I regularly drive between Mumbai and Belgaum, but haven't been updating here due to many commitments. Some updates :-
1. The journey time between Mumbai and Belgaum had gone up by straight 1 hour since last 4-5 months due to full fledged road widening work from 4 to 6 lanes from Satara to Belgaum and the ever traffic snarl prone Mumbai--Pune Expressway. Pune bypass was another pain many a times. Now add another 1 hour in these rains.
2. Roads remained mostly good all through but it is the construction work causing delays. Understandable. Sankeshwar--Hattargi is in its worst shape since last 2 years ever since Kolhapur--Belgaum 4 laning got completed in 2004. Worst doesn't mean huge potholes but extremely rough surface, bouncy ride due to huge bumps scattered all over. This road used to be impeccably supersmooth all the way from Kolhapur to Belgaum.
3. Work on Missing link of Mumbai--Pune Expressway is happening at a good pace but may open up for traffic only in second quarter of 2024. Can say the same for new twin tunnels/new link at Khambatki ghat between Pune and Satara. Both these are really game changer projects on NH4 in Maharashtra. Direct saving of 1 hour !! But I will surely miss driving on Khandala ghat and Khambatki ghat. Okay, think better to miss Khandala ghat

but Khambatki ghat used to be peaceful and moving.
4. Satara--Kolhapur--Kagal 6 laning work is taken up by Nagpur, MH based DP Jain infrastructure. His sample new 6 lane bridges have awesome smooth surface. His work also looks fast and neat. Not sure who is doing 6 laning of Kagal--Belgaum sector but the work there is fast paced as well. However, 6 laning of Kagal--Belgaum was absolutely unnecessary given the low volume of traffic in Karnataka. The good old 4 lane highway built by Punj Lloyd ( with dedicated service lanes) was of top quality and enough for the given traffic. I don't foresee traffic to increase here to a level that a 6 lane was necessary for the next 20 years. Around 50000 good trees along the highway were felled. Those trees were planted as young saplings 20 years ago when 4 laning was under construction and had grown up to full extent only since last 7 years or so. Now chopped down, what an absolutely unnecessary project !! Satara--Kagal was brimming with heavy traffic always, so a 6 lane there with service roads was inevitable but the final stretch to Belgaum was well served by the 4 lane road. Anyways, both these projects seem to get completed by early 2025.
5. The Chandni Chowk interchange project at Pune ( NH4 bypass) is the most complex interchange in our country for sure

I used it once to get onto the road towards Mulshi and got lost two times, somehow succeeded the third time. Didn't really try to break my head to understand it for now atleast. By the way, that one final flyover on main NH4 that was pending is now complete and will be thrown open to traffic soon, August 1st is the tentative date of inauguration.
6. I was scheduled to drive Mumbai to Belgaum tomorrow but postponed because of heavy rains lashing all the way from Mumbai to Belgaum and a landslide that occurred on Mumbai--Pune Expressway about 3 hours ago ( Mumbai bound carriageway is totally shut). NH4 highway at Kolhapur is currently open but Panchganga river is just about 5 feet short of breaching the danger mark and thereby flooding Kolhapur city, NH4 highway and all the nearby regions. Apparently if rains continue in Kolhapur for the next 48 hours, highway is at risk of closing down. Hope that doesn't happen. Will update monsoon road conditions after I complete my drive on Tuesday or Wednesday.
7. Had driven to Hubli in between, finally the Hubli--Dharwad 31 kms section has woken up from years of deep sleep to become a 6 lane. Expected to finish in second half of 2025.
8. @Dr. AD the "Viraj junction" food mall at Kognoli toll in Karnataka limits ( Bangalore direction) is a proper food court/mall after the ones on Mumbai--Pune expressway and also Khed Shivapur toll, Pune between Satara--Pune. Probably the first and only food mall in KA part of NH4 all the way till Bangalore, unless anything new has come up outside Bangalore limits of late.
9.The "Maharastrian food flavours" food mall at Pune is a proper food mall too and highly recommended for trying local dishes. I stop here frequently on my drives, great place and reasonable prices. There is one more proper food mall a few kms ahead but haven't been there yet.
10. What's the status of Tumkur-- Nelamangala section of NH4 ?? Badly needs 6 lanes from its current 4 lanes.
