Police in Charlottetown are advising drivers to plan ahead before trying to park downtown today for the Shania Twain concert.

More than 20,000 people are expected at the Charlottetown event grounds Saturday evening.

Deputy police chief Richard Collins says a little planning will help alleviate a lot of driving and parking headaches.

“We encourage people to carpool. We encourage people to walk to the site if they can. There will be a certain number of road closures and restrictions. We're asking people to visit our website to see all those restrictions," he said.

"We're encouraging people for a drop off site to go to the [Workers' Compensation Board] parking lot on Williams Street. That will be a drop off site for people who wish to walk to the site."

Police say extra officers will patrol the downtown throughout the day and after the concert ends later tonight.

The gates open at 4:30 p.m. AT.

Twain is on the Island. She tweeted a photo of her view in Charlottetown Friday night.
