Abstract:

The Eklutna River/Glenn Highway bridge has sustained repeated impacts from overheight trucks. In 2006, ADOT&PF installed an ; overheight vehicle warning system. The system includes laser detectors, alarms, and message boards. Since installation, personnel have ; seen no new damage, and no sign that the alarm system has been triggered. Although this is good news, the particulars are a mystery: Is ; the system working? Is the presence of the equipment enough to deter drivers from gambling with a vehicle that might be over the ; height limit? Is it worth installing similar systems at other overpasses? This project is examining the bridge for any evidence of damage, ; and is fitting the system with a datalogger to record and video any events that trigger the warning system. Finally, just to be sure, ; researchers will test the system with (officially) overheight vehicles. Project results will help ADOT&PF determine if this system is ; functioning, and if a similar system installed at other bridges would be cost-effective.
