* The Navy Yard alerts folks that the 11th & O gate to their part of the Riverwalk will be closed for approximately three weeks because of demolition work on the old outbound 11th Street Bridge. (This means that the Navy Yard Riverwalk itself isn't closed, it just means you can only access it west of 11th Street.)

* Speaking of the old bridge, City Paper writes that this demolition doesn't mean the end of the "recreation bridge across the Anacostia" idea, just that it was determined that it would be better to take off the old bridge deck than to try to maintain it while working on the recreation bridge idea, which will still need financial backing even after the design competition is held this fall.

* Speaking of the river, DDOT has launched AnacostiaWaterfront.org as a new online home for information on projects along the river, such as the 11th Street Bridges, the planned new South Capitol Street Bridge and associated corridor upgrades, the Riverwalk, and other projects.

* One tidbit unearthed in the new web site: An environmental assessment is expected to start this fall on reconstructing Barney Circle and transforming the "easternmost dead-end section of the Southeast/Southwest Freeway into a boulevard between the circle and 11th Street, SE."

(As always, follow JDLand on Twitter or Facebook if you want quicker access to these types of tidbits, most of which I sent out over the past week or so.)

First, a few new entries in the What's New Around the Ballpark? lineup:

* On Tap Magazine surveys the neighborhood with "The Hidden Gem That is the Capitol Riverfront." (Another jewelry metaphor to go with the Post's "Diamond in the Rough" piece from Sunday.)

* WJLA wandered around looking at the ballpark environs.

* The Post's Going Out Gurus blog checked out the Fairgrounds' sneak peek on Tuesday. (Though what's the deal with the photos that look like they were taken through a veil? Will this Instagram obsession never ebb?)

* WTOP runs down the options for arriving at the ballpark by water taxi. (American River Taxi, by the way, says that they are almost sold out for the April 12 home opener.)

Some other items:

* Two reports from MLB.com on the Wounded Warrior Amputee charity softball classic, played Tuesday after the Nats-Red Sox exhibition. The Warriors pounded their celebrity challengers 17-4.

* "DC Modern Luxury" magazine's Men's issue picks the Foundry Lofts as one of the city's "Best Bachelor Buildings." Go here, then click on the Best Bachelor Buildings subhed to get to page 62, then look at the bottom of the page. (As an aside, the write-up sounds even better if you imagine it being spoken by Stefon.)

* Or, if you like your tidbits a bit less glossy, Multihousing News has "Foundry Lofts Blazes Trail on DC Riverfront."

* Bluejacket gets a big write-up and cover photo in Beer Advocate magazine, though we don't get to read it online. You'll just have to make do with the Sept. 2011 batch of photos from inside the Boilermaker Shops the brewery has put up on their Facebook page.

* Nineteen "experts" have picked the Nationals to make the playoffs this year. No pressure!

* The 11th Street Recreation Bridge meeting happened while I was out of town, but here's Greater Greater Washington's write-up of it. But, before the meeting, WCP's Alex Baca posted four thoughts about the concept, with some items of concern worth noting (though "it is a cool idea!" is the first bullet point).

* More Demolitions Coming: Raze permits have now been approved for the Miles Glass building at 8th and Virginia and its next-door neighbor, the closed auto repair shop at 7th and K. National Community Church, which owns the lots and others on the same block, said back in January that a temporary parking lot and "community green space" will be coming to the site while the church continues to work on its final plans for the site, which in the past have been described as being a combination of coffee house, performance space, and church offices.

* Yup, Navy Yard-Ballpark. The new Metro subway map is out, and confirms that Navy Yard-Ballpark is official.

* Bike to Work: May 18 is DC's Bike to Work Day. One of the pit stops is the Yards Park, from 7 to 9 am, and you get a t-shirt if you register and then stop at your designated pit stop.

* Bridge Recreation: If the notion of the "11th Street Recreation Bridge" captured your fancy, you can see some additional stories on the idea by Lydia DePillis, BeyondDC, and WJLA. DePillis notes that the city isn't intending on paying for this entire thing itself, and a decision needs to be made by May whether or not the new 11th Street Local bridge will have the bulb-out viewpoints built (they'd be unnecessary if the current downstream bridge was being kept). WJLA, on the other hand, mentions that "some" are concerned it "could become a hotbed for crime"--which led to a fun Twitter back-and-forth that devolved into using the new bridge for a Jason Bourne/James Bond-type chase sequence.

* Mobile 'Hood: The Capitol Riverfront BID has launched a mobile version of its web site, which uses your phone's GPS to give you information on food, developments, and events near your location.

And, of course, if you want to know what your current location looked like before all the changes started happening, you can go to my mobile site (m.jdland.com) or jdland.com/here on your phone and you'll get my oldest photos looking in each direction from the corner nearest to where you're standing. (Read more about how that works.)

* Fairgrounds: DCMud looks at the plans for the Half Street Fairgrounds (which I broke the news of back in February), with a few neat new renderings. And then the piece drops a mention at the very end that "DCRE Real Estate" is handling the retail leasing for the project--that's DCMud's company, and the writer of the blog post is also the agent handling the leasing. (Just in case you like to be aware of those sorts of things when getting your news.) In the meantime, a few shipping containers were spotted on the site last week.

* Across the Way: A 5,000-seat concert hall is being designed for the Southwest Waterfront. (If you haven't been keeping up with the plans for The Wharf, SWill can help.) And the de-skinning of the old EPA buildings, visible from parts of Near Southeast, is part of their rehabilitation into the Sky House apartments.
