Abstract:

The three-cable barrier on I-5 between Salem and Wilsonville is still providing for safe travel by preventing median crossover crashes. 35.2 km (21.9 miles) of three-cable barrier is in place. In December 1996, 14.5 km (9.0 miles) of the barrier was installed. Another 20.7 km (12.9 miles) was installed by April 1998.

The cable system is recommended for use in locations where there is enough room for lateral deflections of up to 3.5 m (11.5 ft). The width of the median needs to be at least 7 m (23 ft) for a cable system centered in the median. Cable systems should not be used on sharp curves or where curbs exist or in areas where it is likely to be hit frequently.

Although cable barrier installation costs are less than concrete, maintenance and repair costs for cable barrier are higher. Appropriate budget increases should take place for the agency charged with system maintenance.
