 On November 26, 2008, a Pennsylvania General Assembly act designated the section of PA 73 along Cottman Avenue between Central Avenue and Algon Avenue in Northeast Philadelphia the Police Sergeant Stephen Liczbinski Memorial Highway in honor of an officer of the Philadelphia Police Department who was killed in the line of duty; signs were installed in 2012.In 2009, a $212.3 million project began to reconstruct the interchange between PA 73 and I-95 as part of rebuilding the stretch of I-95 through Northeast Philadelphia.The first phase of the project relocated the ramp to southbound I-95 from Princeton Avenue to Longshore Street, converted Princeton Avenue and Cottman Avenue to two-way traffic, reconstructed and widened State Road at the interchange, and added an on-ramp spur from Milnor Street to the ramp from Princeton Avenue to northbound I-95.
