Clem 7 Tunnel

Who has had a drive in it?

Saw the news and looks interesting. Lowest point is 60m under ground.

It's free to travel and use it for another 10 days or something.

I'm gonna drive it this coming Saturday morning.

It will be really interesting tomorrow, during the commute

Most interesting entrance is from shafston avenue, i can see a few bingles round that loop

BE WARNED, there are speed cameras all over the place

There are four speed cameras in each direction. Don't bother looking for them, they look like everything other black box on the ceiling. They can move around within the tunnel and there is no signage as to their exact location - only signage is at each of the portal/ramp entrances.

have a look here
there is also the Channel Tunnel which is 50kms long and runs from britan to france which was opened in the 90s
this isnt the 1st nor the longest tunnel that runs under any body of water
wiki article

that being said i will go for a free drive thru this one as soon as i get some free time, im so damn swamped at uni atm

on the upside there was heaps less traffic everywhere else! behind a very loud commodore and skyline... sounded pretty sweet when they both redlined in the tunnel! (there was nothing else interesting to do haha!)

regarding speed cameras... hopefully they are set to 85ish, because if they are really strict will make more than the tolls!

Just so everyone knows:

I have worked on the Clem7 for the last 5 years as a traffic engineer. I am happy for any questions about the tunnel to be posted here.

I will NOT answer any questions related to traffic volumes, however, I can provide some clarity on the general arrangement and operation of the tunnel.

Cheers

Is the general speed limit going to be set at 80km as a maximum?

Do they vary that speed depending on traffic conditions/accidents?

Is there anywhere we can read up on the radio broadcast system they use?

haha love it how you just launch the car at 1min 6secs, looked like the car was going to take off!

I did the voyage down tonight, and can see that it will make a hell of a difference within the city, but not viable for me...

I couldnt get anywhere near 70ks tonight @ 9pm, but shifting back to 2nd and letting the car catch up was awesome to the ear!

Theres actually 8, 4 in each direction

Probably the only place you could go for a 100km in an 80 zone and lose your license in less than 3 minutes

Funny enough I never exceeded the 80 limit anywhere in the tunnel.
It is a nice drive, and it would be very easy to exceed the speed limit, but i found I was driving at about 50-70 most the way thru it.
I did get to 80 at one stage.
But that felt like it was speeding for some reason.

ditto, must be due to the confined space of the tunnel I would think?

Question for Darryl, is it actually two tunnels or one big bugger?

There are 2 tunnels, one going each way, and there was a separate boring machine for each tunnel.

General speed limit will be 80 km/h.

The level of traffic in the tunnel will govern the speed - heavy traffic leads to lower speeds etc. If there is an incident in the tunnel the variable speed signs will gradually slow traffic down as you approach the incident to allow safer braking.

I don't know much about the radio broadcast system, but I did read somewhere that the major radio stations have a cut-in frequency that override the main signal with a short-range transmission.

Things I do:
- Strategic traffic modelling (across Brisbane City as a scale reference)
- Micro-simulation traffic modelling (for intersections, road corridors, public transport etc)
- Major road upgrades (highways, tunnels, urban upgrades)
- Road/traffic impact assessments for development applications (mines, office blocks, industrial, residential, wind farms, pretty much anything else) I even assess other firms development applications on behalf of councils sometimes too
- Parking studies which might be for a single parking area or across a city
- Pedestrian / cyclist planning
- Public transport planning

Oh, and on the side I dabble in geospatial mapping.

Interesting. Never really realised there was so much to do with traffic, i understood that thered be flow studies and things like that. But didnt realise planning went down to that level.
