Lungtenzampa motorway bridge should be replaced with a beautifully designed arch way pedestrian bridge. Let Lungtenzampa revert to historic walks of romance.
However the feud between Tashi group and Thimphu Thromde over Lungtenzampa bridge ends, traffic congestion will still choke this area.
The Thromde and Tashi group can keep fighting but not over Lungtenzampa bridge please. Thimphu city needs far more usefully convenient bridge and road to clear the traffic congestion.
So forget Lungtenzampa motorway bridge. Make a pedestrian crossover plaza.
Construct a twin bridge along the lower Chubachu bridge presently under construction. And expand the road from Dechen Zam to Simtokha to 4 way traffic to cater to traffic towards East from Thimphu and to compliment the present Express way for South & West traffic from Thimphu.
Build a flyover road over the Chuba stream from upper Motithang ( where the present road forks one towards BBS tower and the other down towards Zilukha ) all the way down to the twin Chubachu bridge. Connect all internal roads to this flyover road and to the present road from upper Chubachu round about to the new bridge presently under construction. The flyover road is suggested because there is no other land space to build the required road. The flyover road and twin bridge will definitely ease congestion within Thimphu core area as well as reduce traffice pressure on the present Expressway.
