[Talk-us] Combined parking/bike lanes

[John F. Eldredge]

One thing that is an issue with many of the marked bike lanes in 
Nashville, TN is that they aren't contiguous.  You will come to a point 
where the road narrows, such as for a bridge, and the bikes are forced 
to share a lane with motor traffic.  This makes bike riding at rush hour 
a risky activity.
