D.C. officials are hoping to have the intersection of 14th and F streets NW open Friday evening for the first time since a sinkhole developed 10 days ago. Some other road work will be underway, including the opening of two new ramps at the District’s 11th Street Bridge. Metrorail will be working on all five lines.

Metro weekend delays

These disruptions will affect service from 10 p.m. Friday through the rail system’s midnight closing Sunday.

Red Line. Free shuttle buses replace trains between Woodley Park and Metro Center. The Dupont Circle and Farragut North stations will be closed. Between Shady Grove and Woodley Park, trains are scheduled to operate every 10 minutes during the daytime and every 15 to 20 minutes at other times. Between Metro Center and Glenmont, they will operate every 15 minutes during the day and every 15 to 20 minutes at other times.

The shuttles will operate on two routes. Express buses will make no stops between Woodley Park and Metro Center. If you take one, add 20 minutes to your normal travel time between these points. The local service will make all stops. Taking the local all the way would add about 25 minutes to normal travel time, Metro said.

On the other lines, trains are scheduled to operate every 22 minutes throughout the weekend as trains share tracks through five work zones. Metro said the schedule is set up so that the extra wait time should be spent on the platforms. Once the train leaves the platform, there should be no further delay.

If your actual experience reflects this plan, it’s an improvement. It means you don’t waste time on trains that stop and start as they wait their turn to go through the single-track zones.

Riders who look at Metro’s online Trip Planner after midday Friday should find that the weekend schedule reflects the timing adjustments made to accommodate the work zones. This should take a lot of the guesswork out of a weekend Metrorail ride and reduce wait times on platforms for those who consult the Trip Planner.

These are the work zones.

Blue Line. Trains will share a track between Stadium-Armory and Addison Road.

Blue, Yellow lines. Trains will share a track between Braddock Road and Van Dorn Street.

Orange Line. Trains will share a track between Stadium-Armory and Cheverly.

Green Line. Trains will share a track between Anacostia and Southern Avenue and between Greenbelt and College Park.

Anacostia Riverwalk Trail

The pedestrian and bicycle bridge over the railroad tracks north of the Sousa Bridge is done. That opens up a link along the Anacostia Riverwalk Trail between South Capitol Street and Benning Road east of the Anacostia River.

So far, 12 miles of what will eventually be 20 miles of Riverwalk are open. The goal is to provide a seamless pedestrian and bicycle trail between the Tidal Basin and Bladensburg Marina Park in Maryland.

11th Street Bridge ramps

The District Department of Transportation is opening two new ramps on the 11th Street Bridge’s local span, the southernmost of the three. One ramp provides access to northbound D.C. 295, the Anacostia Freeway. The other takes drivers from southbound D.C. 295 onto the local span. This will be helpful to travelers heading for Anacostia, Capitol Hill, the Navy Yard and Nationals Park.

Note that they connect with an intersection on the local span that is controlled by a traffic signal. To reach the ramp from southbound D.C. 295, head down the previously opened ramp, the one that takes traffic onto the inbound freeway span, but stay to the left and take the new exit that veer off to the left and leads to the local span.

K Street festival

At 1:30 p.m. Saturday, D.C. Mayor Vincent C. Gray is scheduled to cut the ribbon at Fifth and K streets NW marking completion of the K Street Streetscape project. This is part of a music, food and arts and crafts festival from noon to 4 p.m.

The project, launched in spring 2012, upgraded K Street between Third and Seventh streets NW in the area known as Mount Vernon Triangle.

Taste of Georgetown on Saturday

The Taste of Georgetown food festival at Wisconsin Avenue and M Street NW is scheduled for 11 a.m. to 4 p.m. Saturday. Wisconsin Avenue between M and K streets is scheduled to close from midnight to 9 p.m. Saturday.

Arlington parade Saturday

The Corso de Santa Cruz Parade in Arlington County is scheduled for noon to 3 pm. Saturday. These streets will be closed during the parade:

  • The right southbound lane of South Shirlington Road between South 25th Street and South Four Mile Run Drive from 7 a.m. to 4 p.m.
  • Both westbound lanes of South Four Mile Run Drive between South Shirlington Road and South Walter Reed Drive from 10 a.m. to 4 p.m. (Westbound traffic can use South Arlington Mill Drive.)
  • The right northbound lane of South Walter Reed Drive between South Four Mile Run Drive and South Randolph Street from 10 a.m. to 4 p.m.

Manassas Railway Festival

The 19th annual railway festival will be celebrated from 10 a.m. to 4 p.m. Saturday in Old Town Manassas. The event draws tens of thousands to the middle of the city for the historic displays, the train rides, the blue grass music and the food.  The Old Town Train Depot is at 9431 West St.

Maine Avenue

The National Park Service plans to close westbound Maine Avenue SW under the 14th Street Bridge from 9 p.m. Friday to 6 a.m. Sunday to repair the concrete road base.

Westbound drivers heading for points beyond the 14th Street Bridge will be rerouted east along 12th Street SW to Independence Avenue SW. Travelers headed westbound on I-395 to Maine Avenue SW will be rerouted north on Sixth Street SW to Independence Avenue SW.

New York Avenue Bridge

Only single lanes will be open on both sides of New York Avenue NE between Florida Avenue and Penn Street from 10 p.m. Friday to 11 a.m. Saturday for work that’s part of the long-term reconstruction of the New York Avenue Bridge over the railroad tracks north of Union Station.

Post Hunt on Sunday

The annual Post Hunt is at Freedom Plaza, starting at noon Sunday. Pennsylvania Avenue NW between 13th and 14th streets will be closed from 7 a.m. to 6:30 p.m. Because of the street closing, Metrobus Routes 32 and 36 will be detoured. From 7 a.m. to 7 p.m., they won’t stop at 12th, 13th and 14th streets along Pennsylvania Avenue NW.

This coming week …

Meeting on Virginia parkway plan

Monday night, the Virginia Department of Transportation plans to explain why the state wants to build a 10-mile, north-south highway that would link Interstate 66 in Prince William with Route 50 in Loudoun. This is sure to be a lively session, drawing many residents of Prince William and Loudoun counties who oppose the project. It also will include discussion of the proposed highway between Route 50 and Route 606 on the west side of Dulles International Airport.

The meeting is scheduled for 7 p.m. Monday at the Hylton Performing Arts Center, 10960 George Mason Circle, Manassas. VDOT plans to make a presentation in the auditorium at 7 p.m., followed by a question-and-answer session from 7:30 to 9 p.m.
