Patapsco Regional Greenway

About the Patapsco Regional Greenway 

The Patapsco Regional Greenway envisions a 40-mile, shared-use trail running through the Patapsco Valley from Baltimore’s Inner Harbor to Sykesville in Carroll County. This trail, if completed, would pass through or near the communities of Cherry Hill, Baltimore Highlands, Halethorpe, Elkridge, Catonsville, Ellicott City, Oella, Daniels, Woodstock, Marriottsville, and Sykesville.

Parts of the 10-12 foot wide shared-use trail are already constructed and open for use:

  • Freedom Park Trail (Carroll County, 1.6 miles)
  • Grist Mill Trail (Baltimore County, 5.2 miles)
  • Gwynns Falls Trail at the Middle Branch (Baltimore City, 1.6 miles)
  • Gwynns Falls Trail at Ridgely’s Cove (Baltimore City, 1 mile)
  • Jones Falls Trail at the Inner Harbor (Baltimore City, 0.4 miles)
  • Waterfront Promenade (Baltimore City, 1.3 miles)
  • Port Covington Waterfront Parks (Baltimore City, 1.2 miles)

Remaining portions will be designed and constructed based on local priorities and funding availability.

Elkridge to Guinness Project

The Elkridge to Guinness Open Gate Brewery segment, approximately 2 miles in length, is undergoing preliminary (30%) design and will provide connections from Guinness Open Gate Brewery to Historic Elkridge and Patapsco Valley State Park.

The goals of this project are to:

  • build a low-traffic bicycle and pedestrian facility
  • improve access to the nearby natural environment
  • create a new gateway to downtown Elkridge to support economic development

As of June 2020, the design team considered many alignments and developed three (3) main alternatives. Primary design considerations included identifying optimal locations for crossing the Patapsco River, identifying optimal locations for crossing U.S. 1, safety, environmental impacts, and cost.

Elkridge to Guinness Project Partners

The 30% design phase is sponsored by Baltimore and Howard Counties and managed by the Baltimore Metropolitan Council. BMC has also convened a Steering Committee of property owners and primary stakeholders including MDOT State Highway Administration, Maryland Transportation Authority, Patapsco State Valley Park, Maryland Park Service, Diageo (owner of Guinness) and BGE to provide input on alignments, constraints, future amenities, etc.

Additionally, a small group of community members representing Friends of Patapsco Valley State Park, Patapsco Heritage Greenway, Greater Elkridge Community Association, and Baltimore Regional Transportation Board Public Advisory Committee serve on a community advisory group to provide input and support outreach to their members and interested parties.
