Parkville Ramp to MD 147 Closes to Drivers

The Maryland State Highway Administration will close the westbound I-695 outer loop exit ramp to northbound MD 147 in Parkville from 8 p.m. Friday, November 6, to 8 a.m. Sunday, November 8, while contractor crews install a new underground drainage pipe. Drivers will be detoured via MD 41 Perring Parkway and the I-695 inner loop.

Why it matters

The closure affects commuters and travelers who use the I-695 outer loop to reach northbound MD 147 over a weekend, so planning an alternate route in advance can save time. Crews are completing the drainage work as part of a broader Transportation Systems Management and Operations project that enables part-time shoulder use from I-70 to MD 43.

The closure window runs daily from 8 p.m. to 8 a.m. across the weekend, and the broader project enables part-time shoulder use along I-70 to MD 43. Motorists needing roadside assistance can dial #77.

The players

Maryland State Highway Administration

The Maryland State Highway Administration is the state agency responsible for designing, building, and maintaining state highways, including the I-695 and MD 147 corridors affected by this closure.

Concrete General Inc.

Concrete General Inc. is a Gaithersburg, Maryland, contractor serving as lead contractor on the project installing the new drainage pipe.

The details

The ramp from westbound I-695 outer loop to northbound MD 147 closes while crews install a new underground drainage pipe. Crews guide drivers with digital message boards, temporary traffic signs, and barrels, and a single right lane closure on the outer loop from US 1 Belair Road to MD 41 runs alongside the ramp closure.

Friday, November 6, 2026, 8 p.m.: ramp closure and single right lane closure begin.
Saturday, November 7, 2026, 8 p.m.: double right lane closure begins on the I-695 outer loop.
Sunday, November 8, 2026, 8 a.m.: ramp and lane closures end.

Roadmap

The drainage work supports the Maryland State Highway Administration's Transportation Systems Management and Operations project, which enables part-time shoulder use on I-695 from I-70 to MD 43. This weekend closure is one step in expanding that operational approach across the Baltimore Beltway.

Drivers heading from the I-695 outer loop to northbound MD 147 should plan the detour via MD 41 Perring Parkway and the I-695 inner loop during the closure window. Commuters passing the single and double right lane closures between US 1 and MD 41 should expect slower travel through the work zone.

The takeaway

Checking the Maryland State Highway Administration's project updates before a weekend drive can help you avoid delays from ramp and lane closures. Keeping roadside assistance at #77 in mind is useful if a breakdown occurs during detours.

What happens next

The ramp and lane closures are scheduled to reopen at 8 a.m. Sunday, November 8, 2026, and will be rescheduled to the next possible weekend if bad weather delays the project.
