**UPDATE March 2022: No, I’m not dead. I apologize for the lack of content in 2021; it was a very busy year. I moved to Connecticut and am working on clinching its highways and generally driving all around the east. I have a massive backlog of content that I’m finally starting to catch up on, and am ready to resume adding new items to Corcohighways. I’m planning to take east coast states one at a time – and do still intend to eventually finish Colorado and Utah, though the timetable on that may be somewhat delayed. I can’t promise that this site will continue to be as active as it was in earlier years, as life has gotten busier and more important priorities have taken time, but I do want to continue churning out new content if at a snail’s pace. Thanks for your patience. ***


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. While doing all that, I managed to drive and photograph at least a little bit in most of these United States.
