This morning I tried a new commuting route - I used a bus bike rack to get my bike to the Pentagon, and rode to Rosslyn via Arlington Cemetery, the MUP that goes past the Netherlands Carillon, and N. Meade St. According to the Arlington Bike map, there is a MUP that parallels Jefferson Davis Highway (Rt. 110) from Rt. 27 to the Arlington Cemetary Metro station. The only path I saw was an extra wide shoulder on Rt 110. Is that it? Or did I miss something - like is the MUP on the other side of the Metro tracks? It was okay on the shoulder, but thats not a bike path.
