Post 2 – This bridge crosses 495. My experience with commuting is atypical. I don’t think I have driven to work in Washington more than a dozen times in more than thirty years.
I mostly share the trail with runners and a lot of women pushing baby carriages.
Next is crossing Lee Highway. The most dangerous are people making right turns. MOST drivers are respectful of bikes. Things have improved a lot. There are more bikes now and drivers are better behaved, but you still need to watch.
