https://en.wikipedia.org/wiki/Directional_boring
Quote:Directional boring, commonly called horizontal directional drilling or HDD, is a steerable trenchless method of installing underground pipe, conduit, or cable in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical. It is suitable for a variety of soil conditions and jobs including road, landscape and river crossings.

The tunnel to the Toronto Island airport was dug using a small TBM to bore 1.8m tunnels that served as a roof structure, and then they excavated below to create the full tunnel.

Oh, I know that horizontal drilling is a thing, but I imagine that the diameter of the bore would be larger than you would typically see drilled. That's why I was wondering about reaming. I know that they use the technique for placing vertical shafts in mines, but I had never heard of it being used in horizontal drilling. Now that I'm home, cursory searches seem to suggest that reaming a horizontal hole in soil is possible.

Maybe I'll trundle over there in the next few days and see if I can take some photos and figure out what's going on.

Probably infrastructure. from the plans it looks like the traffic tunnel is going to be on the east side of 85.
To the other point, yes it was 100 and went to 90 at least 20 years ago? That's back when it was an 'expressway' without the volume/bottlenecks nowadays.
Yes, it was 100. Went down sometime in the mid 90's, due to too many accidents.
RE: Highway 7 - Kitchener to Guelph - Canard - 01-26-2017
The West portion has them but the North part doesn't.
RE: Highway 7 - Kitchener to Guelph - p2ee - 01-27-2017
Yup, only the portion in Waterloo doesn't. But the limit should be 100 throughout all the other portions.

There'd need to be some serious straightening on the curves from Wellington to Bridgeport to make it safer for 100km'hr travel. Currently it's barely safe at 90.

There is only a grass median west of Ira Needles. The Expressway continues another dozen KMs or so out to New Hamburg.

Additionally west of Fischer Hallman the median has a much wider cross section than the urban sections.

There is no plan for Highway 85 to get concrete barriers. At last check, the MTO is in wait-and-see mode.

Just found this site: https://www.ontario.ca/locations/building-ontario/
They have the new highway 7 as: "Estimated completion: 2020-21". I think that's roughly what people were expecting*, but not sure if I'd seen anything definitive before other than beyond 2020.
* I think most of us thought a bit later like 2022, but if they estimate completion as 2020-2021, that probably means 2022 is likely.
RE: Highway 7 - Kitchener to Guelph - rangersfan - 03-10-2017
This has likely been discussed but when looking at the diagrams on the website below it looks like there won't be northbound access to the 85 off of Bruce St where it is today but instead through the Bruce St extension.
If you are in the Bruce St area and wanted to head towards Guelph what is the nearest access to highway 7?

RE: Highway 7 - Kitchener to Guelph - KevinL - 03-11-2017
You're correct, it's by way of the Bruce extension and the Wellington extension - looks like four traffic lights, including both a right turn, and a left.
