In March it was announced that the Sherman Avenue Streetscape project would be receiving federal stimulus funds. While the start of construction is not set to begin until 2010, the DC Department of Transportation has released new details about the project:
The current design recommends road repaving, field surveys, roadway design, landscaping, new tree planted median, street lighting, traffic signals, pavement markings, signing, and modifications to on-street parking and safety improvements for both vehicular and pedestrian traffic.
This information and more is available in the presentation presented at the Sherman Avenue Streetscape working group earlier this month: http://ddot.dc.gov/ddot/frames.asp?doc=/ddot/lib/ddot/majorinitiatives/sherman-ave/design/materials/2009-05_presentation.pdf
Greater Greater DC also has a, well, great photo of Columbia Ave. and Sherman Ave. then and now.
