PITTSBURGH (KDKA) – The “American Idol” audition process begins Wednesday morning at Heinz Field, and it could affect your commute to work and where you park.

As many as 30,000 people are expected for the Pittsburgh auditions.

Pittsburgh is the only audition site on the upper East Coast, which means people are traveling from considerable distances to be here.

A two-day registration begins Wednesday at 7 a.m. The actual auditions will be under tents set up on the field on Friday.

Parking lots will open at midnight Wednesday, and although there are rules about camping out, a line is expected to form outside the entrance at some point overnight.

Pittsburgh Police are warning drivers of an expected increase in traffic and particularly pedestrian traffic on the North Shore.

Spokesperson Diane Richard is recommending people carpool, get dropped off or park in lots farther away on the outskirts of town.

She also said drivers should pack some patience.

While people are heading into town from all over, Anita Little and her daughter, Carly, are from Peters Township, but chose to stay at hotel on the North Shore to make sure Carly got to the audition without any problems.

The judges on the show will not be here. Instead, people will audition for producers with a lucky few being asked back to eventually meet the judges of the program.
