The crowd in Philly for the NFL Draft could be massive — somewhere in the neighborhood of 200,000 people — and the city’s prepping the rollout of street closures and other changes ahead of the large event on the Parkway from April 27 to 29.

Here’s what we know about road closures and how this will impact transit, cycling, pedestrians and more:

How and when the roads will close

The city says a “full set of road closures” will be implemented at 12:01 a.m. on Tuesday, April 25, and the “the full extent of these closures” will be in place through 5 a.m. on Monday, May 1. There are several phases of road closures, but delays can be expected throughout Center City and the immediate area around the Parkway throughout the week and into the weekend. Drivers are encouraged to use other routes and refrain from double parking “which creates congestion, limits traffic flow and is illegal.”

Here’s a GIF showing what the road closures will look like (and you can find the full traffic plan at the end of this article):

What it means for pedestrians and cyclists

Bike lanes and sidewalks along the Parkway, in the Eakins Oval area and near the Art Museum will be detoured while venue construction is underway. The city says “appropriate signage” will be displayed, and both cyclists and pedestrians are advised to use detours as marked. The primary north-south pedestrian detours will be 22nd Street and Anne d’Harnoncourt Drive.

What it means for public transit

SEPTA hasn’t yet announced changes for the Draft, but you can follow along with service changes at their website: www.septa.org or by calling Customer Service at 215-580-7800.

The Broad Street Line will likely be the place to be, though. The Philadelphia Convention and Visitors Bureau has secured free parking down at the stadiums for people attending the “NFL Draft Experience.” That means the BSL will be crammed with people heading back and forth between the stadiums and the Parkway.

The PHLASH Downtown Loop is also adding services for Thursday, April 27 and will operate on an April weekend scheduled Friday to Sunday that weekend. PHLASH will communicate detours at http://RidePhillyPHLASH.com.

If you feel the need to drive into Center City, the city says off-street parking lots and garages will be available. Visit www.philapark.org for a list of options.

The fan ‘experience’ you can be part of

The NFL is inviting fans to come to a three-day “football festival” held along the Parkway from Thursday, April 27 to Saturday, April 29. Admission is free! There will be “interactive exhibits, immersive games, and virtual reality experiences, free player autograph sessions and more” from noon to 11 p.m. each day.

The city also noted most of the cultural institutions along the Parkway will remain open throughout the NFL Draft and some of them, including the Franklin Institute, will offer specials.
