Fort Worth: Panther Island bridge progress update
The three TxDOT signature bridges under construction on White Settlement Road, North Main Street and Henderson Street have seen lots of progress recently.
Eighteen of the 20 V-piers have been completed, and concrete is being poured for the support for the White Settlement roadway.
White Settlement Road Bridge. TxDOT’s contractor has completed pouring all eight of the signature V-piers. Workers have proceeded to the bridge deck and are pouring the lower portion of the White Settlement bridge deck that supports the roadway.
North Main Street Bridge. TxDOT’s contractor has completed all four of the V-piers on North Main Street, as well as recently installing all of the steel to support the falsework for the deck of the bridge. The contractor has started the support for the steel cages that are needed to begin pouring concrete for the roadway. In addition, the north and south approaches to the bridge have been paved.
Henderson Street Bridge. The contractor has poured six of the eight V-piers on the bridge and has installed reinforced steel on two remaining V-piers.
To pour each V-pier, approximately 210 cubic yards of high-strength concrete is placed over a 12- to 14-hour period. Due to the warmer summer weather, the work is performed during the very early hours of the morning. Liquid nitrogen is being used to help control the temperature of the concrete being placed.
