The incident happened around 5:00 a.m. Police say a 21-year-old man from Leesburg was driving a white 2008 BMW M5 at approximately 90 miles per hour over the Key Bridge when the car hit the curb of a traffic island on the Rosslyn side of the bridge, flipped 5 times and ended up in the bushes of the Key Bridge Marriott. The force of the accident sheared the sports car’s roof off, according to Arlington County Police spokesman Dustin Sternbeck.

There were two passengers, ages 21 and 22 and both from Leesburg, in the vehicle at the time of the accident.

The driver was pronounced dead at the scene, one passenger was ejected and found unconscious a short distance from the vehicle, and the other was pulled from the wreck by VDOT workers who witnessed the accident, Sternbeck said. Both passengers were transported to a local hospital with what were described as critical injuries. They remain in serious condition. One passenger is in a medically-induced coma with three broken vertebrae, a broken left scapula, pulmonary contusions, and hemotoma around the heart, according to police.

The driver has been identified by police as 21-year-old Sami Ullah of Leesburg. Yesterday, less than 24 hours before the accident, Ullah posted a photo of his car on Instagram with the caption “I call her Snow White. #m5 #beast #snowWhite #conlosterroristas #570 #ponies #vroomVroom.”

Update at 7:35 p.m. — The man has been safely taken into police custody. The scene is now being cleared.

Update at 6:10 p.m. — Police are still attempting to talk and negotiate with the man. A SWAT team is now reportedly on scene.

Police are blocking either side of the Key Bridge due to a person threatening to jump.

A man is hanging on to the southeast side of the bridge and threatening to jump, according to scanner traffic and witnesses. We’re told that a helicopter and a Coast Guard boat are assisting police, who are trying to talk with the man.

D.C. and Arlington police have shut down vehicle and pedestrian traffic to the bridge. Inbound traffic from Arlington is being diverted onto Lee Highway and the George Washington Parkway.

Significant traffic backups have been reported in Rosslyn, particularly at the intersection of Lynn Street and Wilson Blvd. Earlier, police looked into reports of motorists getting out of their cars and yelling obscenities at each other as a result of the backups.

Starting this week, the police department has assigned extra traffic patrols to the area during the morning rush hour, when gridlock gets especially bad on Lynn Street. (Although traffic is often heavy during the evening rush hour, as well.)

The officers will remind drivers that it’s illegal to block the box — to enter into an intersection during a green light when there is no room to clear the intersection. For now, the officers will not be issuing citations, according to ACPD spokesman Dustin Sternbeck, who called morning congestion on Lynn Street a “disaster.”

“You should expect to see additional police presence in that area,” Sternbeck said. ”We’re hoping in the immediate future that this education campaign will get people to change their behavior. Hopefully we can make an impact there, because it’s been a concern for a long time.”

In support of the campaign, the Transportation Engineering and Operations Bureau of Arlington’s Department of Environmental Services will be installing “Do Not Block Intersection” signs at all of the intersections along N. Lynn Street between Wilson Boulevard and the Key Bridge. Existing Do Not Block Intersection signs at N. Lynn Street and Wilson Boulevard, meanwhile, will be replaced with larger versions of the sign.

“The signs are currently being fabricated and should be installed within the next three (3) weeks,” said DES spokeswoman Myllisa Kennedy. In addition to the signs, this coming spring DES will be installing pavement markings at the Wilson Boulevard and Lynn Street intersection which are intended to “help define the ‘box.’”

Lynn Street serves commuters heading to the GW Parkway, I-66 and D.C. via the Key Bridge.

The picture on the left is the area formerly known as Rosslyn Circle, taken around 1925. Records indicate the businesses shown were on Agnew Avenue, which is now Lynn Street. They stood at the base of the newly finished Key Bridge, which replaced the Aqueduct Bridge in 1923.

Rosslyn, and this section in particular, used to be considered a rough area. After the Civil War ended, many soldiers stayed behind. They drove out the farmers who previously owned the land in Rosslyn, and set up saloons, gambling houses and houses of prostitution. Thievery and murder were a regular occurrence, and locals knew not to walk there at night, if at all.

By the early 1900s, fed up residents wanted to rejuvenate the area and formed groups such as the “Anti-Saloon League.” They worked to change Rosslyn’s colloquial slogan from “Gateway to Perdition” to “Gateway to Virginia.” It took decades to drive out the unsavory elements.

By the 1950s, big plans were in the works to fully transform Rosslyn Circle and the surrounding area from a slummy, dangerous part of town teeming with pawnbrokers into a business hub sporting high rises. Much of the area was razed, both to accommodate the new buildings, and to make way for the completion of Interstate 66.

