Travelers should expect more clouds, more showers, and more mugginess for the first part of the week, the Capital Weather Gang says, but there’s more sun and less heat in the forecast for the weekend..

Many changes in Metrobus routes occurred over the weekend. See the list below. Metrorail doesn’t have any major track work planned for this weekend, but should release a schedule later this morning showing the work zones that will require trains to share tracks, creating delays.

On the roads, there are plenty of changes in the D.C. region’s big projects that will set up different traffic patterns.

Metrobus changes

These changes in routes and schedules took effect on Sunday.

The District

— Route 70 (Georgia Avenue-7th Street Line) now operates between Silver Spring and Archives Metrorail stations. During weekday peak periods, buses will operate every 10 minutes, rather than every 12 minutes, as under the old schedule. Route 71 has been discontinued.

— Route 74, a new route between the Washington Convention Center and the Southwest Waterfront, replaces the southern portion of Routes 70 and 71. It will operate daily between 5 a.m. and 1 a.m., with service every 18 minutes during weekday peak periods and every 24 minutes at other times. On Friday, the District plans to eliminate the Circulator bus that operates on a similar route about every 10 minutes.

— Routes 90, 92 and 93 (U Street-Garfield Line) use a new type of schedule. On weekdays between 6 a.m. and 7 p.m., Route 90 will operate every 15 minutes between Anacostia Station and Duke Ellington Bridge Route 92 will operate every 15 minutes between Congress Heights station and 14th and U streets NW.

At stops served by both routes, buses should arrive about every seven or eight minutes. Metro says that supervisors will be on the streets to manage the operations and minimize the bunching up of the buses in heavy traffic.

— Two new afternoon weekday westbound trips operate on Route 32 (Pennsylvania Avenue Line), leaving Southern Avenue Metro station at 4:16 and 4:46 p.m. The buses will travel to Eastern Market.

— On Route H6 (Brookland-Fort Lincoln Line), several early morning trips have been adjusted to improve connections to Red Line trains at Brookland.

— All service on Route K1 (Takoma-Walter Reed Line) has been discontinued, now that the federal base realignment program has relocated staff and patients from Walter Reed Army Medical Center to Bethesda.

— Route N8 (Tenleytown-Glover Park Line) has been discontinued, because the ridership is too low, Metro said.

— Route N2 (Massachusetts Avenue Line) has been rerouted between Friendship Heights station and Ward Circle as a partial replacement for Route N8.

— On Routes N3 and N4 (Massachusetts Avenue Line), several morning departures from the Friendship Heights station have been adjusted to reduce congestion at the bus terminal.


These are the Metrobus changes affecting riders in Northern Virginia.

— Route 3Y (Lee Highway-Farragut Square) has been extended westward from Lee Highway and Woodrow/Albemarle streets to Lee Highway and George Mason Drive/Harrison Street. This will give more riders a direct trip to Farragut Square. Metro also will add two trips on weekday mornings and evenings.

— Route 7A (Lincolnia-North Fairlington Line) via Landmark Center has been discontinued after 11 p.m. on weekends. Adjustments have been made to the schedule on several late-night trips leaving Lincolnia Road/Quantrell Avenue.

Special bus fare discontinued

Metro has discontinued the special Anacostia fare. Fares have changed from $1 to $1.50 for riders using SmarTrip and $1.70 for those paying cash.

This affects Routes 94, A2, A4, A5, A6, A7, A8, M8, M9, W2, W3, W6, W8 as well as stops from Good Hope Road south on Routes 90, B2, P1, P2, P6 and U2. Riders transferring between bus and rail will not notice a fare change, because the SmarTrip discount for riders transferring at Anacostia or Congress Heights stations will increase from 50¢ to $1.

Beltway/Telegraph Road

Here’s the schedule of off-peak and overnight lane closings for the reconstruction of the Capital Beltway’s Telegraph Road interchange.

Monday and Tuesday, 9 a.m. to 3 p.m.: The left lane of the inner loop will close between Telegraph Road and the Eisenhower Connector for roadway construction.

Monday through Thursday, 8 a.m. to 4 p.m., and Saturday, 7 a.m. to 3 p.m.: The ramp from Telegraph Road South to the outer loop will be closed. Drivers should take the ramp to Huntington Avenue East to Route 1 North to the outer loop.

