People preferred longer alternative routes when traveling through the Kuthiran area mainly due to the unreliability of the Kuthiran Tunnel. According to the Wikipedia page on the Kuthiran Tunnel, individuals who were aware of the tunnel's issues used to opt for alternative longer routes to ensure a reliable journey time [1]. The tunnel was known for its traffic congestion, especially with trucks, which could significantly delay travel [2]. Additionally, the potential for accidents and the subsequent traffic jams within the tunnel made the longer routes more appealing despite their distance [1]. Images of the Kuthiran Tunnel and its surroundings can be found in various sources, illustrating the area's topography and the tunnel's entrance [3][4][5][6][7][8][9][10]. These factors combined led travelers to choose longer routes to avoid the uncertainties associated with the tunnel, ensuring a more predictable travel experience.
