[Boiler Plate]

Bike Lanes! Seriously? It’s an Interstate Highway. It is illegal to ride a bike or anything else that can’t travel at least 45mph.

Slow down and rethink that. Nobody is going to ride a bike on the interstate highway. But it's a very simple thing to put a separated bike lane/wide sidewalk along the outside edge of the bridge. On both sides of the river this would connect to bike friendly streets or bike paths via access ramps. Take a look at the Woodrow Wilson bridge as an example. (If you don't know DC, that's the downstream beltway bridge.) In DC, all the Potomac and Anacostia river bridges have walkable/bikeable sidewalks connecting to pedestrian/bike infrastructure on both ends. Except for 695, which is just an interstate connector and doesn't need a sidewalk because it is directly alongside the 11th street bridge, which is multimodal. Bridges are expensive. Maximize functionality. Putting a wide sidewalk on them solves a lot of problems.

DC is way ahead of the suburbs on this. We have too many suburbs built on the assumption that people will get into their cars to cross the street, that no one would ever walk anywhere, and that bicycling should require loading your bikes onto a car to go find a park with a bike path.

The multi-use path on the Wilson Bridge is separated from the traffic by a tall, thick see-through screen of glass or some even better material, so that the cyclists and joggers will be safe, while drivers still get to enjoy the view.
