WASHINGTON — Hikers and bicyclists will enjoy improvements to a popular trail, but construction on Piney Branch Road at Sligo Creek Parkway might inconvenience some motorists in the months ahead.

Work is getting underway to build a pedestrian bridge over Sligo Creek. The nearly $2 million project will also include realigning the trail, and constructing sidewalks and ramps that comply with the Americans With Disabilities Act.

The State High Administration said the project could last until the end of the year.

Work crews will close one lane in both directions of Piney Branch Road at Sligo Creek Parkway weekdays between 9 a.m. and 3 p.m. during construction.

The trail will remain open while the work is going on.
