The calicut route does not make any sense - because it ultimately lands u up in Thrissur, no matter what and the Thrissur-Cochin stretch has to be done(NH 17 is an option, though). For avoiding Walayar-Palghat-Thrissur stretch(70-80kms), you travel about 100 more KMS???? Till Coimbatore, the roads are Ok in TN, only the traffic is more.
My suggestion is to take the normal route and be prepared to drive slowly and carefully in the Walayar Stretch, take your time...
Unless you want to drive 100 more kms/enjoy scenic roads/ghats.
Now you decide. |
