A two-car accident injured three people, including a 73-year-old man seriously, and forced the temporary closure Tuesday of Jericho Turnpike in Elwood, police said.

A Jeep Liberty driving westbound on Jericho near Eldorado Drive at about 10:15 a.m. collided with another vehicle, driven by a man, 73, a police spokeswoman said.
