2026 Update- Over the last couple years I’ve gotten married and had a baby, so I’m not devoting as much time to this as I did in the past – but there is still content trickling in! I’m actively working on clinching VT/NH/ME, but at a much slower clip than in the past. I also have tens of thousands of photos in a backlog from other states throughout the country that I’m working on getting up as time allows.

Welcome to Corcohighways.org, a one-man show dedicated to driving and photographing as many of the nation’s highways as possible.

Back in 2007, as a college freshman with a love of highways and a car that needed driving, I embarked to drive every mile of state highway in Washington. At that point, a monster was born. In 2009 I moved to Wyoming and clinched that system. In 2011 I moved to Arizona and clinched that system. In 2013, I moved to Montana and finally clinched the Idaho system in 2014. In 2015, I went to Delaware just to clinch that highway system. In 2016, I finished Montana and moved to Idaho, allowing me to get started on Oregon. In 2018, I finished Oregon. In 2020, I finished California and Nevada. In 2021, I made the big relocation to the northeast – and finished Connecticut, Rhode Island, and Massachusetts by 2024. While doing all that, I managed to drive and photograph at least a little bit in most of these United States.
