Philly's Independence Day Parade route cut short due to extreme heat

The city of Philadelphia is getting ready for the events planned to celebrate the country's 250th anniversary even as extreme heat forces some changes in plans.

Inside the Pennsylvania Convention Center on Monday, crews were hard at work putting the finishing touches on the floats for "The Salute to Independence Semiquincentennial Parade."

Philly's Independence Day Parade route cut short due to extreme heat

This year, the route was supposed to be expanded. It was set to take the floats, 42 marching bands, and other performers down the parkway to Logan Circle.

"The reality is that Mother Nature is Mother Nature," Todd Marcocci, the parade producer, told Action News. "From the get-go, in designing the original route, I had escape plans, shall we say."

Marcocci said the parade will now start at 5th and Chestnut, pass by Independence Hall, head up Market Street to City Hall, and end at Broad and Chestnut.

"The magic will still be well alive on the parade route," Marcocci said. "The tapestry of independence comes to life in this parade."
