Tysons, VA

Much of the roads affected by the flash floods two weeks ago have been fixed, but two routes through McLean remain out of commission and will require long term repairs.

Kirby Road and Swinks Mill Road at the eastern and western edges of McLean respectively are both blocked off at roughly the halfway point where the roads were severely damaged by floodwaters.

Replacing the damaged bridges will take several months, according to Virginia Department of Transportation (VDOT) spokesperson Ellen Kamilakis.

A part of Kirby Road has been broken off with much of the supporting infrastructure underneath completely swept away. According to a press release from VDOT:

  • A segment of road just south of Claiborne Drive was washed away. The remaining asphalt in that location has been undermined.

  • Asphalt on the approaches to the deck of the VDOT bridge over Pimmit Run was damaged, but temporarily repaired the same day. The bridge also has damage to the guardrails and abutments (the “legs” that support the bridge deck) and retaining wall.

  • Pimmit Run will need to be realigned to its original location.

  • The sanitary sewer line and underground utilities were affected.

  • Damage to VDOT infrastructure is not preventing access to any homes.

  • Note: A privately owned and maintained bridge across from Claiborne Drive was severely damaged and homeowners are evaluating repair options.

Meanwhile, at Swinks Mill Road the asphalt on the bridge was completely destroyed, with the guard rail and large chunks of the road visible warped and scattered down the creek bed. According to the VDOT press release:

  • Several hundred feet of asphalt approaching the bridge on both sides was damaged.

  • Asphalt on the bridge deck was destroyed. Also, the bridge has sustained damage to the guardrails, abutments, and retaining wall.

  • Bridge scour (removal of sand and gravel from around the abutments) was observed.

  • Debris was observed in Scotts Run.

  • Damage to VDOT infrastructure is not preventing access to any homes.

Currently, VDOT said surveys are underway for the planned realignment of both streets. Preliminary design work has started for both bridges and road repairs, according to the press release.

Removal of debris is expected to continue alongside more extensive survey work at both locations. Once bridge designs are finalized, VDOT said the bridge and road repair plans will be put out for construction bids.