Monday through Thursday, 8 a.m. to 4 p.m., and Saturday, 7 a.m. to 3 p.m.: The ramp from Telegraph Road North to the outer loop will be closed. Drivers should take Huntington Avenue East and make a left on Route 1 North to the ramp to the outer loop.

Monday night, 9 p.m. to 5 a.m.: The outer loop THRU lane will be closed at Telegraph Road. Starting at 11 p.m., one LOCAL lane also will close. One LOCAL lane will remain open.

Wednesday night, 9 p.m. to 5 a.m.: The right lane of the outer loop will close between Eisenhower Avenue and Telegraph Road. There will be a complete closure of the outer loop for about 15 minutes just after midnight.

Rock Creek Parkway

Resurfacing operations are scheduled to begin today in the southbound lanes between Beach Drive and Waterside Drive. The work will continue through Friday. Expect lane closings.

Beginning Wednesday, resurfacing work will be underway in the southbound lanes between Beach Drive and Waterside Drive. This will continue through Friday, with lane closings.

Constitution Avenue

Monday through Friday, from 5:30 a.m. to 7 p.m., expect to find up to three westbound lanes closed on Constitution Avenue NW between 23rd and 17th streets for milling, base repair, sidewalk installation and streetlight work. A minimum of two lanes will be open in each direction during rush hours.

Eastbound Constitution Avenue will be open to traffic between 23rd and 15th streets, but temporary lane closures will occur for various jobs, such as work on light poles and signs.

Dulles Metrorail project

The left lane of both westbound and eastbound Interstate 66 will continue to be closed Mondays through Thursdays, 9:30 a.m. to 3:30 p.m., and Fridays, 9:30 a.m. to noon, from the Dulles Connector Road (Route267) split to the Great Falls Street overpass. In addition, the eastbound left lane will be closed from 9:30 p.m. to 5 a.m. weeknights, and 9:30 p.m. to 9 a.m. overnight Friday.

These lanes are closed to create a safe work zone for construction of a retaining wall and for other concrete work at that flyover for the new rail line.

Construction of the Tysons West Metrorail station continues in the median of Leesburg Pike (Route 7) between Spring Hill Road and Tyco Road/Westwood Center Drive. Overnights this week, crews will be working on the bridge near the station. Workers also are installing a water main there. Motorists will be directed to detour via other cross streets along Route 7.

Beltway HOT lanes

Twelve interchanges along 14 miles of the Capital Beltway between the Springfield interchange and the Dulles Toll Road (Route 267) for the high occupancy toll lanes. In some sections, the new general purpose lanes on the outer edges of the Beltway have opened, so that work could begin on the new lanes in the middle, which will become the HOT lanes.

The project is scheduled to be done in December 2012. I plan to give you a progress report on this Sunday’s Commuter page in the Post’s Metro section.

This week, watch for more single lane closings during off-peak daytime and overnight hours on the Beltway and at the interchanges.

Beltway exit to close

Variable message boards along the Capital Beltway in Virginia are warning drivers about a major change in the traffic pattern coming up around the end of the week along the inner loop.

The left lane exit (49C) to westbound Interstate 66 in Virginia is scheduled to close permanently as construction continues on the high-occupancy toll lanes project.

Watch for some additional traffic congestion at the I-66 interchange immediately after the closing. All inner loop drivers heading to westbound I-66 will then use the right-side ramp, exit 49A, which is being widened to accommodate the extra traffic.

Pennsylvania Avenue SE

Starting today, the District Department of Transportation plans to temporarily restrict lanes on Pennsylvania Avenue SE between Branch and Southern avenues to complete roadwork on the Pennsylvania Avenue Great Streets project. During this phase, a single lane will be open in each direction on Pennsylvania Avenue.

Traffic between Branch Avenue and 38th Street will be reduced to one lane in each direction through October. The portion of the project from 38th Street to Southern Avenue will be reduced to one lane in each direction from October through December.

Once the segments are rebuilt, the new lanes will be opened to allow for two lanes of traffic in each direction.

Work will take place between 7 a.m. and 7 p.m. Mondays through Saturdays. Work zones will be expanded as needed, DDOT said. Sidewalks will be kept open, and temporary crosswalks will be set up at intersections.

Traffic delays are likely. DDOT suggested that drivers use alternative routes, which include Suitland Road to Alabama Avenue to Good Hope Road, and Massachusetts Avenue to Minnesota Avenue.
