A super two is a type of highway that has two lanes, one in each direction, but is designed to handle higher traffic volumes and speeds than a typical two-lane road. It often includes features like wide shoulders, limited access points, and the ability to pass slower vehicles safely. A super two is usually used in areas where a full four-lane highway is not needed but where traffic flow needs to be more efficient and safer than on a regular two-lane road. It is often considered a cost-effective solution to improve road capacity without fully expanding to a larger highway.
