The Maryland Department of Transportation’s State Highway Administration (SHA) advises motorists who travel on MD 193 (University Boulevard) or I-495 (Capital Beltway) in Silver Spring that upcoming lane closures will impact overnight travel for the next month.
A 161-foot, 175-ton crane will be used to lift the steel beams for a new bridge and crews will work above the I-495 lanes to tighten the steel beam bolts. SHA will work on the steel beams over the Outer Loop first. Once all Outer Loop beam work is complete, crews will repeat the process to insert beams over the Inner Loop.
Work began this month and will continue each night through early March (weather permitting). SHA is closing the lanes on the Inner and Outer Loops between exit 28 (MD 650/New Hampshire Avenue) and exit 30 (US 29/Colesville Road) at the following times:
- One lane at 9 p.m.;
- Two lanes at 10 p.m.; and
- Three lanes at midnight.
The work also requires intermittent 15-minute complete lane closures between midnight and 4 a.m. All travel lanes will reopen each day no later than 5 a.m. Drivers should consider MD 650 or US 29 as alternate routes during the overnight lane closures.
