Rail Cracks

20 miles of concrete bridge and 21 large elevated stations will come with many construction problems. It is surprising however that large problems have developed in the first two miles of the guideway of Honolulu's elevated rail.

"There is evidence for concern at this point. There are some obvious failures," said Panos Prevedouros, a frequent rail critic and a University of Hawaii civil engineering professor.

Large-sized cracks are not normal, only hairline cracks are acceptable in concrete,” said University of Hawaii engineering professor Panos Prevedouros.
