Parwanoo–Solan NH-5 Four-Laning Cost Overrun & Flyover Collapse

Blunderlust rating★★★★★ 3.6 / 5 · 334 reviews⌖ Parwanoo-Solan-Kaithlighat section of NH-5 (Kalka-Shimla highway), SolanEntry #01 in Solan

On record

The four-laning of a 39km NH-5 stretch, awarded with a 30-month deadline, took over five years to substantially finish and required extensive extra slope-stabilisation after the original design proved inadequate. In August 2022, a large flyover portion on this same stretch collapsed during heavy rain near Solan.

The official record states: "NHAI/contractor cited inadequate original slope stabilisation (1.5-3m walls on 20-30m excavated hill slopes); the 2022 collapse was attributed to heavy rains and landslides."

“Thirty months became five years, ₹748 crore became a thousand, and then the flyover fell down anyway.”— Blunderlust Editorial Desk

Visitor reviews Satire

“Thirty-nine kilometres of the Kalka-Shimla road took five years and a thousand crore, and then a flyover span came down in the rain.”
TR T. Rao · Solan★★★★★
“They cut twenty-five metres into the hillside and held it back with a three-metre wall. The hill disagreed.”
LM L. Menon · Solan★★★★★
“Drove up to Solan past slope-stabilisation work that was added after the design turned out not to include the slopes.”
DG D. Ghosh · Solan★★★★★
