Custis Trail Tunnel

Rosslyn_now_4 There's a proposal before the Arlington County Board to build a 10-story, 43-unit residential building (for now called 1101 Lee Hwy) on the .61 acre site located east of North Lynn Street, between

the I-66 ramp and Martha Custis Bike and Pedestrian Trail to the south and the Key

Bridge/George Washington Memorial Parkway ramp to the north. The building would involve construction of a driveway across the Custis Trail. In order to mitigate the impact of the driveway on the trail, the building applicant has proposed modifying the intersection traffic lights to "signalize" the driveway.

But, in 2000, Rosslyn performed the Rosslyn Circle Crossing Study. It recommended that a tunnel be built under Lynn Street. The building is being scaled back considerably in height, density and access by the council and they've stated that the tunnel should be a part of it. The applicant's engineer did a preliminary study and determined that a tunnel with an alternative alignment would be possible but the suggested alignment has a curve that some feel might be dangerous.

At the December 2005 meeting they were still waiting on a response and deferred the subject to 2006. A bike/ped tunnel under Lynn would be a big improvement to a dangerous intersection.

Addendum: Please read the first comment to this post as it is very useful. I think I got some facts wrong. In my own defense they came from my own hazy memory and what I could glean from county council notes. If you can get through one page of those without falling asleep on your keyboard you are a better person than I.
