Immediately after the new bridge opens, crews will demolish the 63-year-old existing bridge during overnight hours. Demolition involves hammering, saw cutting and crushing the concrete deck, and lifting/removing chunks of concrete and steel beams with cranes. For safety reasons, this work must occur during overnight hours, as it requires multiple lanes on I-495 (Capital Beltway) to be closed.
Additionally, demolition work will require reducing Old Dominion Drive to a single lane, with flaggers directing traffic in alternating directions. Demolition of the old bridge is anticipated to be completed by late February to early March.
