Despite this abnormality, this is not the only area where the Turnpike has had an indirect interchange with an Interstate highway due to this funding glitch, although it is the only one where an Interstate highway has had to run onto a surface street. Interstate 79 in Cranberry Township; Interstate 81 near Carlisle; and Interstate 95 in Bristol Township have had, for decades, no direct connection to the mainline Turnpike, with I-79 relying on U.S. Route 19 to get onto the Turnpike and vice versa, while I-81 has had to rely on U.S. Route 11 for Turnpike access and vice versa, and I-95 had no access to the Turnpike at all. (Interstate 99, which relies on U.S. Route 220 for Turnpike access near Bedford, was only commissioned in 1998.) While direct access between I-79 and the Turnpike became possible in 2003 and another project to connect I-95 with the Turnpike opened in 2018, the indirect access in Carlisle remains.
