Given Data:

west java

the flag must be the road name or place name

Lets start the party:

every details matter tried to elicit any small detail, for 5–6 minutes, from the above image and haven’t found anything at last pointed out GOOGLE watermark ,which one usually saw on google map’s street view, thus got the idea that the picture is screenshot from it.

reversed image the picture using Reverse Image Search extension, didn’t find anything.

started searching “west java roads” images and found famous road infrastructure results, but nothing which gave any idea about the given picture.

after surfing for about 10–20 minutes, think about re-evaluating the approach and again started to pinpoint small details in the given picture and found that there is a bridge which is horizontal to the overpass, usually such bridges are used by subway/train.

typed “west jawa train bridge” and started reviewing images and found

and from the “dreamsite” one

read the description of the image “High Speed rail bridge” googled this and found that this High Speed Train project connecting jakarta and bandung which is about 143 km and is still under construction.

but this still isnt enough to verify any analogy between them thus its still unknown

started searching about HSR and found the whole story about the ongoing project on Future Southeast Asia where found the project map integration on google maps too

the last station mentioned in the map was “Stasiun Kereta Cepat Tegalluar” open the exact location in google maps . switch the layer to satellite one and found that there are rectangular structures

try Google Street View if there is more info by any chance

there wasn’t was any any clear view near the station but these structures were parallels to the road thus tried to get the view from a point near to the road and it was verified that these were bridge support pillars.

followed these structures on google map’s satellite view and found that these were alongside to the road to a certain point after which there was a bridge too

now reconstruct the given picture memory in mind by visualizing that there must be certain location in the map where these structures must overlaps two roads parallel to others roads too

search and found that there were several overpasses on the roads parallel to the bridge out of them one was complex overpass tried to check the availability for street view

used street view to a point near the overpass

its easy to use Google Street View on mobile rather on computer because of touch gestures control open this location on mobile and do a little tour

and found the exact location.

FLAG === KCTF{padaleunyi_toll road_west_java}
