Georgetown was an independent municipality until 1871 when the United States Congress created a new consolidated government for the entire District of Columbia. A separate act, passed in 1895, repealed Georgetown's remaining local ordinances and renamed Georgetown's streets to conform with those in Washington, D.C.
The Baltimore–Washington Parkway is a controlled-access parkway in the U.S. state of Maryland, running southwest from Baltimore to Washington, D.C. The road begins at an interchange with U.S. Route 50 (US 50) near Cheverly in Prince George's County at the Washington, D.C., border, and continues northeast as a parkway maintained by the National Park Service (NPS) to MD 175 near Fort Meade, serving many federal institutions. This portion of the parkway is dedicated to Gladys Noon Spellman, a representative of Maryland's 5th congressional district, and has the unsigned Maryland Route 295 (MD 295) designation. Commercial vehicles, including trucks, are prohibited within this stretch. This section is administered by the NPS's Greenbelt Park unit. After leaving park service boundaries the highway is maintained by the state and signed with the MD 295 designation. This section of the parkway passes near Baltimore–Washington International Thurgood Marshall Airport.

The Clara Barton Parkway is a parkway in the U.S. state of Maryland and the District of Columbia. The highway runs 6.8 miles (10.9 km) from MacArthur Boulevard in Carderock, Maryland, east to Canal Road at the Chain Bridge in Washington. The Clara Barton Parkway is a two- to four-lane parkway that parallels the Potomac River and the Chesapeake and Ohio Canal (C&O) in southwestern Montgomery County, Maryland, and the far western corner of Washington. The parkway provides access to the communities of Cabin John and Glen Echo and several units of the Chesapeake and Ohio Canal National Historical Park. The Maryland portion of the George Washington Memorial Parkway was constructed from Carderock past Interstate 495 (I-495) to Glen Echo in the early to mid-1960s. The parkway was proposed to continue west to Great Falls and east to Georgetown. However, these proposals never came to fruition and the parkway was extended only to the Chain Bridge in the early 1970s. The Maryland portion of the George Washington Memorial Parkway was renamed in 1989 for Clara Barton, the founder of the American Red Cross, and whose original headquarters is located in Glen Echo.

The Olema Lime Kilns at Point Reyes National Seashore in California were built in 1850 on land leased from Mexican grantee Rafael Garcia by James A. Shorb and William F. Mercer, two San Francisco entrepreneurs. The kilns were reportedly fired only a few times, and have lain abandoned for some 140 years. They were apparently abandoned no later than 1855 after only a few firings, probably due to the poor quality, small limestone deposits and the financial depression of that year. They represent a Gold Rush era effort to establish a lime-producing industry in Marin County, only two years after cession of Alta California to the United States by Mexico. They consist of three long-abandoned, barrel-shaped stone vaults lying in ruins against a hillside on the east side of Olema Creek about five miles south of Olema and about 100 yards west of California State Highway 1.
