Dhaka is clearly more clean than say 5 years ago. Roadside old, mega dustbin with overflowing garbage are now mostly gone.City corporation has taken initiative to collect garbage door to door.They also set up 15,000 small trashcan throughout the city.

Another thing is, now much emphasize are given to build and expand the footpath where ever is possible. I see a lot of footpath are being built now in roads previously which was just a road with unpaved, muddy sidewalk, during monsoon that was horrible to walk.But many narrow 'Gulli' road condition is not yet improved.Major factor being lack of space.Some 'gulli' roads are now being build on concrete to lengthen it's longevity which was not the case earlier.For some cases, construction companies which build such narrow road, being held liable to ensure that no pothole emerges within 1 year before payment.So better quality of works.
Currently Abdullahpur-Chourasta(Gazipur) road perhaps the most horrible within greater Dhaka. No improvement or repair done to this road for few years as it is left for BRT project which got delayed for several years.
