Drivers will be detoured to the long trek down I Street/Virginia Avenue to the ramp at 3rd Street, SE, as the latest arrow-filed map from DDOT shows. (So be careful at the 3rd and Virginia intersection, which might get a bit hairy.)

"The opening of the new ramp provides a direct connection from Capitol Hill and the Navy Yard/Barracks Row area to northbound DC 295 and southbound I-295 via 8th Street SE."

This ramp, while technically new, is really just the replacement of the old ramp at 8th and Virginia, albeit now shifted a few yards to the north on 8th. My photo above, from a few weeks ago, shows the new ramp, with the outbound freeway lanes to the left, and at right, the under-construction ramp that will bring traffic from the freeway down to the new signalized interchange at 11th Street.

DDOT has also provided a spiffy map for the new ramp, showing all sorts of arrows.

Plus, as in past years, the buses will have extended hours for Nats games: For every game beginning at 4:05 pm or later, the buses will run until midnight. For Sunday home games, this route will run from 10 am to 10 pm.

This route also stops at the Eastern Market station on the Orange and Blue lines, and also runs along Barracks Row, so your $1 gives you a lot of options.

"As part of the 11th Street Bridge Project, the District Department of Transportation (DDOT) will close 11th Street SE, between M Street and K Street, from 7 a.m. on Saturday, March 22, to 11 p.m. on Sunday, March 23, 2014. This closure will also take effect the following weekend, from 7 a.m. on Saturday, March 29, to 11 p.m. on Sunday, March 30, 2014. The 11th Street SE access ramp to westbound I-695 (Southeast/Southwest Freeway) will also be closed during these two closures. The work will allow crews to begin demolition of the existing inbound bridge structure over 11th Street. " See the map for details.

This shift will also provide a third lane of inbound traffic, and clear the way for demolition of the old, now-somewhat-rickety-feeling, inbound flyover. (Yay!)

In order to complete the final prep for this switchover, the exit ramp from I-695 to M Street will be closed on Thursday, March 6, at 10 pm, until approximately 5 am Friday. If you need to get to M Street from 295, you can get off at the 11th Street local exits and proceed to M that way.

This alignment switch is the second in a series of traffic changes related to the 11th Street Bridges project on tap for the early part of 2014. Next in line should be the revamped ramp from 8th Street SE onto the eastbound freeway, sometime this spring, followed in the summer by the new ramp from the eastbound freeway down to 11th Street north of L.

However, as is so often the case, progess comes with a price: "Motorists seeking access to 8th Street SE and the Marine Barracks area from the inbound 11th Street Freeway Bridge (westbound I-695) will be detoured to M Street SE, then to 11th Street SE to I Street SE." See the map above for this detour route.

On the graphic released a few weeks ago about the 2014 openings (above right), there appears to eventually be a return of access from westbound I-695 to I Street SE, but is not part of the announced schedule. (It also appears to use the closed-for-security-reasons ramp that bisects the Marine Barracks on I Street, and I'm wondering about the machinations to reopen that.) There will eventually be other movements to and from 11th Street as part of the still-under-discussion Southeast Blvd.
