East Side. The expressway was one of the first to use air rights over a major highway. After completion of the expressway, the George Washington Bridge Bus Station was built. After purchasing the air rights in 1961, Marvin Kratter built four highrise apartment buildings, known as the Bridge Apartments, over the expressway. The 32-story buildings are among the first aluminum-sheathed highrise structures built in the world. Local traffic reporters frequently refer to congestion "under the Apartments" during morning and evening rush hours. Exit numbers The first change to exit numbers along the New England Thruway section of I-95 was in April 1980 when the section was converted for sequential exits. Prior to the change, the Cross Bronx Expressway and New England Thruway sections had different exit numbering systems. More specifically, exit 19 on the Cross Bronx Expressway was followed immediately by exit 2 on the New England Thruway. As a result, because exit numbers on I-95 repeated themselves in close succession, the old exit numbering system frequently caused confusion. As part of an experiment, I-95 was one of the few roads in New York to receive mileage-based exit numbers. This was implemented over both the PANYNJ section and the New York State Department of Transportation (NYSDOT) section of the highway (exits 1A–8C). The thruway section (which had originally carried its own sequential exit numbers) was then renumbered by the NYSTA to a system of sequential numbers starting from 9 (where the mileage-based system left off). This led to a situation in which exits 1 through 8 were mileage-based (all but one of which contained lettered suffixes as a result) and exits 9 through 22 were sequential. Around 2005, NYSDOT began a project to renumber I-95 with sequential numbers throughout. However, the idea never fully got traction with all three agencies. The PANYNJ did complete the renumbering on its section of the road. NYSDOT itself renumbered only one section of the road in Parkchester. Meanwhile, the NYSTA did not renumber any of the exits on its stretch of the road. This led to a situation from 2005 through 2012 in which some exits were signed with two different numbers, while some numbers were repeated twice, but only on some of the signs. Finally, in 2012, NYSDOT restored the mileage-based numbers to its portion of the highway, which once again line up with the thruway portion. This has eliminated all of the
