Two more viaduct bridges are being constructed on the Parwanoo-Solan section of the National Highway-5 (NH), the four-laning of which was completed in June 2021. One such bridge has already been constructed on the 39-km stretch of the Parwanoo-Solan road.
All three bridges were not conceived in the detailed project report (DPR) prepared for this section earlier. Since these sites comprise of sinking zones, where retaining walls can’t withstand the repeated slides, it was decided to opt for these structures to provide stability.
One bridge is being built near Patta Mor between Dharampur and Kumarhatti and the other one near Saproon in Solan city.
