July 14, 20215 yr Does anybody have any experience or photos or videos of the tunnel during heavy rain? Does it flood? If not, where do they pump the water to?
July 15, 20215 yr It would take several meters of flooding at the lower parts of Sukhumvit before this tunnel could flood. It only catches the direct rain at the entrances. For this there's pumps at Pattaya Klang intersection.

And of course you will see flooding particularly to the north of the underpass when we get heavy rain.
July 16, 20215 yr Not seen flood water there , i think its because they sweep the road through the tunnel that keeps the drain covers clear ... no garbage covering the drains no floods
July 16, 20215 yr If I recall correctly, years back when the tunnel was new they had flooding/pump problems but since then they replaced the pumps and I don't remember hearing of flooding recently.

Never known the tunnel itself to flood since it was opened.

This is where the problem is - not long ago the traffic going south into the tunnel and upto the Klang intersection was at a crawl as the 4 lanes basically became 1 with deep water to the inside and abandoned cars. Traffic coming north out of the tunnel was slow to get through the flooding just after the tunnel exit.

July 16, 20215 yr It might be an underpass but it is higher than most surrounding roads ie from the north you drive up a slope travelling south so v unlikely to flood
July 16, 20215 yr The only time it flooded was when it was being built as its on top if a slight hill it would be almost impossible to flood now that both ends are open.
July 16, 20215 yr At least they got it right this time. Don’t knock them down when they finally get something right, otherwise we may never see it again. Let’s just look at beach road flooding or the sand fiasco. Give praise when it’s due.
