State Highway Administration Work on I-495 (Beltway) in Montgomery County Starting Sunday, April 16, Likely Will Cause Overnight Disruptions Through Late Spring

The Maryland Department of Transportation State Highway Administration will begin milling and paving at several locations on I-495 in Montgomery County starting Sunday, April 16. Work will take place nightly from 9 p.m.-5 a.m. Weather permitting, all work will be complete by late spring.

During work periods, motorists can expect lane shifts and lane closures to establish a safe work zone. The roadwork can cause delays.

Work on the following locations will directly impact traffic in Montgomery County:
  • I-495 (Capital Beltway) Inner Loop (eastbound) between the bridge over Northwest Branch east of MD 193 (University Boulevard) and the Prince George’s County.
  • I-495 Outer Loop (westbound) between MD 193 and Seminary Road.
  • I-495 Inner Loop (eastbound) between the Seminary Road bridge and just east of US 29 (Columbia Pike).
