LITTLE ROCK (November 22, 2016) ~ The floating of the final arch on the broadway bridge that was scheduled for Tuesday morning has been postponed.
According to a press release from the Arkansas State Highway and Transportation Department, the detonation Monday afternoon did not remove enough footing to allow for the arch placement Tuesday.
Information release from AHTD:
In a decision made shortly before 8:00 p.m. this [Monday] evening, Massman Construction Co. notified the Arkansas State Highway and Transportation Department that it has cancelled previously announced plans to float into place the second of two arches that will span the Arkansas River to become the new U.S. Highway 70 (Broadway) Bridge.
Earlier this evening at approximately 4:35 p.m., one of the two remaining footings that supported the steel navigation arch of the old structure was detonated with explosives. A post-blast review of the underwater debris pile revealed that a certain amount of the structure remains intact.
The construction contract calls for the structure to be reduced to elevation 211. The intact remains of the detonated structure are high enough to prevent Massman from sinking staging barges (supporting the new arch) low enough into the river for final placement on concrete piers. Additionally, the remains sit in what will become part of the new, wider navigation channel under the bridge.
Massman is working with the demolition subcontractor to determine the best method to remove the remaining portion of the footing. Although a new date for floating the arch into place has not been determined, it will be sometime after Thanksgiving Day.
LITTLE ROCK (November 21, 2016) ~ Another detonation is scheduled for the Broadway Bridge on Monday at about four in the afternoon.
One of the remaining two footings that supported the steel navigation arch will be the subject of this afternoon’s detonation, according to the Arkansas State Highway and Transportation Department.
The AHTD suggests that spectators view the demolition from the Little Rock side of the Arkansas River, although officials suggest the entertainment value of this likely will be low.
By Thanksgiving, Kansas City-based Massman Construction will be 55 days into the 180-day period the company included as part of its $98.4 million bid to replace the Broadway Bridge.
As you watch the construction this week, remember how far we’ve come:
