julian, that tunnel itself IS the emergency exist (for flash flood), so you don't need an emergency exist for an emergency exist itself. LOL.
okay, I just went today, better try it before Gov start collect toll fee, tried the Sungai Besi -> Jln Tun Razak tunnel, most likely the middle deck.
Many of us did complain about the cement uneven surface, from my point of view, it's there because
1. Uneven surface so that you won't speed 99 in the tunnel, I found it okay if you constantly travel in 60KM/H. So it's for safety reason.
2. The smart tunnel middle deck has the lowest height in overall if I'm not mistaken, you just can't bring the big machine (those I saw in PLUS highway are big and HUGE) in to do normal road tar.
Driver attitude I notice in the tunnel
1. Seem like me and the VIOS follow at my back are the only 2 vehicles travel at 60KM/H in the tunnel. Every cars overtake us easily.
2. There is a Perdana make a last minute swing at the SMART tunnel entrance and it even hit the plastic pole. What he has in his mind?
3. Some cars didn't turn on the main beam.
Thing to improve for SMART tunnel,
1. Overhead signboard (exist name) place after the junction. WTF is this? and who is the great designer for this? SMART tunnel did put some small standing signboard to indicate the left and right exist (Bukit Bintang and Jln Tun Razak i went today). The permanent overhead signboards shall place it many meters ahead before the junction, this will help
a. Get the driver prepared and stay in the correct lane earlier.
b. No last minute swing at the tunnel, which may prompt for accident.
c. Smoother traffic without all the lane changing.
