(AP) — Two processions of cars are setting out this weekend from New York and San Francisco to the midpoint of Kearney, Neb., to celebrate one of the nation’s first transcontinental highways.

History buffs, road-trippers and auto-lovers alike are marking the 100th year of the coast-to-coast Lincoln Highway.

The two-day Centennial Celebration in Kearney begins June 30 with the arrival of the antique cars in downtown Kearney. On July 1 — the day the Lincoln Highway was incorporated in 1913 — the celebration moves to the Great Platte River Road Archway at Kearney that spans Interstate 80.

Lincoln Highway Centennial co-chairwoman Sarah Focke says organizers are expecting some 300 cars and more than 5,000 people — some from Russia, Germany and England — for the celebration.
