A military bomb squad Sunday destroyed eight unexploded Vietnam War-era bombs found by railroad workers replacing tracks in an area where a similar bomb was found two weeks ago.
There were no injuries or damage. The site was near an area where a trainload of bombs exploded 24 years ago in this suburb near Sacramento.
Sheriff's deputies evacuated 300 to 500 people from roughly the same 33 streets as two weeks ago, sheriff's spokesman Jim Cooper said.
A military bomb squad decided to blow up the bombs at the site individually, digging four separate holes and detonating the bombs in two batches, Cooper said.
Sgt. Martin Hutchings, a bomb expert, said the detonations went off smoothly, with the bombs exploding at varying levels of force.
The cluster of bombs was discovered Saturday afternoon. Six of the bombs were described in good condition. The other two were badly damaged by workers using earth-moving equipment.
Union Pacific voluntarily suspended construction in the area until today.
The U.S. Army Corps of Engineers may inspect the yard, and railroad and sheriff's officials will meet to decide any further action, Cooper said.
On April 28, 1973, a train carrying ammunition bound for the Vietnam War exploded in a daylong series of blasts. No one was killed.
