An Oregon group is pushing city officials to put anti-suicide barriers on an arch bridge that has been the site of three suicides already this year.

The group, called Friends of The Vista Bridge, includes some who live and work near the majestic span west of downtown Portland.

Leaders are receptive to the idea of a security barrier, but the projected $2.5 million price tag is steep for a city that's been tackling a $20 million budget shortfall. The city may seek a federal grant.

"We certainly think of it as a high priority," City Commissioner Steve Novick said. "But there's a whole mess of competing priorities and not much money."

Other cities, in the U.S. and abroad, have erected barriers and seen a reduction in suicides from landmark bridges.
