Abstract:

The Penobscot-Narrows Bridge was constructed between May 2003 and December 2006. The bridge is a cable-stayed design with twin pylons and a 2,120-foot span. This cable-stayed bridge features a cradle stay system that

allows for each cable strand in the stay to span between the main-span bridge deck anchorage, through the pylon,

and then down to the back-span bridge deck anchorage. In each pylon, twenty stays run through individual cradle

systems with each stay enclosed in a high-density polyethylene (HDPE) sheathing extending from the pylon to the

bridge deck.

The unique design features of the cable support and anchorage systems used in the Penobscot-Narrows Bridge not

only permit the replacement of each cable strand, but also present engineers with the opportunity to test a variety of

cable designs and materials for their longevity and performance in order to better serve the entire bridge industry.

The engineers at MaineDOT recognized this, so in June 2007, two steel strands were removed from each stay, at

stay numbers 2, 10 and 17 of the Prospect side pylon, while concurrently installing two carbon-fiber composite

cables (CFCC) in their place.

This report provides data and analysis of the CFCC cables from the installed structural monitoring system and

makes recommendations for long term monitoring of the cables.

A previous report documented the CFCC installation, instrumentation and initial data analysis
