* Metro is expecting 24,000 fans to come via Metro for Opening Day (21,000 of them via the Navy Yard station), and 26,000 Mass attendees. They also expect 60 percent of baseball fans to arrive via Metro during the season.

* The Opening Day plan includes the newly enhanced N22 bus service, 18 extra pre-and post-game trains (mainly on the Green line), extra eight-car trains (perhaps up to every third train), and converting the Navy Yard Station to "one-way" traffic. (I presume this means for pedestrians, though I'm not sure if this means that *no one* can enter/exit the station against the flow before and after the game.) The fact that this first game is on a Sunday night is allowing Metro and the city to avoid a possible complete meltdown of the transportation network that might happen if it occurred during an evening rush-hour.

* Because Mass attendees must be through security and into the park by 9 a.m., Metro expects the largest crushes of travel to be between 5 and 8 am (the height of the morning rush hour) and again post-Mass. All available extra trains will be used when the Metrorail system opens at 5 am, and there will be 18 extra trains after the Mass ends. And, again, the document says that the Navy Yard Station will be converted to "one-way," which ought to be interesting for the commuters trying to use the station to get to and from work during this Thursday event. And the dreaded phrase "Rolling Street Closures" is mentioned for Pope Day, in that it might affect bus routes coming into the neighborhood. If there were ever a day for Near Southeast residents and workers to telecommute....

With the uncertainties about how fans and the transportation network will handle the crush of getting to the new ballpark for the first time, and with the president expected to throw out the first pitch, the Nationals are opening the gates at 3:30 pm on the 30th, 4 1/2 hours before the 8:05 pm start time. I've been told that they've acquired more than 50 magnetometers to try to lessen the burden of passing 41,000-plus fans through security, but if you're going to the game, you might not want to show up at 7:55.

UPDATE: For more, see this Tuesday entry on additional news on Metro's plans.

* A building permit has been approved to build a surface parking lot along First Street between M and N, where Normandie Liquors and its brethren were demolished last month. And the Archdiocese of Washington has applied for a public space permit for the 1300 block of First Street, SE--does the Popemobile need special parking permits?

* As plans at The Yards continue to move forward, there's now official names for the first-phase projects. Say hello to The Boilermaker Shop, The Pattern Shop Lofts, and Factory 202. (And 401 M and 400 Tingey, but those aren't anywhere near as catchy.)

* The 55 M web cam is no longer available to the public. Perhaps they want the Opening Day vista to be a big surprise. Or they don't want people watching the last-minute work on the Navy Yard Metro station. (I wonder if the gas main hit on Thursday was caught by this camera.)

* Some commenters are discussing the idea that's been floated of someday demolishing the Southeast-Southwest Freeway. Getting rid of this Berlin Wall that separates Capitol Hill and Near Southeast (and splits Southwest) was brought up in the National Capital Planning Commission's 1997 Extending the Legacy framework plan, if you want to see it actually on paper. (Apparently an updated NCPC framework plan is scheduled to come out this spring, which looks like it continues to have Virginia Avenue marked where the freeway currently is.) As to whether I'll see this done in my lifetime, well, it would be a nice surprise.

If you really want to go high-concept, you can read DDOT's 2003 South Capitol Street Gateway and Improvement Study to see their ideas for a tunnel that would link I-295 and the SE/SW Freeway for through traffic, leaving South Capitol Street to become the grand urban gateway boulevard planners envision. At Wednesday's public meeting on the South Capitol Street Draft Environmental Impact Statement, DDOT said that the tunnel isn't totally off the table, but they decided that a new Douglass Bridge and other South Capitol Street improvements could move forward separately. But could a tunnel still work if the dream of dismantling the SE/SW Freeway were realized?

* I've tried to remain (mostly) unopinionated on various projects during the five years I've run this site. But sometimes, it's necessary to take a stand, to come out from behind the cloak of neutrality and crusade for what you believe in. So I'm going to take advantage of this bully pulpit and fight for one thing: Arched Bascule!
