After turning east towards Bethlehem, it terminates at I-70 in West Virginia near Elm Grove. The freeway was built between 1975 and 1983. On average, between 25,500 and 37,840 vehicles use the highway daily. The West Virginia portion of I-470 has been named the USS West Virginia Memorial Highway since December 2000, commemorating the attack on Pearl Harbor. (Full article...)
