The #9  trolley line arrived in Ellicott City in 1899 and served the community for the next 55 years. This route was known for its scenic woodland views as the line dropped into the Patapsco River Valley.

In 1991, a century after it was constructed, Boy Scout Troop 456, organized the effort to clear and pave the #9 Trolley Line for a bike/hike trail as part of a very successful Eagle Scout project.

Today, the path is paved and features a section of boardwalk next to walls of rock that were hand-cut by the original builders.
