Agree with rcannon – biking to Nats games is a great way to go, and the bike valet is awesome. I usually tip the two guys $1-2/bike. The valet is on the east side of the ballpark, near N St. and 1st St. SE.
Maine Ave/Water St. from the Fish Market to about 7th is kind of a mess right now due to construction. If you’re brave you can take the lane on Maine, but I’d recommend avoiding it Maine and M St altogether on a game day. Here are a few ways I’d do it:
Carefully take the sidewalk on Maine, then hang a left on 7th to the I St. bike lanes.
Or, take the Case Bridge switchback-y path from the Hains Point Park Service lot. Ride on the sidewalk for a couple blocks to get to I.
Avoid the whole mess by taking the long scenic route via the Mall.
