 I-676 begins at an interchange with the Schuylkill Expressway (I-76 and US 30) in Philadelphia, Pennsylvania, heading to the east on the six-lane Vine Street Expressway concurrent with US 30. It immediately crosses the Schuylkill River on the Vine Street Expressway Bridge and comes to an interchange with 23rd Street and 22nd Street and the Ben Franklin Parkway that has access to the Philadelphia Museum of Art and the Franklin Institute. From this point, the Vine Street Expressway enters a depressed road cut and passes under several streets, running along the northern edge of Center City Philadelphia. Vine Street serves as a frontage road to the freeway at street level. Within this alignment, there is an exit for PA 611 (Broad Street). After passing under 10th Street in Chinatown, the last street the depressed alignment passes under, the highway rises up and reaches a split between the Vine Street Expressway, which continues to I-95, and I-676 / US 30. At this split, there is also an eastbound exit and westbound entrance for 8th Street. After exiting the Vine Street Expressway, eastbound I-676 / US 30 has a brief at-grade portion along southbound 6th Street to the Ben Franklin Bridge approach, an example of a non – limited access section of Interstate Highway. Westbound I-676 / US 30 has a ramp from the bridge to the Vine Street Expressway that intersects 7th Street and 8th Street at-grade. From this point, I-676 / US 30 crosses over the Delaware River on the seven-lane Ben Franklin Bridge, which also carries pedestrians and the PATCO Speedline. This bridge and its approaches are maintained by the Delaware River Port Authority.
