50,000. At ₹53 crore this is within reach of a good regional bridge contractor rather than needing a national player. If you already hold work on the Kalka to Shimla corridor, mobilisation is close to free.
What you will run on site
Viaduct and ROB work in the hills is crane-led. Expect a crawler or hydraulic crane with real reach for girder and segment placement, a piling rig or rotary drilling rig if the remaining foundations call for it, and a batching plant with transit mixers and a concrete pump for pier caps, deck and approach slabs. The approach embankment brings back excavators, tippers, a motor grader and soil compactors, with breakers where rock shows up. Traffic on a live national highway means barricading, night pours and a lot of standing time, so price the crane on calendar days rather than working days.

Location
Km 117, Solan to Kaithlighat section of NH-05, Himachal Pradesh
The viaduct cum ROB at km 117 is already part built. The winning bidder completes the remaining approach and structure rather than starting from the ground up, so a site visit matters more here than on a fresh package.
What is the earnest money?
₹1,06,00,000, exactly two per cent of the ₹53.00 crore estimate. The tender fee is ₹50,000, which is high relative to the contract size, so factor it in.
Where exactly is the site?
Km 117 of NH-05 in the Solan to Kaithlighat section, Himachal Pradesh. NHAI’s Shimla regional office is the inviting authority and bids are opened there.
Will traffic keep running during construction?
The NIT does not state a closure, and NH-05 is a live artery between Kalka and Shimla, so plan for staged working under traffic. Confirm the traffic management conditions in the tender document before you price.
