In recent years a network of highways has been under construction across Sri Lanka.  Although with a relatively slow speed limit of 100 KPH (62MPH) that is enforced by average speed measurement between toll booths (and printed on your receipt) as well as the occasional traffic cop with a radar gun, the impact on journey time and smoothness is profound.

Quite a contrast too to the old main roads as you can see in these two images take during our drive from Tangalle to Udawalawe.
