The road via Sagar is in bad shape.
The road via Nagpur is too long.
Roads approaching Jabalpur are terrible.
I would suggest a totally different route:
Raipur-Chilpi-Dindori-Umaria-Maihar-Rewa-Allahabad-Kanpur-Etawah-Agra-Delhi
I worked out distance (as per GMaps) as being around 150 kms more,
Why this route?
- NH7 towards Jabalpur from Nagpur is terrible all the way to Katni & Rewa
- Taking interior roads of MP, they are fantastic, although I have no current update on the road till Chilpi which is normally OK
- I have suggested an interior route from Chilpi all the way to join Maihar on NH7, all good roads but forest roads, 2 laned but safe, to be driven through by day
- The Bichia-Dindori-Umariya route has become very popular thanks to the perpetual bad condition of the NH7
- From Rewa, the road to Allahabad is good
- At Allahabad, you join the excellent 4-laned GQ route of NH2 all the way to Delhi.
Please bear in mind that fog is very dense this season through Central India, so ensure that you regulate your drive timings accordingly.
If you are still worried about going on this route, I would suggest you take the same route till Maihar, then go via Panna & Chhatarpur to Jhansi and then take the NS Corridor route to Delhi.
As of now, the NS Corridor work is still going on and the road between Laknadon & Sagar is in very bad shape.
