The Baltimore–Washington Parkway is a highway 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. Upon entering Baltimore, the Baltimore Department of Transportation takes over maintenance of the road and it continues north to an interchange with Interstate 95 (I-95). Here, the Baltimore–Washington Parkway ends and MD 295 continues north unsigned on Russell Street, which carries the route north into downtown Baltimore. In downtown Baltimore, MD 295 follows Paca Street northbound and Greene Street southbound before ending at US 40.

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.
