J. E. Greiner Company was a Baltimore, Maryland-based civil engineering firm specializing in bridge design.
The firm was founded in 1908 by former Baltimore and Ohio Railroad bridge engineer John Edwin Greiner (February 24, 1859 – November 15, 1942) [1] and led by Greiner and his associate Hershel Heathcote Allen. [2] The firm was later known as Greiner Engineering and opened a second office in Chicago, apparently in connection with its work on the Calumet Skyway. [3] In 1995, the firm was acquired by URS Corporation, now part of AECOM.
The firm designed several notable bridges and also prepared transportation planning studies, the first of which was Maryland's Primary Bridge Program for the Maryland State Roads Commission in 1938. [2] Later studies included Transportation Plans for Washington for Washington, D.C. in 1946, and Expressway System for Metropolitan Providence for Rhode Island, in 1947, both with De Leuw, Cather & Company.
U.S. Route 1 or U.S. Highway 1 (US 1) is a major north–south United States Numbered Highway that serves the East Coast of the United States. It runs 2,370 miles (3,810 km) from Key West, Florida, north to Fort Kent, Maine, at the Canadian border, making it the longest north–south road in the United States. US 1 is generally paralleled by Interstate 95 (I-95), though US 1 is significantly farther west and inland between Jacksonville, Florida, and Petersburg, Virginia, while I-95 is closer to the coastline. In contrast, US 1 in Maine is much closer to the coast than I-95, which runs farther inland than US 1. The route connects most of the major cities of the East Coast from the Southeastern United States to New England, including Miami, Jacksonville, Augusta, Raleigh, Richmond, Washington, D.C., Baltimore, Philadelphia, Newark, New York City, New Haven, Providence, Boston, and Portland.
Interstate 95 (I-95) is the main north–south Interstate Highway on the East Coast of the United States, running from U.S. Route 1 (US 1) in Miami, Florida, north to the Houlton–Woodstock Border Crossing between Maine and the Canadian province of New Brunswick. The highway largely parallels the Atlantic coast and US 1, except for the portion between Savannah, Georgia, and Washington, D.C., and the portion between Portland and Houlton in Maine, both of which follow a more direct inland route.
Elkridge is an unincorporated community and census-designated place (CDP) in Howard County, Maryland, United States. The population was 15,593 at the 2010 census. Founded early in the 18th century, Elkridge is adjacent to two other counties, Anne Arundel and Baltimore.
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States. It operated as B&O from 1830 until 1987, when it was merged into the Chessie System; its lines are today controlled by CSX Transportation.
The Washington–Baltimore combined metropolitan statistical area is a statistical area including the overlapping metropolitan areas of Washington, D.C. and of Baltimore. The region includes Central Maryland, Northern Virginia, three counties in the Eastern Panhandle of West Virginia, and one county in south-central Pennsylvania. It is the most educated, highest-income, and third-largest combined statistical area in the United States behind New York City–Newark, NJ and Los Angeles–Long Beach.
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.
Interstate 895 (I-895) is an auxiliary Interstate Highway in the US state of Maryland. Known as the Harbor Tunnel Thruway, the highway runs 11.44 miles (18.41 km) between one junction with I-95 in Elkridge and another interchange with I-95 on the east side of Baltimore. I-895 is a toll road that crosses the Patapsco River estuary via the Baltimore Harbor Tunnel, connecting U.S. Route 1 (US 1), I-695, and the Baltimore–Washington Parkway in the southwestern suburbs of Baltimore with US 40 on the east side of Baltimore. In conjunction with a pair of spurs, unsigned I-895A and I-895B, I-895 provides access to the tunnel from I-97 and Maryland Route 2 (MD 2) in Glen Burnie. The highway is designed for through traffic by having partial interchanges that require vehicles from almost all starting points to pass through the tunnel and the tunnel toll plaza, where a $1.40-$6.00 toll is charged to passenger vehicles, before exiting the facility.
Interstate 695 (I-695) is a 51.46-mile-long (82.82 km) auxiliary Interstate Highway that constitutes a beltway extending around Baltimore, Maryland, United States. I-695 is officially designated the McKeldin Beltway but is colloquially referred to as either the Baltimore Beltway or 695. The route is an auxiliary route of I-95, intersecting that route southwest of Baltimore near Arbutus and northeast of the city near White Marsh. It also intersects other major roads radiating from the Baltimore area, including I-97 near Glen Burnie, the Baltimore–Washington Parkway near Linthicum, I-70 near Woodlawn, I-795 near Pikesville, and I-83 in the Timonium area. The 19.37-mile (31.17 km) portion of the Baltimore Beltway between I-95 northeast of Baltimore and I-97 south of Baltimore is officially Maryland Route 695 (MD 695) and is not part of the Interstate Highway System but is signed as I-695. The Francis Scott Key Bridge that crossed over the Patapsco River was included in this section of the route before the bridge's collapse on March 26, 2024. The bridge and its approaches were maintained by the Maryland Transportation Authority (MDTA), while the remainder of the Baltimore Beltway is maintained by the Maryland State Highway Administration (MDSHA).
