It is good news that a bus will run between the three countries of Bangladesh, India and Nepal. A trial run was done recently when a bus started from Dhaka and went to Siliguri in India and then to Kathmandu in Nepal carrying 45 delegates from these countries.
The distance between Dhaka and Kathmandu is not very long and it does not take much time to get from one place to another by road.
Since there are no buses running currently from Dhaka to Kathmandu, Bangladeshis (also Nepalese) need to travel by air which can be quite costly. Once the planned bus service is fully functional, it should substantially reduce the travelling cost for citizens of all three countries, especially those who travel frequently.
I hope the authorities will launch this service as soon as possible once the vetting phase is complete.
