Road crews will be very active across the D.C. region this week, and the annual tennis tournament in the District also is likely to create congestion. The 14th Street Bridge project is scheduled to wrap up work this weekend on the northbound span. Metrorail’s maintenance schedule includes a major shutdown for the weekend.

This amazing string of 90-degree-plus days could continue through the work week, the Capital Weather Gang says. A few thunderstorms may develop later today, but the week ahead looks mostly dry.

Here’s what to watch for on the roads and rails.

D.C. ticket amnesty

The District’s plan to suspend penalties on old parking, photo enforcement and moving violation tickets takes effect today. Drivers can pay older tickets online at or in person at 301 C St. NW. The program is scheduled to end Jan. 27.

D.C. officials estimate that the city will collect $6.3 million through the ticket amnesty.

Tennis on 16th Street

The annual Legg Mason Tennis Classic continues through Sunday at the FitzGerald Tennis Center, 16th and Kennedy streets NW.

Tennis fans can take the Red Line to the Van Ness station and board a free shuttle to the stadium. (However, its very important to note the Metrorail disruption scheduled for this weekend. See below.)

The shuttle service, operating every 10 to 12 minutes, will begin 90 minutes before the start of matches through Friday. For the final weekend, the shuttles will begin two hours before the start of the matches. The service continues for a half-hour after the end of the last matches each day.

Another transit option: Take the S2 or S4 Metrobuses that operate between Silver Spring and downtown D.C. via 16th Street NW.

Major Metrorail project this weekend

Medical Center, Grosvenor and White Flint stations on the west side of the Red Line are scheduled to be closed Saturday and Sunday while Metro does maintenance work along the route. Free shuttle buses will replace the trains between Bethesda and Rockville.

That’s the most significant rail disruption to know about for those heading to the final weekend of the tennis tournament. But one other disruption will occur on Sunday only: Franconia-Springfield and Van Dorn Street stations will be closed, affecting rail service on the Blue and Yellow lines. Free shuttle buses will replace trains between Franconia-Springfield, Van Dorn Street and Eisenhower Avenue. Blue Line trains will originate and terminate at Huntington, rather than Franconia-Springfield.

Constitution Avenue NW

Monday through Friday between 5:30 a.m. and 3:30 p.m., drivers may find up to two lanes of Constitution Avenue in each direction closed between 23rd and 17th streets NW for a reconstruction project, the National Park Service said.

At night, between 7 p.m. and 5:30 a.m, up to three lanes may be closed in each direction between 18th and 16th streets.

Two eastbound lanes nearest the curb on Constitution Avenue between 21st and 19th streets will be closed all day until Wednesday. Beginning Thursday morning, those two lanes will be closed all day between 19th and 17th streets. They are scheduled to reopen by the middle of the following week.

This Saturday, between 7 a.m. and 5 p.m., expect up to three lanes on either side of Constitution Avenue to be closed between 23rd and 17th streets NW.

Maryland repaving projects

These are the locations and times for some lane closings announced by the Maryland State Highway Administration.

— Rockville Pike between First Street and Templeton Place, 9 p.m. to 5 a.m. through Thursday night.

— University Boulevard between Arcola Avenue and Colesville Road, 9 a.m. to 3 p.m. Monday through Friday.

— Georgia Avenue between New Hampshire Avenue and Queen Elizabeth Drive, 8 p.m. to 5 a.m. through Thursday night.

— Georgia Avenue between Norbeck Road and Glenallan Avenue, 9 a.m. to 3 p.m. and 7 p.m. to 9 p.m., Monday through Friday.

I-95 widening done

The Virginia Department of Transportation has opened the widened portion of Interstate 95 ahead of schedule. The project to add a fourth lane between the Fairfax County Parkway and Route 123 began in 2008 and was scheduled to be completed in early fall. Crews still are working on some finishing touches along the highway, but that won’t affect traffic, said Mike Salmon, a VDOT spokesman. In addition to the widening, the project also extended the acceleration lane from Route 123 to southbound I-95.

Beltway/Kenilworth Avenue

Watch for lane closures on the Capital Beltway in Greenbelt, where the Maryland State Highway Administration is rehabilitating the Kenilworth Avenue bridge. The closings are scheduled for 9 a.m. to 3 p.m. Monday through Friday, and 9 p.m. to 5 a.m. Sunday through Thursday nights. After midnight, drivers may find as many as three lanes closed.

Beltway/Forestville Road

Single lane closings are scheduled for the Capital Beltway at Forestville Road, where the Maryland State Highway Administration is rehabilitating the bridge. The lane closings can occur from 9 a.m. to 3 p.m. Monday through Friday and from 9 p.m. to 5 a.m. Sunday through Thursday.

New Fairfax Parkway ramp

Drivers going from Springfield to Boudinot Drive in Newington now have a direct route, with the opening of the ramp from the southbound lanes of the Fairfax County Parkway to Boudinot. From Boudinot, motorists can reach Fullerton Road, Alban Road and southbound I-95.

Part of the ramp opened in June, but this ramp’s opening was delayed because of a problem with the retaining wall, the Virginia Department of Transportation said.

Anacostia Freeway

The District Department of Transportation is repairing the bridge over the Anacostia Park entrance on the Anacostia Freeway (DC-295). Work is scheduled to continue through Sept. 20. The work hours are 7 a.m. to 4 p.m. and 8 p.m. to 5 a.m. Single lanes will be closed.

Hunter Mill Road bridge

This coming week, the Hunter Mill Road bridge over Difficult Run in Fairfax County will be narrowed to one lane during off-peak hours, the Virginia Department of Transportation said.

An annual inspection of the bridge, between Hunter Station Road and Lawyers Road, showed severe corrosion of the steel beams, VDOT said. As a first step toward repairing it, surveyors, drill rigs, engineers and maintenance workers make test borings and collect other information needed to begin construction.

Workers will replace the bridge with a temporary truss, and the weight restriction is being lowered as a safety measure, VDOT said. For one or two weekends in August, VDOT will close the bridge and detour traffic. Those dates haven’t been announced yet. Construction of the permanent replacement is targeted for summer 2012.

Beltway/Telegraph Road

The Wilson Bridge project plans to close westbound Pershing Avenue in the Eisenhower Valley of Alexandria starting Friday and continuing for two months. Drivers will not be able to take Pershing Avenue to Telegraph Road North toward Duke Street.

The closing will clear space for workers to build the new Pershing Avenue approach to the widened Telegraph Road bridge over the railroad tracks.

Detours: Drivers can take Stovall Street North, then make a right on Mill Road and a left on Eisenhower Avenue to the traffic circle to Holland Lane and Duke Street. They also could take Stovall Street South, make a left on Eisenhower Avenue to the traffic circle to Holland Lane and Duke Street. There will be detour signs posted.

Project managers said the work is highly dependent on favorable weather, and may be delayed or prolonged by rain. (The forecast for the week includes very little prospect for rain.)

14th Street Bridge project

The lane closings on the northbound span of the 14th Street bridge are about to end after two years of rehabilitation work. The District Department of Transportation says that the final resurfacing work is scheduled for this weekend. After the permanent pavement markings are put down, all lanes will be open in their original configuration.

During the project, drivers have had to adjust to periodic shifts in the lane configuration. The plan kept all four lanes open during rush periods, but caused some confusion among drivers as they adapted to the changes and tried to figure out when they needed to change lanes to reach either 14th Street NW or the Southeast-Southwest Freeway.
