Metro Vancouver Road Infrastructure Discussion

Sections of highway are probably a lot quicker to rip up and repave versus doing the same thing with concrete.

An article about the I-5 Revive project:

Giant metal "blade" that drops onto the old concrete panels to crack them so they can asphalt over it. The second paragraph talks about how the metal dowels that aberdeen was talking about.

Several relatively new techniques make it possible for concrete contractors to rehabilitate and resurface highways efficiently with minimum traffic interruption. Among these is fast-track concrete pavement technology, in which high-early-strength concrete is used to allow reconstructed roads to open more quickly. While conventional concrete mixes might require a curing time from five to 14 days, fast-track concrete can meet roadway opening strengths in 12 hours or less. Although combinations of ingredients vary, high-early-strength concrete commonly includes a higher proportion of the standard Type I cement to water or contains high-early-strength cement, known as Type III cement. Type III cement is virtually identical to Type I, except that Type III cement particles are ground much smaller. The smaller cement particles increase the surface area, allowing more cement contact with the water in the concrete mix, meaning faster hydration is achieved. Generally, fast-track concrete provides good durability because most of these concretes are air entrained and have a relatively low water content—factors that improve strength and decrease the chloride or salt permeability that damages steel reinforcement and contributes to deterioration.

Another relatively new technique that promises to improve highway smoothness and longevity is dowel retrofitting of existing concrete pavement that has undowelled slab joints. Since 1980, the slab joints of most new concrete highway pavements in areas where heavy loading is anticipated have been dowelled with 18-inch long smooth steel bars. The dowels bridge the joint sawed between the pavement slabs and help transfer traffic loads from one concrete slab to the next. The retrofitting technique involves cutting slots across the pavement joints, inserting the bars, patching the slots with fast-track concrete mixes, and then diamond-grinding the road to obtain a smooth surface. Department of Transportation officials in Washington—the first state to undertake dowel retrofitting on a large scale—expect to extend the life of some of the state's 30-year-old concrete highways by 10 to 15 years using the new technique.

I wonder if asphalt provides better control for preventing water from pooling versus having to grind the concrete down or installing grooves in a concrete road surface.

What are your thoughts on concrete streets though? Especially brand new ones. Seattle new waterfront boulevard is all concrete. It looks and drives fantastic.

I haven't been down there. I remember driving up to SFU, they had concrete on the Gaglardi side in the 90s. It was fine but below average.

Nothing beats new asphalt.

Sure dream on.

Building a new North Shore bridge a 'huge priority' for BC Liberal leader

Issues plaguing North and West Vancouver are caused by an NDP government that’s too slow to act, says B.C.’s leader of the opposition.

Kevin Falcon, Vancouver-Quilchena MLA and head of the BC Liberal Party, took questions from reporters on Wednesday at a roundtable discussion hosted by Kirk LaPointe, columnist and vice-president of editorial at Glacier Media.

Answers provided by Falcon, who lives in North Van and previously worked for developer Anthem Properties, were often characterized by criticism of Premier David Eby and the BC NDP for its inability to push projects ahead, and the need to remove excessive red tape from the private sector.

When asked how to solve congestion related to the Ironworkers Memorial Second Narrows Crossing, Falcon said the issue is going to required a new bridge, “no question about it.”

“That crossing is now over 60 years old – it literally is starting to fall apart,” he said. “I was just going over about a week ago, when a chunk of the bridge literally fell through and created a hole.”

“What the current government is doing is time wasting: They do studies and then they’ll do more studies and study the studies,” Falcon continued.

As minister of transportation from 2004-2009, Falcon said he prioritized urgent issues like the Sea to Sky highway upgrade and the Canada Line.

“We’ve gotten those things done. The Evergreen Line got done, and now they’re starting to do the corridor through Vancouver. That’s great, but we now have to look at the North Shore. It’s a huge priority for me,” he said.

"Spend X billion to replace capacity that's already there" doesn't seem like a very effective way to flip the North Shore blue.

I wonder if they plan on a totally new bridge or just a redecking for the Second Narrows when it reaches it's end of life in 35-45 years.

When they announced the current renovation work on the structural elements of the bridge in 2021, the statement was that with proper maintenance the bridge wouldn't need replacing for up to 45 years. So that suggests that when it reaches that point it's a total replacement, not just a new deck.

Remember that the City of Vancouver has a policy of no new (additional) lanes into the City.

true, though the province can ignore that if they want to.

Delta wants a new bridge out of Delta and New West didn't want a new bridge into New West, but neither is getting what they wanted either. If the province decides that an infrastructure project is going to get done, it's going to get done.

Traffic lanes out of the city, sure - but absolutely no new lanes INTO the city!

That's not true, New West got exactly what they wanted.

[officedweller]

I would say Oak St. Bridge should be high priority for 2 more lanes, but even the Liberals did not have it in their Hwy 99 plans.

Not exactly, New West didn't want 6 lanes but the bridge is designed and built for 6 lanes with only 4 used for vehicles but nothing stopping that changing in the future. Only takes one BC Liberal (BC United...) car enthusiast government to make that happen.

i disagree with this statement. you make it sound like its just a matter of repainting lines and moving barriers (what was done with the Alex Fraser Bridge). it was not built for 6 lanes at this time.

but that's misleading, it'll take a fairly major construction project to cantilever the bridge, and this will probably have 9 figures of money attached to it.

New West wanted to remove Royal, East 8th Ave, and portions of East Columbia & Ewen Ave from official truck routes and was denied, the city did not get exactly what we wanted, still have heavy trucks polluting residential streets all day long.

The bridge is only 4 lanes because the province has never approached the city about a better solution to traffic management with the increased traffic volume, even though it's well within the city's traffic management plan to have a tunnel under 3rd avenue to deal with that, it would just require some funding to the tune of billions from the province (this is also mentioned as one of only two new road links in Translink's Transport 2050 plan, so here's hoping it eventually happens).

The borders they have for the Seymour Creek 2 IR for instance are seemingly just completely made up.



The actual surveying can be found on the Government of Canada survey site here.



It makes fantasy transit planning difficult.

Except for maybe the roads intersecting the reserve the Google Maps version seems like it's identical to the survey map you posted.

The borders are a complete mess so I wouldn't blame Google Maps for that.

I would encourage you to look closer. It's pretty evident that the borders are completely off pretty much everywhere.

I'll reiterate, this used to be correct on Google Maps but at some point they updated and messed up their information, so I think it's completely fair to blame Google Maps for that.

I assume there's some problems with potholes or something?
