I would like to submit that the intersection of JhongJhen Rd & HuanHe Rd (ShuiYuan Highway entrance) during morning rush-hour is the worst bottleneck in Taipei.
At this intersection there are 5 northbound lanes on HuanHe (1 is the ramp from the Shoulang Bridge from JhongYongHe, 2 are the northbound thru lanes and 2 more are the right-turn only lanes, from which cars don’t turn right during morning rush hour, but ignore the arrows and go straight) merging with 2 right-turn lanes off JhongJhen Rd onto HuanHe (which is in fact only 1 lane, but cars from the middle lane push into the right-turn lane) all fighting for the 3 northbound lanes on ShuiYuan Highway. That’s 7 lanes merging into 3. At the top of the hill, those 3 lanes have to merge into just 2 to make room for another on-ramp from JingMei. What an absolute clusterf*ck.
Morning rush hour there has gotten progressively worse as the build-up in Xinbei continues. There was a noticeable increase in traffic when they finished the Ankeng Bridge, which dumps even more cars onto HuanHe than were already there. I shudder to think what it’s going to be like when MeiHe City is finished. I think that’s 2000 more residential units in the area.
I have a bird’s eye view of this intersection from my apartment. Between 7-9am, cars are backed up as far as I can see, across both bridges and down HuanHe.
Any other candidates?
