SANTA FE — New Mexico marked the 80th anniversary of the Trinity Test with the dedication of a new roadside sign honoring the Trinity Downwinders affected by the blast. 

A public dedication ceremony was held Wednesday at the intersection of U.S. Highway 380 and N.M. 525 to unveil the sign and mark the 80th anniversary of the Trinity Test.
