June 15, 2004: South end of IA 86 in Milford. I-90 is 23 miles north. Because 86 north of IA 9 wasn’t a state highway until 30 years ago, it has no shoulder and a wicked pair of curves at … Continue reading →

May 7, 2009: I-70 between I-270 and I-25. Notice the “Colo Spgs” in the background BGS for I-25. Also notice the wide numeral for US 6. US 85 has an independent route until it gets south of Denver and then … Continue reading →

August 2001: Rest area in between the lanes on I-84/US 30 in Oregon at Multnomah Falls in the Columbia River Valley.

July 1, 2009: North end of I-283 in Harrisburg, Pennsylvania. I-283 is the thru traffic while I-83 turns from east-west to north-south, to end at I-81 five miles north. I-283 cannot be clinched without getting onto the Pennsylvania Turnpike. This … Continue reading →

May 20, 2003: North end of IA 82 in the same place it had been for over 80 years, but would only stay for 40 more days. Blairstown, pop. 540 in 1920, got one of the original spur route, running … Continue reading →

May 9, 2009: North of York, Nebraska, on my way back from Denver. I took US 34 through about the central third of Nebraska. The 100-degrees-west line of longitude, which is still a ways west from here, is judged by … Continue reading →

June 24, 2009: South end of I-380. Notice each shield has the state name on it. This interchange also includes the rare sighting of Exit 0. But this page is for 80. I’ve been on it from its east end … Continue reading →

August 14, 2005: For an awkward time after the Second Great Decommissioning, Louisa and Des Moines counties tried this “neither-fish-nor-foul” naming convention. It was particularly odd in this case, when IA 79 had been J20 before 1980. All of this … Continue reading →

October 29, 2004: East end of IA 78 in Louisa County. The mileage sign in the background shows the distance to…nothing. Instead of covering up the top line, the “99” on the shield was removed when IA 99 was decommissioned.

June 12, 2005: North end of US 77 in Sioux City. It comes across the Missouri River and ends. Even at its greatest extent, though, 77 only went through Sioux City, and so IA 77 was never renumbered. Since Jason … Continue reading →
