Welcome to the District Department of Transportation's (DDOT for short) online photo archive called DDOT Back In Time. Here you'll find photographs chronicling DCs transportation history, including transit, streets, bridges, construction, bikes, pedestrians, and more. 

This archive is under construction. We have thousands of photos in our collection, as well as maps, newspaper clippings, and other historical items we are in the process of digitizing and adding to the site. So be on the look out for more. 

If you'd like to see even more of our collection, check out our Tumblr page at https://ddotdc.tumblr.com/ where we post weekly. You can also view the DDOT instagram page, where the library also contributes photos: https://www.instagram.com/ddotdc/

COVID-19 Update: Due to the circumstances surrounding COVID-19, the DDOT library is currently closed to visitors. However, please let us know if you need help searching our online collections! The librarian is available by email at kathleen.crabb@dc.gov.
