NORTH LITTLE ROCK, Ark. — Workers are postponing Friday’s planned implosion of the remaining arches of the Broadway Bridge because of lightning in the area.

The Arkansas State Highway and Transportation Department had planned to implode the three remaining arches of the bridge connecting downtown Little Rock and North Little Rock on Friday, but the weather is prompting a postponement until Saturday morning.

Crews are working under a 180-day deadline to demolish the 93-year-old bridge and install a new one. On Tuesday, workers tried to use explosives to take down one arch, but the structure stayed put.

It took about five hours for crews to bring down the arch by attaching a cable to the bridge and pulling it down.
