What you need to know about driving on Interstate 95 during the DNC

Motorists on Interstate 95 during the Democratic National Convention should be prepared for weight restrictions and ramp closures.

Open to passenger vehicles

No vehicles weighing more than 5 tons

Vehicles that weigh more than five tons won't be permitted on I-95 between Exit 13 (for Interstate 76 West/Route 291/Valley Forge) and Exit 22 (for Interstate 676) between noon on July 23 and sometime midday on July 29, according to PennDot.

Commercial vehicles affected will include delivery trucks, utility vehicles, parcel trucks, buses, small dump trucks, buses, cement mixers, flatbed and stake trucks, box trucks and tractor-trailers, officials said. Personal mobile homes and recreational vehicles that weigh more than five tons also won't be permitted.

Detour routes

Transportation agencies "will utilize a combination of electronic message boards and stationary signs to guide commercial truck drivers along alternate routes during this temporary restriction," PennDot Secretary Leslie Richards said in a statement.

Here are the detour routes for the restricted vehicles, and authorities said drivers on these roads should be prepared for heavy traffic that's diverted off I-95:

From I-95 north: Route 291 (Penrose Avenue) east, to 26th Street, to Interstate 76 west, to Interstate 676 east

From I-95 south: I-676 west, to I-76 east, to 26th Street, to Route 291(Penrose Avenue) west.

No oversized loads

Oversized loads will be banned from traveling in the Philadelphia area from July 23 at noon until midday on July 29.

Ramp closures

Some intermittent ramp closures will take place during the convention.

- Northbound and southbound entrance ramps to I-95 between Exit 13 and Exit 22: Closed to vehicles weighing more than five tons

- Northbound exit ramp at Broad Street (Route 611/Exit 17): Closed from July 22 at 10 p.m. until midday on July 29

No construction and maintenance closures
