In 2019, we added a trail in Long Bridge Park and National Landing adjacent to the Potomac River. Many thanks go out the Crystal City Business Improvement District for planning and funding, to Adam Brady and his crew Arlington County Parks for installing the nest boxes, and to many VBS Arlington volunteers for building and monitoring the nest boxes.

Long Bridge Park is home to many nesting Tree Swallows. Tree Swallows are migratory and each year use these nest boxes.
