The section of the Custis Trail that goes under the I-66 underpass near Bon Air park will once again close overnight next week so a protective covering can be installed, according to Arlington County Department of Parks, Recreation and Cultural Resources.

The trail was closed at night for four days this week for similar work.

The trail will close from 9 p.m. to 5 a.m. on Monday, Tuesday and Wednesday nights in order to allow for the installation of a covering that that will protect riders from debris falling from the future widening of the overpass, according to the parks department. Arlington County Parks recommends walking bikes through that section of the trail while the work is ongoing.
