I worked on the Kuala Lumper 'SMART' tunnel, now this was originally designed as a flood water relief tunnel so for long periods of time it would stand idle. A contractor bidding the the job suggested using as a traffic tunnel when idle, two decks were incorporated much the same as Seattle's. Signage etc. had to withstand water, escape routes had Submarine type doors to seal them off during flood use. After being used to prevent down town flooding it would take around 14 days to bring it back to traffic use. A road tunnel under the Suez Canal employed a precast road deck system, this was installed as the tunnel face progressed. The TBM back up gantries then ran on the deck. So there was no delay in waiting for concrete gaining the 28 day strength. Sadly epoxy coated rebar hadnet been invented and the tunnel did suffer rusting rebar, that had to be repaired. So much progress has been made in tunnel design, TBM use in variable grounds with EPB machines etc. I'm lucky enough to have witnessed many of these methods since I starting in tunneling back in 1960 and retiring in 2015. It's always great to see another project completed safely. THANKS
I can just see hackers getting into the control systems, that wont be very good. I'm reminded of the Tanker truck fire in the Caldecott tunnel in Calif in the 80s
@@miniena7774 I agree as a Transportation Engineering Student with your statement. People will just have to find a new way around or take the dreaded option called public transit.
@@Dog.soldier1950 Do you have a background in tunnel construction? The number of lanes is driven by the tunneling technology. They could have created 2 double height tunnels but for the stretch of road and no exits, it will be fine. There are experts who master in this sort of work for a living. Norway is constructing a new undersea tunnel - guess how many lanes each way?

So this tunnel is a doubledecker ???? Bottom goes in one direction and the top goes in opposite direction ???
EPIC.
Epic
A year later, How is it ?
do these fans have a backup electrical system when the electricity goes down?

You mean inspections, Like the big dig in Boston ?
The roof caved in after the inspection killing a driver
Can homeless people live in the emergency exits? asking for a friend.
yes

AM/FM override. Cool feature, but virtually useless. I'm sure 4 people will be glad to get the news.
Only two lanes each way? Roads being replaced are three lanes each way.
There's going to be two lanes each way for bicycles....oh and antifa marches!
More lanes doesn’t equate to less traffic...

@@tannerrobinson5110 pls no, so dirty and full of germs!
what a bunch of whiners
Out of date before it opens
How so? please elaborate.
It has only 2 lanes in either direction replacing the AWV with 4

How about.....NO?
It's a rip off tunnel. They use our tax money to built this tunnel and then make us pay to ride through it
The tunnel sucks ! Glad it created some jobs, but made my job more
Hazardous and longer
