Has anyone actually done the 2.5-hour drive to Dehradun on the new expressway yet?

The commute from Delhi to the Himalayan foothills just got a massive overhaul, cutting travel time from 8 hours down to roughly 2.5. It is a fully access-controlled route with a 100 km/h limit, though they have strictly banned two-wheelers and tractors to keep the traffic flow safe. The standout feature is the 12km elevated wildlife corridor over Rajaji Tiger Reserve, allowing you to drive above the forest canopy while animals move below. If you're planning a trip, be aware that fuel stations are still scarce on the main stretch and the full toll for a car is around ₹430.
Do you think this shortcut will make spontaneous weekend trips to Mussoorie actually feasible, or will the surge in crowds just create a new kind of bottleneck?
I found a detailed breakdown here link in comments if anyone needs the specific toll rates or the route map.
