Chaeng Watthana Road, or Highway No. 304, is notorious for being struck by flash floods. Within a matter of minutes heavy rain can turn the road into something verging on a small canal, which usually takes at least three hours to drain.
The road runs through Pak Kret district of Nonthaburi and the Bang Khen and Laksi districts of Bangkok.
After years of complaints from residents, the Ministry of Transport has finally decided to try and solve the problem once and for all.
