St. Johns Signal Tower Gas Station
The St. Johns Signal Tower Gas Station, located in the St. Johns neighborhood of north Portland, Oregon, is listed on the National Register of Historic Places.
 It was built and opened in 1939 as a gas station for the Signal Oil Company.
 It was in operation as a gas station until 1984, but changed brand from Signal Gas to Hellman's Golden Eagle Gas Station in 1954 and, in turn, became a Chevron station in 1965.
 In 1984, it was converted into a florist shop, the gasoline tanks being decommissioned at that time and filled with concrete, and it functioned in that capacity until 2002.
 The structure was added to the National Register in 2003. Colonial Beacon Gas Station
The Colonial Beacon Gas Station is a historic gas station at 474 Main Street in Stoneham, Massachusetts.
 It was built c. 1922 by the Colonial Oil Company to be a flagship station in their chain of filling stations.
 The concrete and stucco building was designed by the Boston firm of Coolidge & Carlson.
 It has two main sections: an octagonal section that once served as a drive-through filling area, and a rectangular service area to its left.
 Corinthian columns originally supported the octagonal section; these have since been covered over or replaced.
 The octagonal section is topped by a round dome, at whose apex is a small pillared section that was once topped by a grillwork globe that housed a light.
 This light, when illuminated, became the beacon which gives the station its name.
 The service area and pumping bay have a band of starburst panels that run along the top of the flat roofed service area and around the base of the pumping area dome. New Ulm Oil Company Service Station
The New Ulm Oil Company Service Station is a historic gas station in New Ulm, Minnesota.
 The private, commercial structure was placed on the National Register of Historic Places (NRHP) on December 31, 1979.

The U-Drop Inn, also known as Tower Station and U-Drop Inn and Tower Café, was built in 1936 in Shamrock, Texas along the historic Route 66 highway.
 Inspired by the image of a nail stuck in soil, the building was designed by J. C. Berry.
 An unusual example of art deco architecture applied to a gas station and restaurant, the building features two flared towers with geometric detailing, curvilinear massing, glazed ceramic tile walls, and neon light accents.
 It has traditionally held two separate business: "Tower Station", a gas station on the western side, and the "U-Drop Inn", a café on the eastern side.
 Though it has passed hands several times in its history, the building has consistently housed the same types of businesses it was originally constructed for. InterNorth
InterNorth Inc. was a large energy company headquartered in Omaha, Nebraska, in the United States, specializing in natural gas pipelines but also a force in the plastics industry, coal and petroleum exploration and production.
 They operated the largest natural gas pipeline in North America (approximately 36,000 miles of pipeline) formed in 1979 as a holding company for Northern Natural Gas Company (founded in 1931), Northern Liquid Fuels Company, Northern Petrochemicals Company, Northern Propane Gas Company, Northern Border Pipeline Company, and People's Natural Gas.
 InterNorth was briefly renamed HNG/Internorth in 1985, following its takeover of Houston Natural Gas Company.
 It was renamed Enteron briefly, before the naming people discovered there was a conflict.
 The name was changed to Enron Corporation just six months later. Gardner and Tinsley Filling Station

Ambler's Texaco Gas Station, also known as Becker's Marathon Gas Station, is a historic filling station located at the intersection of Old U.S. Route 66 and Illinois Route 17 in the village of Dwight, Illinois, United States.
 The station has been identified as the longest operating gas station along Route 66; it dispensed fuel for 66 continuous years until 1999.
 The station is a good example of a domestic style gas station and derives its most common names from ownership stints by two different men.
 North of the station is an extant outbuilding that once operated as a commercial icehouse.
 Ambler's was the subject of major restoration work from 2005–2007, and reopened as a Route 66 visitor's center in May 2007.
 It was added to the U.S. National Register of Historic Places in 2001.
