DALLAS (CBSDFW.COM) – The City of Dallas has issued a traffic alert, but some are saying that it came too late.

City officials apologized after complaints on Tuesday, saying they underestimated the impact the production would have on commuters. Wednesday morning drivers found extra police downtown, all helping with traffic control.

The City also tried to avoid some of the rush hour hassle from Tuesday by delaying set up. Dallas police officers pushed back setting up barricades until 9 a.m. Wednesday morning.

Filming is underway for a new miniseries, but the timing is impacting thousands of commuters. The miniseries is called “11/22/63” and it is based on a Stephen King book. The project stars James Franco and will air exclusively on the Hulu video streaming service.

The miniseries is about a teacher who travels back in time to stop the assassination of President John F. Kennedy. Production started on Tuesday in Dealey Plaza, and continues today, shutting down some major downtown Dallas streets.

Many fans fought to get a glimpse of Franco while he worked on his scenes. But, when you add in the thousands of commuters who normally pour into downtown Dallas from the west side, the Dealey Plaza area quickly became far more congested than a typical day.

Some people were upset with the traffic situation, but others felt lucky to witness the TV production. “I thought it was a pretty cool experience seeing all the classic cars driving around and all the actors in their clothes,” said visitor Vanessa Ricardi, who was in town from Seattle. “It was pretty fun.”

Drivers can expect the same thing (onlookers and traffic) on Wednesday, and then again Thursday. But, extra police officers will again be helping with the traffic problems, directing drivers around the mess. City spokeswoman Sana Syed said, “We apologize to drivers for the inconvenience they have experienced. While the next few days won’t be painless, we are increasing police presence to help with traffic.”
