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 while also working on California and Nevada. While doing all that, I managed to drive and photograph at least a little bit in most of these United States.

As of October 2018, I’ve finally finished Oregon. I started on California and Nevada in earnest in October 2017 and am well underway and on track to finish those states by 2020. I’ve begun also clinching Utah in 2020 – my remaining CA/NV clinching trips all require three day weekends, but that’s no reason I can’t get started on Utah for now, pending the end of the world with this coronavirus thing. I’m planning to also get started on Colorado and New Mexico in 2021 to finish out the west.
