• Widening of the turning radius at Adams Mill Rd at Kenyon St and Irving St to allow vehicles to turn right without the risk of driving on the sidewalk
• Creation of sidewalk on west side of Irving Street
• 0.3 mile of roadway improvements with full depth asphalt pavement & milling and resurfacing of existing roadway
• 1900LF of water main replacement and 25 service connections, 27 new street lights and traffic signals, storm drainage upgrade
• Retaining Wall on Irving Street and Retaining Wall and Median Barrier on Adams Mill Road for grade separation with stone veneer
• Installation of new sidewalks, granite & concrete curbs, & concrete gutters
• Pedestrian safety fence and sidewalk widening at the bus stop to accommodate wheel chair accessibility

Project Significance

This project began with a transportation study in 2003 and was designed with input from the community and ANC1D group over many years. A complete environmental and historical review was undertaken. There were several changes made to the design features throughout the course of the contract and Fort Myer worked closely with DDOT to ensure that these changes were implemented into construction to mitigate cost and time impacts.
