People around the area have reported hearing today's explosion from considerable distances from the bridge. Did you? Let us know where you were if so, and we'll map the responses to see how far the sound traveled.

How far could the blast be heard?

Two hundred fifty-one feet down, another 251 feet to go.

Today’s successful dropping of a 250-ton section of original Kansas River bridge along the Kansas Turnpike now has officials turning their attention to 10 a.m. Thursday, the anticipated time for detonating another 6 pounds of explosives to cut through the rusted steel structure.

“This went great,” said Rex Fleming, the turnpike’s project engineer, at the blast site Sunday afternoon. “We’re ready to do it again.”

More than 150 onlookers crowded into parking lots, under shelters and up against trees Sunday in Burcham Park to observe the first bridge blast. It’s all part of an ongoing $130 million project for the Kansas Turnpike Authority, which is replacing its 55-year-old river bridges, overhauling two Lawrence interchanges and making other upgrades through the end of 2011.

Jeremiah Seibel, 11, watched the blast with his mom, dad and 4-year-old brother. He said the explosion didn’t differ all that much from the firecrackers he’d seen obliterate plastic cups.

“It’s just bigger,” he said. “I just knew it’d be awesome.”

Officials moved up today's scheduled blast time in anticipation of a break in the rainy weather arriving in the Lawrence area about noon. The first drops of rain started dotting Lawrence pavement about 7:30 a.m. today, and a few hours later were soaking the entire town — including the 250 tons of steel set to be dropped by detonation. The decision came just before 11 a.m., as officials observed a break in Emporia. The new 12:15 p.m. time was set at 11:50 a.m.

Officials had been expecting rain all along. The only question was how much rain would come, and whether a break would arrive.

The turnpike’s lanes needed to be dry enough to keep pavement safe for traffic to slow down during “rolling roadblocks” led by the Kansas Highway Patrol on either side of Lawrence as blast time approached.

The explosion left no debris on the new Turnpike bridge. Turnpike traffic was stopped in both directions for the explosion. Soon after, traffic resumed.

    Is the loud commercial that hijacks your computer necessary?

  2. chargdup (anonymous) says…

    Horrendous. I wanted to watch this, but the ads and the music made me leave.

    I have AdBlock :)

    Really. Screw that. Didn't know you could feel a shutter. I thought they covered windows. Are LJW writers illiterate?

  5. Hop2It (anonymous) says…

    And channel 6 is showing.....a replay of KU game.

  6. chic (anonymous) says…

    So, will there be video at least?

    If so, when/where?

  7. Starlight (anonymous) says…

    I hope. The live video was unwatchable.

  8. RoeDapple (anonymous) says…

    Felt and heard it in Lecompton

    I want to watch the unwatchable video! (At least we heard the explosion live.)

    LJ-World is horrible at providing video/audio when it is pertinent. Hell, they can't even embed Google Maps when discussing a location/area. So much potential, so little effort.

  13. Hop2It (anonymous) says…

    So...who watches a replay of KU game the day after? Are there that many Nebraska fans in town?

  14. vinividivici (anonymous) says…

    I could watch the live video just fine. And the audio was low quality, but not THAT bad.

  15. Bladerunner (anonymous) says…

    Very anticlimactic. I am sooooo very glad I didn't go there to watch it in person. And I second Militants wise words.

    Stupid commenters once again complaining that the world isn't perfect to their specifications.

    I went and saw it. It was LOUD!

  17. KSManimal (anonymous) says…

    Good show, but the reporter needs a physics lesson.

    The crowd didn't "hear the blast, then see the bridge drop". They "saw the bridge drop, then heard the blast".

    Good one, KSManimal.

    ROFL, I love how there is a Google Map, although not that useful in this particular article. It's a start!

  22. pace (anonymous) says…

    the ad must be destroyed

  23. bearded_gnome (anonymous) says…

    was actually observed at 1213hrs, north lawrence standard time.
    sounded pretty cool.

    now, can we apply the same forces to: th drunk/drug shelter downtown?

    yeah, why didn't both sections go at once?

    Multi, love the potroast image, you got that right! just do it, get 'er done, no glitz, no glory...

    personally, I wonder why they don't take the downed section, cut it up, and sell suveniers. plus, they could've sold seating at the blast site!

    like fireworks blowing up in a cup, only bigger! that kid's got a future.
