Anyone wishing to go from Miri to Brunei must use the Asian Bridge across the Baram river. This bridge was "privatised" to build and then collect toll. It must be due to the low traffic flow that the charges are so high. Just see... I think those using Penang bridge must feel relief now...
... there is opening hours to this bridge! If you miss the closing time, you have to sleep in the car during the last 20KM of your journey into the town. My friends from W.M. was stuck at this point and spend a night here!
See... no kidding!
By the way, I was stuck at the immigration on Brunei side once and had to spend a night on the road side feeding mosquitoes! The gate close at 10:00PM sharp! So be early.
