Yesterday, someone asked me how to get to the 14th Street Bridge's active transportation lane (ATL) without using the snow and ice covered Mt. Vernon Trail (MVT), and I realized you can't. Same goes for the TR Bridge and Memorial Bridge. Having the CCT or Rock Creek Park Trails basically closed might be inconvenient, but there are, at least, on road alternatives. But you can't just hop on I-495 or the GW Parkway if the trail isn't safe. The only place you safely and legally really cross the Potomac without using the trails is the Key Bridge.
Richard Layman wrote recently about treating some sidewalks as snow emergency routes because they approached schools or hospitals. So, where are the key pieces of bike infrastructure that can't be replaced? The pieces that should be treated like snow emergency routes and cleared?
Here are some I identified (and they're all bridge related)
1. The ATL for the Wilson, 14th Street, Roosevelt, South Capitol, 11th Street and East Capitol Bridges.
2. The MVT from the Crystal City Tunnel to 14th Street Bridge.
3. The MVT from N. Lynn to the TR Bridge
4. The Washington Boulevard trail from the Pentagon to Memorial Bridge
5. The C&O Canal towpath from Chain Bridge to the CCT and from that point on the CCT into Georgetown.
What did I miss?
