decided to pay a visit to the smart while it's free. so off i went since it's only a short drive from where i stay.the toll plaza is so messy. and there were workers sitting in the booth, opening the barrier for everyone and no toll was collected. rehearsing for the real thing?
moving on, i thought we can see the rounded shape in the rock left by the TBMs at the entrances, but they were rectangular. only inside can one see the rounded ceiling.few minutes down the bumpy road and it ends at the city centre. not bad, this tube cuts traveling time.
now let's go home the way we came.it was a short and fun outing. never driven through a tunnel this long before. wonder if that thing i saw along the way was one of the floodgates. should be, i could not stop to find out.
