It's for drainage. The one theory I have for why they split the tunnels into two is that federal regulation probably has some rules when it comes to tunnel length and the requirement to build a ventilation system to take out vehicle exhaust. The price tag probably would have risen substantially if they made one long tunnel with those requirements as opposed to two smaller tunnels. On top of that, you probably also would have been required to build emergency exits every-so-often. Again, that's just a theory I have. 4 1 Quote Link to comment Share on other sites More sharing options...

On top of that, you probably also would have been required to build emergency exits every-so-often. Again, that's just a theory I have. I think you are correct on the ventilation aspect. I recall reading about such ventilation requirements regarding the below-grade segments in NHHIP. If a "tunnel" is more than x' feet long mechanical ventilation is required. Found this: NFPA [National Fire Protection Association] 502 does not mandate that mechanical ventilation be provided in tunnels less than 1000 m (3280 ft.) long, but does require an engineering analysis be performed. Historically, for short tunnels, common practice is that they are not mechanically ventilated. However, societal awareness about the serious nature of fires in road tunnels, coupled with the development of NFPA 502, has led to a need to demonstrate quantitatively whether mechanical ventilation is needed. NFPA 502 states that emergency ventilation shall not be required in tunnels less than 3280 feet in length, where it can be shown by an engineering analysis that the level of safety provided by a mechanical ventilation system is equaled or exceeded by enhancing the means of egress or the use of natural ventilation 5 Quote Link to comment Share on other sites More sharing options...
Popular Post hindesky Posted April 5, 2021 Popular Post Share Posted April 5, 2021 Notice the track hoe down in the future water feature that will run under the road between the tunnels. This mound of dirt has to be about 40' high so far. The picnic loop was packed with people with almost all the parking spaces being used. 16 Quote Link to comment Share on other sites More sharing options...
gene Posted April 5, 2021 Share Posted April 5, 2021 Great photos @hindesky and yep i went for an early morning pre easter brunch bike ride and so fun to see all the activity at the park and loop! and heck yes, this tunnel progress is so darn impressive and is looking amazing! cannot wait to see it finished! 3 Quote Link to comment Share on other sites More sharing options...

Popular Post innerloop Posted April 13, 2021 Popular Post Share Posted April 13, 2021 The dirt is getting higher on the north side of the tunnels. And they are installing that black covering on the outside of the concrete. I haven't seen any progress on the end of the tunnel transitions yet. 11 Quote Link to comment Share on other sites More sharing options...
thatguysly Posted April 13, 2021 Share Posted April 13, 2021 Are they building a bridge over the water feature between the tunnels or will it be a culvert system? The rendering make me think culvert but that doesn't seem as hospitable to the ecosystem. 2 Quote Link to comment Share on other sites More sharing options...

Popular Post hindesky Posted May 14, 2021 Popular Post Share Posted May 14, 2021 Rode around parts of the build. Got a chance to talk with a Memorial Conservancy employee that was putting away his drone. He said he flies the drone around to check progress about every other week. He mentioned that they will be closing the old road that went by the baseball fields June 1st, this was the road where I was talking to him on. They are doing this so the can continue the hill on the southward of the tunnels. End of the year they expect to re-open the new Memorial Dr. so they can continue northward with the hills. I asked if there is a way to get to 610 on a bike and he said they built a crushed granite trail for bikers and joggers. It ends up by the railroads and just south of the jogging building. Tellepsen's trailers are there too. Everything should be finished by the end of 2022 and they are on schedule as of now. 16 3 Quote Link to comment Share on other sites More sharing options...

gene Posted June 10, 2021 Share Posted June 10, 2021 that new crushed gravel path for foot and bike traffic that replaces the old picnic lane road is super fun to ride on with it's curves and "in the middle of the woods" feel! It does kinda go a bit out of the way if you are in a hurry to get home like i was the other night haha...but yep it's awesome! 7 Quote Link to comment Share on other sites More sharing options...

X.R. Posted June 14, 2021 Share Posted June 14, 2021 (edited) Went by this weekend, and its crazy to think this is actually happening and how quickly its moving. Like, every other week it seems they are making visible, substantial progress. Are they going to put fences up or something on the sides of the land bridges? You know people are gonna accidentally let go of a dog, or someone is going to kick a ball real hard, or throw a disc too high and its going to go over. I was wondering that once I saw the height of the land bridge. Edited June 14, 2021 by X.R. 7 Quote Link to comment Share on other sites More sharing options...
gene Posted June 14, 2021 Share Posted June 14, 2021 (edited) edit: oh i see what you mean...some kind of fence at the edge of the bridge where it ends over the road/tunnel entrance...heck yeah, they better! I can just see exactly what you are saying happening! From what i knew the land bridges are open to everyone to cross and even have picnics on as i remember somewhere they spoke about how from the top of the land bridge you would be able to have great views of both downtown and uptown...

Popular Post Naviguessor Posted June 15, 2021 Popular Post Share Posted June 15, 2021 (edited) I've decided to believe that this is being designed by professionals who know what they are doing, know how to spot risks and know how to mitigate them. It's the same people who decided not to populate the Eastern Glades lake with Crocodiles and chose crushed granite rather than crushed glass for the running trails.

wilcal Posted June 15, 2021 Share Posted June 15, 2021 The land bridge I saw, I believe in Alberta, which is used exclusively by animals still had a fence on it I believe. Basically, I would count on a fence. Quote Link to comment Share on other sites More sharing options...

Good to know. 🙄 https://www.canadiangeographic.ca/article/banffs-famed-wildlife-overpasses-turn-20-world-looks-canada-conservation-inspiration The fencing (on both the bridges and the entire roadway) in Alberta, is there to eliminate deadly collisions between vehicles and wildlife (deadly for wildlife as well as humans). Pretty different situation from the bridges being built in Memorial Park My best guess is: No fencing. I don't recall this video being posted here.

Hey, you found the exact bridge I remembered and it was exactly the way I thought it was. Nice work! Memorial Park has mentioned that the land bridge is designed to be used by animals to avoid having to cross Memorial Drive. I'll argue that I'm guessing a certain % of Memorial Park users are dumber than the average wildlife. That video shows it with a raised concrete edge at some points and a flush edge at others.

Luminare Posted June 16, 2021 Share Posted June 16, 2021 Y'all get into some strange specifics sometimes. Wow look at that crazy land bridge.....wait where is the railing, oh you know someone is going to muck that up! There will more than likely be a railing. Obvious can't confirm as I'm not on this project, but my professional opinion would say, yes indeed due to code reasons on multiple fronts, its also above a busy rode you will see a railing, and given what I've seen the design packets floating around they will probably make it flow seamlessly with the design. Only thing I don't know is if one would be able to walk up to it. I imagine the edges around and up to the pinnacle of the bridge will be extensively landscaped. 2 1 Quote Link to comment Share on other sites More sharing options...
