I did some research on the ways to get around within Bhutan. Taxis seem to be the most popular option for any tourists as they will know how to best deal with the ever-changing environment. The prices are quite high as tourism is still quite rare. Foreigners can obtain a two week driving license, but the process is a little complicated. Bhutan only has four airports total with air travel being limited. Currently there is no railway in Bhutan, but the Indian government has made an effort with the Bhutanese government to create a linked railway.
