Repairs to the Edmonston Drive Bridge are scheduled to begin in July and bring major traffic impacts to Rockville’s only bridge over the Metrorail and CSX tracks.

Construction will begin the week of July 16 on the Edmonston Drive Bridge, between Rockville Pike (Maryland Route 355) and Lewis Avenue.

The eight-month-long project is scheduled to begin the week of July 16 and will include cleaning and painting; concrete abutment and pier repair; and concrete crack sealing on the bridge’s underside. The second phase will include concrete deck repair on the topside of the bridge, which provides a critical link between the eastern and western portions the city.

While the bridge is structurally sound, the repairs are part of the city’s ongoing Bridge Rehabilitation Program, which inspects long-span bridges every two years and prioritizes repairs based on structural improvements recommended in inspection reports.

During the first phase, which is expected to last 80 working days, short-term traffic impacts will require periodic lane closures weekdays between 9 a.m. and 3 p.m. One lane of the three-lane bridge will be closed for the duration of work on the bridge’s topside, which is expected to last about 50 working days. At least one sidewalk across the bridge will be open at all times.

The city’s contractor will install variable message signs at least two weeks before construction alerting motorists to upcoming traffic impacts.
