Arlington has two streetcar projects in planning. Columbia Pike has been in the works longer and received more press, but Crystal City is no less important. When they’re both up and running, they’ll most likely operate as a single line.
One key difference between them is that the Crystal City line will run in its own right-of-way, meaning it won’t have to share lanes with cars. Much of its transitway is already in place, and will open as a BRT line before the streetcar is ready.
Here’s the first rendering of streetcars in Crystal City, released in the project’s November newsletter.