Interstate 295 (I-295) also known as the Anacostia Freeway, is a six-mile (9.7 km) auxiliary Interstate Highway in the US state of Maryland and in Washington, D.C.. It connects I-95/I-495 and Maryland Route 210 near the Potomac River to I-695 and District of Columbia Route 295 (DC 295) in the Anacostia neighborhood of Washington, D.C.
Paul Philippe Cret was a French-born Philadelphian architect and industrial designer. For more than thirty years, he taught at a design studio in the Department of Architecture at the University of Pennsylvania.
The Hanover Street Bridge, officially the Vietnam Veterans Memorial Bridge, is a double leaf bascule bridge crossing the middle branch of the Patapsco River along Hanover Street in Baltimore, Maryland.
Interstate 95 (I-95) is an Interstate Highway running along the East Coast of the United States from Miami, Florida, north to the Canada–United States border at Houlton, Maine. In Maryland, the route is a major highway that runs 110.01 miles (177.04 km) diagonally from southwest to northeast, entering from the District of Columbia and Virginia at the Woodrow Wilson Bridge over the Potomac River, northeast to Maryland's border with Delaware near Elkton. It is the longest Interstate Highway within Maryland and is one of the most traveled Interstate Highways in the state, especially between Baltimore and Washington, D.C., despite alternate routes along the corridor, such as the Baltimore–Washington Parkway, U.S. Route 1 (US 1), and US 29. I-95 also has eight auxiliary routes in the state, the most of any state along the I-95 corridor. Portions of the highway, including the Fort McHenry Tunnel and the Millard E. Tydings Memorial Bridge, are tolled.
Interstate 90 (I-90) in the US state of Illinois runs roughly northwest-to-southeast through the northern part of the state. From the Wisconsin state line at South Beloit, it heads south to Rockford before heading east-southeast to the Indiana state line at Chicago. I-90 traverses 124 miles (200 km) through a variety of settings, from farmland west of the Fox River Valley through the medium-density suburbs west of O'Hare International Airport, through Downtown Chicago, and through the heart of the industrial southeast side of Chicago before entering Indiana.
Interstate 70 (I-70) is a part of the Interstate Highway System that runs from Cove Fort, Utah, to Woodlawn just outside of Baltimore, Maryland. In Maryland, the Interstate Highway runs 91.85 miles (147.82 km) from the Pennsylvania state line in Hancock east to the Interstate's eastern terminus at its junction with I-695. I-70 is the primary east–west Interstate in Maryland; the Interstate Highway connects Baltimore—and Washington, D.C., via I-270—with Western Maryland. The Interstate serves Frederick and Hagerstown directly and provides access to Cumberland via its junction with I-68 at Hancock. I-70 runs concurrently with its predecessor highway, U.S. Route 40 (US 40), from Hancock to Indian Springs in Washington County and from Frederick to West Friendship in Howard County.
Zantzinger, Borie and Medary was an American architecture firm that operated from 1905 to 1950 in Philadelphia. It specialized in institutional and civic projects.

Brooklyn is one of the southernmost neighborhoods in Baltimore, Maryland. It is located near Anne Arundel County along Governor Ritchie Highway which is also Maryland Route 2. Its main roads are South Hanover Street,, Potee Street, and East Patapsco Avenue, Sixth Street, Tenth Street, and West Bay Avenue which borders the neighboring Curtis Bay community to the east, running through Bay Brook Park, which separates the two. South Hanover Street also serves as the dividing line between east–west streets in Brooklyn, as Charles Street does not exist here.
Charles Center is a large-scale urban redevelopment project in central Baltimore's downtown business district of the late 1950s and early 1960s. Beginning in 1954, a group called the "Committee for Downtown" promoted a master plan for arresting the commercial decline of central Baltimore. In 1955, the "Greater Baltimore Committee", headed by banker and developer James W. Rouse, joined the effort. A plan was developed by noted American urban planner and architect David A. Wallace, (1917−2004), strongly supported by Mayors Thomas L. J. D'Alesandro, Jr. (1947−1959) and Theodore R. McKeldin, and many in their administrations, which formed the basis of a $25 million bond issue voted on by the citizens of Baltimore City during the municipal elections in November 1958. The architects' view of the overall Charles Center Redevelopment Plan with the conceptions of possible buildings, lay-out and plan that was publicized to the voters that spring and summer before, only slightly resembles the actual buildings and designs that later were really constructed by the mid-1970s.
