Dreamers or not, we wouldn't have gone to the moon if it wasn't for the Cold War. The main reason we went to the moon is because the U.S.S.R. sent a satellite into orbit.

Is it bad to have a 4 lane highway have a wide median and then when it becomes 6 they use the median to fill in those lanes?

It depends.

If that 4 lane highway is through farmland/prairie and will likely need 6 lanes in the future, sure.

If it's a 4 lane highway blasted through a mountain of rock, you need to blast that big median too. If there's no foreseeable need for 6 lanes eventually, why bother? Sure, you have to account for fill in other areas of the project, but still.

That's what I used to think too, until someone who works in road building (not sonysnob aka AsphaltPlanet this time lol) told me that rock blasting is actually a matter of economy of scale. Let me find that quote.
Granted, it's a bit technical and even I have a hard time following. These are replies to my post too.

So it's just a question of width of your cut. Which is less of a factor than the question of whether you need to do it in the first place

Yes once you've got the crews deployed it's an economy of scale.

I looked that up a few days later just to verify, and the stuff that I read actually backed up what he said.

Now, I need sonysnob to take over the mic.

Actually, sometimes they don't. The 400 north of Barrie where it is 4 lanes proves that. They blast each of the 2 lane ROW separate. Mind you, they have sort of been changing that for the 4 laning of highway 69.

I've always been wondering. What's the geology like between Crown Hills and Waubaushene? I see hills but I don't know if it's granite or earth underneath those (especially that 2% slope at Exit 147 - Highway 12 West).

But yes beyond Exit 149 you start seeing granites.

It is much like south of Barrie till you cross the Trent Severn Waterway.

It's not a bad idea because it won't be fun when people hit those median rock cuts at 120 kph.

When rebuilding today, every attempt to bring it to standard should be made, and if not there has to be some significant external factors demanding why it wasn't. New build on a brand new right-of-way, there's almost no reason to not build to standard. In either case though, there's a lot of legal and professional liability involved in not building it properly. So again, any reason for not building to standard has to be very significant.

The above quote is from the Ontario Road Group on Facebook.

Okay that makes sense.

Just get Danny boy to make your rock cuts. Problem solved.

It's not that memes aren't popular it's just that they're mostly lazy for a discussion forum and most of our members are too old to get them.

Well said. I find them about as funny as most Tik Tok videos.

^Impressive!
Had no idea this was happening.

Dengler Avenue · #**8735** Posted **Jan 15, 2021, 11:34 AM**

Roundabouts at every single interchange in a rocky area too

Then again, once rock blasting needs to happen, one may as well go big.

Nova Scotia loves their roundabouts.

My apologies if this has already been discussed, but does anyone know why Hwy 107 didn't simply tie into the Bedford Bypass and the 101/102 interchange? It seems it would have better integrated into the existing highways.

Dengler Avenue · #**8738** Posted **Jan 17, 2021, 11:12 PM**

I honestly think that 101/102 mess needs a complete remake one of these days...

ssiguy · #**8739** Posted **Jan 18, 2021, 5:22 AM**

Must be nice. Last time BC built a freeway was the 1990s.

Like Dengler Avenue said the 101/102 interchange is a mess and heavily congested in traffic (pre pandemic).

The Bedford Bypass regularly backs up 5 km or more in the morning (pre pandemic) from Akerley Blvd (stop lights) in Burnside.

I think they wanted to avoid the bypass traffic interfering with the flow of the new expressway, as well as leave the 101/102 interchange available for a long overdue overhaul. A flyover interchange on the Bedford bypass (near Highway 2) may have been difficult to construct due to extremely close residential neighborhoods and/or DND's Magazine hill (East coast Navy munitions storage).
