Following US 1, I-95 enters the city of Bridgeport, which is the largest city in the state of Connecticut. On the city's West Side, the freeway has an interchange with Route 130, where it becomes elevated and gains a fourth southbound lane, as it passes through the industrial areas of the city's southwestern neighborhoods. Within that interchange, the road also crosses the New Haven Line. Further within the area, I-95 crosses over the New Haven Line again and passes to the south of downtown Bridgeport. Here, the freeway provides access to many of the city's major landmarks in the South End and downtown area, and meets the combined southern termini of Route 25 and Route 8, which both head north from I-95 as a single five-lane freeway. From this point, the road narrows to three lanes in the southbound direction, and comes onto to the P.T. Barnum Bridge which carries it over the New Haven Line, adjacent to the Bridgeport station, and the Pequonnock River. On the bridge, the northbound direction gains a fourth lane, as it comes to an exit for Route 127 on Bridgeport's east side, after it passes over Route 130. I-95 reduces back to three lanes in the northbound direction, as it curves into the city's East End, where there is another interchange for Route 130. A short distance later, the freeway reaches an exit to Route 113 on the border of Stratford, providing access to the Sikorsky Memorial Airport. Afterward, the road passes by downtown Stratford and heads into a commercial area, where it has an exit serving US 1 and the southern terminus of Route 110, before crossing the Housatonic River on the Moses Wheeler Bridge.
