This is what happens when you cut corners and go after "value engineering".

Huitt-Zollars, the supervising engineering firm, told the city in a letter dated May 25 that there are two possible fixes — or "cable system retrofit alternatives," according to Broadnax — that might resolve the vibration issues. One, the firm said, involves replacing rods and sockets connecting the arches to the bridge.

The other involves replacing the entire cable assembly — and, essentially, starting over.


I didn't really pay much attention to this issue at first, but, now that I've read the article, this is worse than I thought...

It is worse than most people thought and it deserves much more attention, a little embarrassing news coverage can do wonders for fixing problems.

I swear the City of Dallas is so incompetent at times. Who skips a cable stress test to save money? I really can’t understand the thought process behind that. Now, the City has to pay millions just to fix an issue that could have been done right the first time.

Even if they would not stick in a courtroom, I'd like to see charges brought against the people or person making the decisions that lead to a worthless bridge.

Probably the same people who made budgetary savings on the Water Rapids down in the Trinity. Supposedly that was a city staff design change as well. The original design drawn up for the water rapids was much prettier and safer in design but arguments between the engineering firm and the city on cost turned it into the boondoggle they are having to tear out now. Cost savings measures were implemented severely.

I get the feeling though its not the staff member who is making the decision its someone else higher up who keeps pressuring to save money to the extreme no matter what the product result is. City staff members operate based on political direction from higher-ups dealing with council members, community leaders, and money talks groups outside the official channels. It seems like someone higher up is so worried about cost overruns they may be forcing changes that are costing the city tons of stress and more money.

McDermott Bridge May Have to Be Demolished Like Fake Kayak Rapids
http://www.dallasobserver.com/news/some ... d-10880572

Here's another article on the subject (I haven't had a chance to read this one just yet). I really wonder how all of this will play out, because this is quite a disaster at the moment.

Personally, I only care about the hike/bike trail. Creating a loop in the Trinity River area might be a popular draw for runners/bikers, so that is my number one priority. I hope that all potential outcomes would involve, at the very least, keeping the pedestrian walkway.

Dallas cheaped out and now has to spend millions more repairing Calatrava's second bridge
Huitt-Zollars' vice president Charles Quade told the city that depending on the fix, repairs should take between eight and 15 months. And it could cost — again, an estimate here, because the contractor hasn't been consulted — between $2 million and $6 million.

"We must keep in mind that doing nothing is always an option," Lee Kleinman, chair of the council's Mobility Solutions, Infrastructure & Sustainability Committee, told me Thursday. He wants city staff to come to his committee next month and explain what the hell's going on.

"Why spend any more money on it," Kleinman said, "when there are so many more needs in the city?"

I hate that 'leave it as is' is an option here, I really hope they are not seriously considering this. I get there are so many more needs in the city, but, if that's the case, why build the bridge in the first place? Frustrating.

The incredible part of it all is that WE allow it to continue. WE meaning you reading this. Time to put a stop to it. Dallas can't afford more of this.

What are the avenues to put a stop to this? What is your suggested outcome?

Those responsible for prior mistakes can never be allowed to work on future projects. The same handful of people are at the root cause of every blunder involving bridges, whitewater features, tree cutting, borrow pit excavation and desecration of cemeteries. The same people. It is too expensive for the taxpayer to allow them to continue.

When NBC 5 last reported on problems with the Hike and Bike bridge in January 2018, city officials hoped the problems could be solved within months.

A year later, an email from the City of Dallas Wednesday said the city is still waiting for information from the State of Texas about the cost of necessary work on the cables. The email said the cost could be as high as $10 million and up to 36 months of work could be required.

I've basically written off this project and just assume that it will never open. I guess with my expectations set so low, there's no way I can be disappointed.

What a cluster this has been though, it's a damn shame.

This is pretty insane. So we essentially just paid for what is now a giant sculpture at a cost for something that is designed to structural characteristics.

I never thought it would get built in the first place my guess is that with State involved will delay but it will get done eventually. Visually it certainly is better than nothing at least while we wait for a fix.

I still don't get why it can't be opened. Under what case study is a few walkers or joggers going to be in more danger than the tons of cars already passing by?

Well for a couple reasons..

1) The Highway isn't supported by the cables. Only the pedestrian portion.

2) the cables have failed stress testing; therefore they are deemed unsafe for use.

3) The Engineers won't clear it because if it does go to hell they'll be in so much legal trouble. They'll probably lose their licenses and jobs!

I get that, but the cables are huge and they are adjacent to the roadway (I don't drive that bridge often) but I'm pretty sure if one of those cables fell or broke loose and swung it would hit the road and cars.

Totally... The bridges structural integrity is what it is, regardless of the presence of some people walking on it or not. If it's truly at risk of failing, the risk is to much more than just those few potential people walking on it. In fact, just due to the traffic volume of this bridge, the threat is much greater to the vehicles than it is to the walkers.

Except that cars are much more protected from flying cables than pedestrians and bike riders.

I keep waiting for them to decide that the flying cables issue is enough of an issue to go ahead and close the frontage roads too. Honestly, why can't they fix this?

More protected, sure, but not impervious. I would think that if the cars were at risk at all (even if only a little bit), then that portion would have been shut down as well, no?

They should have never built these arches in the first place. They look awkward and out of place. They perfectly epitomize vanity and waste. Now, if the freeway bridge had been built as one structure supported by said arches, then the arches would be fine.

So, Dallas paid roughly $51,111 per linear foot of paved bike path, which is currently non-functional. Wow. Calculations based on the $115M cost of the arches divided by roughly 2250 feet of the path (1125 each direction).

Dallas must own the dubious record for most expensive bike path ever built. Good job!
