![]() The design also means it can only be used with 12” or flatter radius fretboards, so it won’t work on 7.25” or 9.5” radius guitar necks. You can only adjust the action via the two bridge posts, which means you have to make sweeping changes rather than being able to individually adjust the height of each string. Whilst it’s a big improvement over the wraparound, there are still some similar limitations with this type of bridge. Due to this design, you also get more play in adjusting the intonation on the bridge saddles, particularly with the Nashville-style tune-o-matic bridges. The break angle of the strings over the bridge, as they move toward the stop bar, allows for much-improved sustain over the wraparound. Transcript provided by NPR, Copyright NPR.- Can’t be used with round-radius fretboardsįirst used on the 1952 Les Paul Custom, the tune-o-matic was the natural evolution of the wraparound, keeping the initial bridge design whilst adding a stop bar to increase the length of the string and add a break angle. ![]() GONYEA: That's WHYY's reporter Tom MacDonald. And people still can't get into the area right around where the collapse happened. There was no reason to be open because nobody was there. One person I talked to earlier this week said they closed three hours early because there was no use staying open. They are saying that they don't have any customers. What are small businesses who are on or along those side streets doing? And they got to be losing customers. GONYEA: And there are a lot of side streets that are just blocked off because of this. But I guarantee you, before this is over, somebody is going to come up with a number on it. So they're not putting a number on it yet. And that's got a lot of people saying that this could lead to food price increases and people who want to take travel. Eight percent of the national economy allegedly moves up and down this corridor in the Northeast. But how much pain is that little gap causing the local and national economy right now? But I mean, I'm thinking of those "Fast And Furious" movies, right? And a good stunt driver could probably clear this gap. GONYEA: From the aerial pictures that you see, this gap in I-95 doesn't look all that wide. Now, there are other detours, and no two are the same. ![]() It all depends on the time of day, depending on travel, depending on how many people take the main detour. It's the northbound direction that's a longer trip. MACDONALD: Well, the trip in the southbound direction can be done relatively quickly. GONYEA: And what are motorists doing in the meantime? I mean, obviously they're taking detours, but is there some sense of how much time is added on to the average trip? MACDONALD: Well, that is the very important question everybody wants to know and nobody's telling us. GONYEA: And any idea how long it's going to take? If you think about frosting a cake, they've got a conveyor belt taking this stuff up and building it up layer by layer, and then they're going to top it off with some asphalt. And it's taken down into small chunks, I'd say about the size of a stick of gum and about three-, four-inches wide. It's something that resembles a plastic Styrofoam cooler that you would use for a day. The interesting part about this is the material. So they have now taken off the steel from the top of the bridge and the concrete, and they are just going to fill the void up and put in six lanes of asphalt over top of that new fill. ![]() MACDONALD: They're going to take the chunks and fill in the highway. A couple of days ago, Pennsylvania Governor Josh Shapiro announced a reconstruction plan involving 2,000 tons of recycled glass pieces, I guess, is the word. Literally, the steel girders underneath the bridge were twisted like a pretzel. The truck exploded, and it melted the bridge. He was driving a truck filled with 8,500 gallons of gasoline. But at this exit, there's a curve underneath the highway. MACDONALD: We have a video that was taken on social media that they think is accurate. GONYEA: First, what do they know so far about why the tanker truck turned over and the overpass collapsed? TOM MACDONALD, BYLINE: Thank you for having me. WHYY's Tom MacDonald joins us now to bring us the latest. It's also shut down traffic in both directions on the indispensable East Coast highway and forced vehicles to take detours along slower roads. The incident killed the truck's driver, but no one else was harmed. It's been nearly a week since an Interstate 95 overpass outside of Philadelphia essentially melted when a tanker truck burst into flames underneath it. ![]()
