Philadelphia Marathon weekend kicks off Friday as a good portion of 30,000 registered runners head to the Pennsylvania Convention Center to pick up bibs and attend the health and fitness expo.
But this year marks the first time two separate race days will be held. And that means two days of road closures.
Previously, the full 26.2 mile marathon, the 13.1 mile half marathon and the Rothman Institute 8K, were held simultaneously on Sundays. This year, for the 23rd year of the race, the half marathon and 8K are on Saturday, along with a kids' run. The full marathon is on Sunday.
In all, 60,000 spectators and 3,000 volunteers are expected.
The city advises motorists to use mass transit for find alternate routes. Streets close on a rolling basis.
Here are key areas impacted:
Here's a detailed breakdown:
Outer lanes of the Parkway close from 9:30 a.m. Lanes reopen 3:30 p.m. for the afternoon rush hour.
For the Half Marathon, due to enhanced security, City of Philadelphia "no-parking" regulations will be enforced strictly and all vehicles on the race route will be relocated, beginning at 2 a.m.
Call the Philadelphia Parking Authority at 215-683-9550 for more information.
Street closures go into effect 2 a.m. until 3 p.m. along the Benjamin Franklin Parkway, between 20th to 25th Streets, and also on Kelly Drive, Martin Luther King Drive, and numerous other roads in Center City (see complete list below).
Best bet is to stay away from Logan Circle and anywhere near 18th and Parkway, both closed to traffic until 11:30 a.m.
Other streets affected Saturday:
Streets open by 2 p.m. if they have not opened already after runners have cleared the route.
Again, "no-parking" regulations go into effect. All vehicles on the route will be relocated starting at 2 a.m. In addition, the Parkway, from 20th to 25th Streets, closes 2 a.m. to 4 p.m. Streets along the race course open after they are cleaned.
