Matthew Henson State Park is a publicly owned greenway with recreational features that runs along Turkey Branch, a tributary of Rock Creek, in Montgomery County, Maryland.

[5] Purchased by the state in the 1950s,[6] the land was originally called the Rockville Facility, which would have connected to Montrose Parkway[5] as a spur to the proposed Washington Outer Beltway.

[10][11] The trail includes ten-foot-wide boardwalks to protect the most sensitive areas and solar-powered emergency cellular phones.

Then, after a cyclist was killed using the crossing in 2015, the state added a yellow, flashing light and signs alerting drivers.

They also upgraded to a "continental" crosswalk that is more visible to motorists, replaced the zig-zag crossing with a straight-line crossing in the median and installed “passive detection” — a system in which sensors detect pedestrians and bicyclists standing in the flat landing area and activate the pedestrian signal.
