MMan Posted September 28, 2014 Share Posted September 28, 2014 Construction on a new 800 meter long underpass on the Superhighway at Tepbunya junction is to start Wednesday. I have no idea where Tepbunya junction is. Anyone? Link to comment Share on other sites More sharing options...

bluweyze Posted September 28, 2014 Share Posted September 28, 2014 It's on the main superhighway near Teppanya Hospital i.e. near the Tesco Lotus and the road connecting to Meechok Plaza Link to comment Share on other sites More sharing options...

WinnieTheKhwai Posted September 28, 2014 Share Posted September 28, 2014 (edited) Why an underpass instead of a bridge? Because, this. Going under looks a lot nicer. Although apparently some people can't wait turn Chiang Mai into Bangkok ASAP.. Edited September 28, 2014 by WinnieTheKhwai 2 Link to comment Share on other sites More sharing options...

pgrahmm Posted September 28, 2014 Share Posted September 28, 2014 It amazes me drainage wise how in heavy rains these things never flood in spite of the fact they're 30-40 feet below street level......not sure how they do it..... They flood in Calif....you'd think it would be the opposite..... Link to comment Share on other sites More sharing options...
LivinginKata Posted September 28, 2014 Share Posted September 28, 2014 Why an underpass instead of a bridge? Exactly - ask the commuters of Phuket about the 2 underpasses under contruction on the main artery of central Phuket. One underpass is near completion after almost 2 years of traffic jams, and they just started the second underpass just up the road at the next main junction = many years of traffic jams. Overpasses would have been much quicker and cheaper - go figure. Link to comment Share on other sites More sharing options...

Agree about Phuket its farcical..But here in C/M theres a majority of underpasses and they do look so much better..look at this..you'd have no idea that theres 4/6 lanes highway passing in front and below you...much, much nicer than that joke they're building on your island LIK..

WinnieTheKhwai Posted September 28, 2014 Share Posted September 28, 2014 (edited) So to keep the superhighway looking beautiful. Makes sense. Indeed. Compare that with the old ways, with the ugly overpasses on Aom Muang Rd, which by the way took forever to build, too, and disrupted traffic. Especially the Nong Hoy one. And they are also noisier because traffic noise is elevated higher. They're nasty things, and happy that people in Chiang Mai make the extra effort.

I know the point you're making, but Chiang Mai is not the same place you and I knew just 5 years ago. It is an urban sprawl of noise and traffic. Building an underpass instead of a bridge is not going to change that. I was looking at pictures of Huay Kaew road in 2008 just a few weeks ago. I remember my friend, who lived up by canal road in 2008, complaining that the lights were on red for 2 minutes at a time with no traffic going through. It was a fairly quiet road. All that's gone, its already Bangkok. Link to comment Share on other sites More sharing options...
jobin Posted September 28, 2014 Share Posted September 28, 2014 Hey, naboo. I feel your sorrow for things past, like peace and quiet, horse drawn wagons, petrol at US$0.25 per gallon, bread with substance and every town with 3 breweries. It's all gone. The dodo bird is gone too, never to return. I am trying to learn to love the shi**y, ubiquitous, brown and dirty sparrow. Link to comment Share on other sites More sharing options...

jonwilly Posted September 30, 2014 Share Posted September 30, 2014 I have two friends who are highly qualified Civil Engineers (British Terminology) and City Planner (In US Speak). Both have said in the past that Roundabouts are the Proven way to go. Far cheaper then digging the roads up and inso lining some folks pockets. Many will remember the 'Oblong aBouts' when the Chang Puak road crossed the superhighway massive about a kilo long but they certainly kept the traffic flowing. john 2 Link to comment Share on other sites More sharing options...
jobin Posted September 30, 2014 Share Posted September 30, 2014 Can't see how 'round a bouts' could accommodate car speeds of 80 km/hr or more in one direction and 35 km in the perpendicular direction. . I never saw such a thing in USA Interstate hiway. Never been to UK but i suspect everyone there travels at 20 km/hr so those things work OK. The pony carts are a tad slower.

kaptainrob Posted September 30, 2014 Share Posted September 30, 2014 Large multi-laned UK-style roundabouts work very well and some road engineers in Aus/NZ have followed the UK example with great success. UnfortunatelyThai drivers need ~20 years of training to acquire roundabout driving skills so underpasses are far better in the short term. 1 Link to comment Share on other sites More sharing options...

I've taken a few at 80kph(50mph) but then in the UK we have cars that are designed to go around corners. 2 Link to comment Share on other sites More sharing options...

Roundabouts keep traffic flowing. Just needs a little education. Drove up through Mae Rim at the weekend. Underpass construction has begun at outer ring road. Guess what, traffic kept moving. They can always put traffic lights at roundabouts for peak periods. Short cycle, 20 - 30 secs red, keep the traffic moving. Unfortunately, most road design here copies the dinosaurs on the wrong side of the Atlantic..... Link to comment Share on other sites More sharing options...

A thing I've always wondered about is if a combination might work: have the fast traffic underpass in the super highway direction, but an extended area on top that's big enough to accommodate a roundabout for the Chotana traffic and traffic turning left or right. 1 Link to comment Share on other sites More sharing options...

That is a good solution. Many intersections in CM could accommodate additional lanes for a r-a-b or U-turn but are concreted over at kerb height.

jonwilly Posted September 30, 2014 Share Posted September 30, 2014 Gents my comments on Roundabouts are what I have been taught by the Engineer who was Project Engineer for Bangkok's overhead Railway and the City Planner who was Project Engineer on the King Khalid airport in Saudi. Both are retired, live in CM, highly experienced Engineers and both have said separately that Roundabouts are the Proven way to go. Anyone who has lived in Thailand for some years knows that Government contracts are the Thai way to go. john The Project Engineer has final say on Engineering matters and signs the Paperwork required by the Insurance company.
