the Schuylkill River Trail and CSX Transportation's Philadelphia Subdivision railroad line on the river's east bank on the Vine Street Expressway Bridge, before coming to an interchange with 23rd Street and 22nd Street and the Benjamin Franklin Parkway that has access to the Philadelphia Museum of Art and the Franklin Institute science museum. 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. Vine Street serves as a street-level frontage road to the freeway. Within this alignment, there is an exit for Pennsylvania Route 611 (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 Benjamin 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 I-95, Christopher Columbus Boulevard, and then the Delaware River on the seven-lane Benjamin Franklin Bridge, which also carries pedestrians and the PATCO Speedline. This bridge and its approaches are maintained by the Delaware River Port Authority (DRPA). New Jersey After crossing the bridge, the freeway enters the downtown area of the city of Camden in Camden County, New Jersey, and passes to the north of the former site of Campbell's Field, a former baseball stadium. Upon entering New Jersey, I-676 becomes signed as a north–south road. There is a southbound ramp to 6th Street in Camden, which is near the toll plaza for northbound traffic. After the toll plaza, US 30 splits from I-676 at an interchange, at which point I-676 turns south as a six-lane freeway called the Martin Luther King Memorial Highway or the North–South Freeway. Immediately after the US 30 split, there is an interchange with County Route 537 (CR 537; Market Street/Federal Street) and Martin Luther King Boulevard that provides access to downtown Camden. Within this interchange, the highway passes over NJ Transit's River Line. From this point, I-676
