If you are a f
requent bridge traveler, you've likely noticed the recent daytime lane closures. These closures involve shutting down one lane of the bridge in each direction for the installation of digital stress monitors. The closures are scheduled to last until approximately May 2008.
CTL Group, a Skokie, Ill. based firm, is about 800 digital and static strain gauges to keep a close eye on how the bridge will react to structural changes of the truss widening. The CTL Group specializes in structural monitoring, nondestructive testing and evaluation and repair of bridges worldwide. The gauges will transmit data to engineers until project completion in 2013.
See below for photos and captions of the strain gauge installation.
Unfortunately, lane closures are inevitable. Safety is a priority – for our contractors, the bridge and motorists. All lane closure notices are subject to change.
When planning your commute, keep in mind the most current lane closure information is available by calling our 24/7 public outreach automated phone line at (504) 731-4200. We keep the website, www.hueypbridge.com, updated as well. Also pay attention to the digital roadside lane closure signs.
The Crescent City Connection and the Hale Boggs Bridge are alternate routes.
NOTE: There will be no lane closures on the bridge from March 24 to 29 to accommodate for Zurich Classic of New Orleans golf tournament traffic.