By about 1963, nearly all of old Rosslyn was gone, and businesses and industry poured into the area. Adding to the renewal was the promise of a Metro station, which was completed in 1977.

The publicity stunt will start at the intersection of N. Lynn Street and Lee Highway in Rosslyn. “Flight Time” will dribble and spin basketballs for one mile from the intersection, across the Key Bridge, and to a basketball court at a playground in Georgetown. (See a map of the route here.)

“Flight Time’s grand arrival tips off ‘Globetrotter Week’ in the D.C. metropolitan area, which includes multiple school visits and goodwill appearances,” the Globetrotters said in a press release. “The week concludes as the Globetrotters bring their one-of-a-kind skills to town for three big games on March 24 & 25: Verizon Center in Washington D.C. (Sat., March 24 at 1 p.m.) and the Patriot Center in Fairfax, VA (Sat., March 24 at 7:30 p.m. and Sun., March 25 at 2 p.m.).”

The northbound (inbound) lanes of the Key Bridge are closed due to a “police situation.”

Initial reports suggest a person may have jumped off the bridge, possibly on the D.C. side. Traffic cameras show Arlington police redirecting traffic heading toward the bridge on N. Lynn Street onto northbound Lee Highway and the George Washington Parkway.

Traffic appears to be flowing from the District into Arlington across the Key Bridge.

Very heavy traffic has been reported in Rosslyn and across the bridge in Georgetown.

Update at 5:55 p.m. — The few protesters who made it to the Virginia side of the Key Bridge were “pretty low-key,” says Arlington County police spokeswoman Det. Crystal Nosal. No arrests were made and no injuries were reported. A small group of young protesters wearing anarchist symbols and bandanas over their faces had a brief but peaceful confrontation with Arlington police that ended with the group crossing back into D.C.

Update at 4:50 p.m. — After a peaceful occupation of one of the bridge’s sidewalks, protesters have largely dispersed. Traffic on the Key Bridge is currently light and unobstructed.

Earlier: Several dozen Arlington County police officers in riot gear are stationed on the Virginia side of the Key Bridge, waiting to see if protesters from the Occupy D.C. movement decide to cross.

The heavy police presence on the Rosslyn side of the Potomac is accompanied by the presence of D.C. police mid-span and on the Georgetown side, and a U.S. Park Police helicopter overhead.

A couple hundred protesters are said to be marching in the District, compared to just over a dozen ‘Occupy NoVA’ demonstrators — mostly Verizon CWA union members — who marched down Wilson Boulevard around 3:00 this afternoon.

The District Department of Transportation (DDOT) and the Metropolitan Police Department (MPD) are advising the public about the possibility of traffic delays during the evening rush hour today (17 Nov) due to a planned demonstration and march by Occupy DC in the vicinity of the Key Bridge and McPherson Square.

The demonstration / march is scheduled to begin at 1430 and continue through the evening rush hour. Potential impacts include the possibility of heavy pedestrian and motor vehicle traffic between the Key Bridge, McPherson Square, and surrounding areas.

Arlington and D.C. police are stationed on either side of the Key Bridge to ensure the march remains orderly.

The march is timed to coincide with a march by Occupy D.C. from McPherson Square to the Key Bridge — which some fear may snarl afternoon rush hour traffic.

“A national day of action is taking place around the country in the Occupy movement,” Occupy NoVA said on its website. “We are going to be marching on this day in solidarity with Occupy DC, from Welburn Square to join in a Labor-Community-Occupy Day of Action and March on the Key Bridge in Rosslyn/Georgetown in protest of the deterioration of our public infrastructure and public services.”

Protesters are expected to gather in Welburn Square at 2:00 p.m., before starting their march around 3:30 p.m. The marching route — which would take demonstrators through the heart of Clarendon, Courthouse and Rosslyn — includes parts of Wilson Boulevard, Clarendon Boulevard and N. Lynn Street. It’s not clear if protesters will be marching on the sidewalk or in the street.

So far, Arlington County Police have not had any comment on their planned response to the protest. Last week an Occupy D.C. spokesman told ARLnow.com that the movement was aware of the Occupy NoVA group’s existence.

Occupy NoVA has not yet set up any encampments, but the group says on its website that it will discuss further plans at meetings on Thursday.

Two of three northbound lanes are closed on the Key Bridge due to a presidential speech in Georgetown.

The lane closures are causing traffic to back up in Rosslyn, before the bridge.

President Obama is currently speaking in Goergetown Waterfront Park, near the Key Bridge. The speech started around 11:30 a.m.
