Sri Lanka can do a lot @ a fraction of the cost!
Provided the heat, emissions and dust managed well…by way of tree shaded cycling paths, showers at offices, promoting EVs and the likes.
And our Governments can do a lot, although they do nothing but worsening!
Just imagine making a cycling path along the Kelani valley railway line at least from Homagama to Fort.
There will be limited or no land acquisition needed and running along the scenic fields and canals….not only, across the colombo golf club as well.
The contribution to the economy by traffic reduction and health benefits will largely overweight even the limited investment.
