The roadways and the park are administered by the Massachusetts Department of Conservation and Recreation, a successor to the Metropolitan District Commission, which oversaw their construction.
The Dedham Parkway, a two-lane road, extends southwest from this junction, exiting the park soon afterward.
It passes a junction with Georgetowne Drive, and then with Alwin Street, before crossing into Dedham and reaching its southern terminus, a junction with Harding Terrace (the cross street), and Dedham Boulevard (its southerly continuation).
It eventually skirts the southwestern edge of the reservation, passing through an intersection with Smithfield Road and Alwin Street.
River Street provides a connection (on the far side of Mill Pond Reservation) to the Neponset Valley Parkway.
