BC Highway Construction - Page 89

I'm mildly surprised to see that BC doesn't seem to have any full systems interchanges (4 way all way), not even legacy cloverleafs. Are there any examples I am not aware of?

There are several three way full system interchanges.

The 99 / 17 (SFPR) is perhaps the closest.

The 99 and the 91 in Richmond? But directly to the west the freeway ends.

Is it perhaps related to how many of our highways are shaped by the mountainous terrain and don't always meet on a perpendicular?

That is definitely a big part of it.

Most highways here meat at three way junctions.

I think the 99 / SFPR is the closest we will have to a 4 way free flow junction. Though I think now it is missing one of the eight directions.

You cannot go from Hwy 99 WB to Hwy 17 NB, nor can you go from Hwy 17 SB to Hwy 99 EB.

I wonder what the interchange of TransCanada / Lougheed Highway would be considered. It seems more like a very short concurrency instead and is made all the more complicated by the Mary Hill Bypass.

Strange as WB to NB is usually a simple movement.

It seems that for some reason they don't want Hwy 17 to be used as an alternate to Hwy 91.

It also has 6 out of 8 directions. Definitely a very unique interchange though and a huge improvement over the equally-strange interchange that used to be there.

That movement was going to be added as part of the scraped (thanks NDP!) highway 99 upgrade / bridge project that would have been long completed by now.

Where the hell is the money going. Still 2 after this.

Spent an extended weekend in the lovely city of Victoria and area. Drove north along TCH & BC19. There only seems to be about 14kms required to twin through the Malahat. I got thinking they should transfer the group that just finished the Kicking Horse Canyon Phase 4 in Golden to tackle this stretch. They now have experience building a highway on the side of a mountain.
Also wondering why BC19 doesn’t retain the TCH1 designation north of Nanaimo ?

TCH 1 takes the ferry from Nanaimo to the Mainland and heads east. Incidentally, I think the original numbering (c. 1940) did have BC 1 continue north to Campbell River, while the Mainland section of BC 1 headed east from Vancouver.

Good memory! According to Wikipedia:

Quote:

The Vancouver Island section of Highway 1 was designated in the initial numbering scheme announced by the provincial government in March 1940, along with Highway 1A. It originally connected Victoria to Kelsey Bay, a small coastal community north of Campbell River. The Vancouver Island section was truncated to downtown Nanaimo in 1953, with the section north of Nanaimo being re-numbered to Highway 19. When BC Ferries took over the ferry route between Departure Bay in Nanaimo and Horseshoe Bay in West Vancouver in 1961, Highway 1 was extended to the Departure Bay ferry dock.
