Road Trip - Future Interstate 99 From State College to I-80

An unique freeway linking State College with Interstate 80. This spur is short compared to others we've covered, but its an interesting look at one of the many proposed interstates that have yet to see full completion, hence its awkward end and transition to a two lane service road.

I-99 will be complete by fall of 2024 in Northern Pennsylvania, and it ends at I-86 in Corning New York. I-99 is a total of 210 miles in 2 states. 197 miles in Pennsylvania and 13 miles in New York. In New York, some freeways are changing its exit numbers to a mileage based system, and they did it at I-84 in Hudson Valley for 71.5 miles in New York, I-99 for 13 miles in New York, and 4 miles of I-781 in Watertown New York. Soon, it will change its exit numbers to a mileage based system along 190 miles of I-81 from Pennsylvania border to Canadian border, then followed by 116.64 miles of I-88 from I-81 in Binghamton to I-87 & I-90 (New York Thruway) near Albany for the exit numbers change.
