A man who was found dead this afternoon near an on-ramp to northbound Interstate Highway 680 in San Jose appears to have been a transient who died of natural causes, a California Highway Patrol spokesman said.

The CHP received a report of a man lying near a chain-link fence along the Alum Rock Avenue on-ramp at 2:22 p.m.

The man, who appears to be in his 40s, did not have any signs of trauma, CHP Officer D.J. Sarabia said.

It does not appear any vehicles were involved in his death.

Authorities said the man had been dead for some time.

He was found with his handheld radio still playing, Sarabia said.

The ramp was not shut down.
