Construction crews will soon demolish the Gallows Road bridge over I-66, a process that is expected take 30 to 40 nights, starting on or about next Wednesday (Oct. 13).
The work will involve breaking up the concrete deck with jack hammers, saw cutters and heavy equipment consisting of hoe rams. It’s part of the Transform 66 Outside the Beltway project, which is adding express lanes on the interstate from I-495 in Dunn Loring to Gainesville.
“These are not necessarily 30 to 40 consecutive nights of demolition, and…some demolition activities are less disruptive than others,” said Nancy Smith, a spokesperson for FAM Construction, the design-builder of the project.
The company said at a public information meeting on Monday (Oct. 4) that the demolition will occur after traffic shifts.
Segments over I-66 will be affected overnight — typically 11 p.m. to 5 a.m. — when multiple lanes of the interstate can be closed, Smith said. For work not over I-66, demolition will take place during the daytime.
Information on lane closures and other travel changes will be posted on the project website, which also has provides information via email notifications and traffic alerts.
The demolition timeline extends into the late fall due to weather and other factors, but no demolition work will occur over the Thanksgiving holiday weekend.
Project officials previously expected the demolition work to start in mid-August. VDOT told Tysons Reporter that the slippage in the schedule is not expected to impact the overall project schedule.
The new I-66 express lanes are still slated to open in December 2022.
The Gallows Road bridge is just feet above the Dunn Loring-Merrifield Metro station, requiring coordinating with the Washington Metropolitan Area Transit Authority.
To minimize impacts, crews will haul concrete away to be processed off site, position work area lighting to face toward the roadway and away from residences, implement “dust control measures,” and monitor construction vibrations and noise, Smith said.
At Monday’s information meeting, however, neighbors compared previous construction to an earthquake and reported that vehicles have been running red lights amid “frustration and confusion” as traffic goes over the bridge.
VDOT megaprojects director Susan Shaw said she would coordinate with their team to notify county police about the safety concerns.
Among the traffic adjustments, FAM Construction reported that:
- Northbound bridge traffic will shift to the new bridge starting next week or around that time
- Southbound bridge traffic will shift into a temporary alignment onto the new bridge on or about the week of Oct. 18
- Pedestrian access will remain on the west side of the old bridge until southbound travel lanes shift on or about the week of Oct. 18. Once those southbound lanes shift to the new bridge, pedestrian routes will be on the east side of the bridge
- The shift in travel lanes on Gallows Road does not affect the entrance at Stenwood Elementary School as the changes are south of the school entrance
Updates will be posted to outside.transform66.org/gallowsroad as demolition progresses.
