The absence of arterial roads to divert traffic from Solan to Kaithlighat during traffic jams worsens the situation. It being a busy highway, vehicles queue up within no time whenever debris from the excavated hill falls on the road. Three or four spots are vulnerable to landslides owing to the fragile strata.
A long traffic jam was visible on Sunday at Mansar Salogra village on the Solan-Kandaghat section of the highway disrupting traffic for nearly an hour.
Residents rued that arterial routes should have been worked out before the four-laning work had begun. This would have helped in diverting traffic.
