SAN FRANCISCO — I can now say that I have been at both ends of Interstate 80. We jumped on it from US 101 at its western terminus for our brief jaunt to Treasure Island. I have been to the eastern terminus at I-95 in New Jersey several times. By the way, I think the eastern terminus needs to be somewhere in New York City, so that it can cross the George Washington Bridge. It would be fitting to have to big bridges on opposite ends of the road.
I-80 is easily the longest interstate that I have seen from both ends. The next longest is probably I-78, though I may have been to both ends of I-87, I can’t say for sure. I’ve passed both ends of I-84, but I wasn’t on the eastern end, I was on I-90 (Mass Pike). I have been on all of I-66 and I-68 too.
I-80′s current terminus was once the end of US 40 and US 50 until 1964, when California wiped out most of its US routes to avoid duplication with interstate highways. I can understand getting rid of US 40 since there is an I-40 in Southern California, but would it have been so bad to keep US 50 as a sea-to-sea route? I have been to the eastern end in Ocean City, Md. Additionally, extending US 50 back to San Francisco would mean that US 50 was routed over a Bay Bridge twice since there is the William Preston Lane Jr. (Chesapeake Bay) Bridge in Maryland. One of the spans of that cross is even the same X truss style as San Francisco’s Bay Bridge.
