Torrential rainfall and landslides in different parts of Kerala have taken a huge toll on road connectivity in the state, stranding several people in different districts. Many who have evacuated from flood-hit residences, however, are unable to move to other districts with roads block, train lines disrupted and air services from Kochi suspended until August 26.

TNM looks at some key routes and areas that have been cut off due to flooding. The worst-hit districts are Kozhikode, Ernakulam, Thiruvananthapuram, Palakkad, Thrissur, Pathanamithitta and Idukki, with access blocked along many routes due to flooding or landslides.


All National Highways including between Ernakulam and Thrissur have been facing road blocks due to waterlogging. The NH 66 from Edapally to Thrissur via North Paravur, Kodungallur and Guruvayur is currently blocked at Chendamangalam, North Paravur and Varappuzha.

The National Highway - NH 544 - from Edapally in Kochi to Thrissur via Aluva and Chalakudy is blocked at several places such as Thotakaatukkara and Ambattukaavu due to waterlogging. Aluva and Chalakudy are reeling under floods with the Periyar in Aluva and Chalakudy river flowing in spate.

The diversion from Angamaly to Perumbavur to Kalady and then to Aluva have also been blocked due to waterlogging in areas such as Kelamattam and Vallam and Kalady.

From Thrissur, the NH 47 runs via Manuthy to Palakkad. However due to intense rains over the past few days and landslides at Kuthiran Highway tunnel on NH 544, the route is completely cut-off with traffic being blocked.

However, the areas on the route such as Viyur in Thrissur have been inundated due to heavy rainfall. Further the route also passes the Bharathapuzha River, which is in spate following the opening of the shutters of the Malampuzha dam, leading to traffic regulations in the area. 


In Idukki, one of the worst hit districts of Kerala, the Cheruthoni-Thodupuzha road to Ernakulam remains inaccessible with multiple blocks in the area.
