The West Farnam neighborhood or the Blackstone neighborhood in Omaha, Nebraska is located from Dodge Street on the north to Leavenworth Street on the south, Highway 75/Interstate 480 on the east to South 52nd Street on the west.
 In 1997, the Gold Coast Historic District was formed from the West Farnam neighborhood and the Park Place neighborhood, known today as Cathedral.
 Named for its principal thoroughfare, West Farnam was a prime real estate area in the first quarter of the 20th century.
 It is home to several historical landmarks, including houses, churches, and former hotels.
The Ak-Sar-Ben Bridge was a truss bridge that was the first road bridge to cross the Missouri River connecting Omaha, Nebraska and Council Bluffs, Iowa.
 It was replaced in 1966 by the Interstate 480 girder bridge.
Interstate 480 (I-480) is a 41.77 mi auxiliary Interstate Highway of I-80 that bypasses the city of Cleveland, Ohio, in the United States.
 I-480 is one of 13 auxiliary Interstate Highways the state.
 The western terminus of I-480 is an interchange with I-80 in North Ridgeville.
 Starting east through suburban Lorain County, I-480 enters Cuyahoga County.
 I-480 then approaches the Cleveland Hopkins International Airport, which serves as the primary airport for the Greater Cleveland area.
 After traversing Brooklyn and crossing the Cuyahoga River on the Valley View Bridge, the highway continues east towards the communities of Bedford and Twinsburg toward its eastern terminus at I-80 in Streetsboro.
 On its route, I-480 crosses interstates I-71, I-77 and I-271.
 In 1998, the Governor of Ohio, George Voinovich, gave I-480 the additional name of the "Senator John Glenn Highway", in honor of the former NASA astronaut and a U.S. Senator from Ohio for 24 years.
John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016) was a United States Marine Corps aviator, engineer, astronaut, and United States Senator from Ohio.
 In 1962 he became the first American to orbit the Earth, circling it three times.
State Route 10 (SR 10) is a state highway located in and around Cleveland, Ohio.
 The current routing of SR 10 was certified in 1934.
 The route's western terminus is in Eaton Township in Lorain County at the junction of U.S. Route 20, State Route 57 and State Route 301, where US 20 and SR 301 continue westbound on the freeway.
 In North Ridgeville, route 10 merges with Interstate 480 at the interstate's western terminus in North Ridgeville, and continues with the interstate briefly eastward.
 Just east of this junction, the route also has an interchange with Interstate 80 and the Ohio Turnpike via a connecting or spur road.
 SR 10 then becomes a grade-level road in North Ridgeville before heading into Cuyahoga County, and is known as Lorain Road.
 It then continues through the western suburbs of Cleveland and through the western part of Cleveland, as Lorain Avenue, terminating shortly after it crosses the Cuyahoga River at Gateway at Broadway Avenue/Ontario Street (U.S. Route 422, State Route 8, State Route 14, State Route 43, and State Route 87).
Jefferson Square was the last of three original public parks extant in Omaha, Nebraska.
 Bounded by North 15th, 16th, Chicago and Cass Streets, the park was dedicated November 25, 1865.
 It was razed by the city March 18, 1969 to make way for the construction of Interstate 480 in Downtown Omaha.
 Before that time it was the site of Omaha's first school, and considered for the location of the first Omaha Public Library and the Omaha Market House.
Currently the Interstate Highway System includes seven suffixed routes that are signed: the Interstate 35 split into Interstate 35E and Interstate 35W at Dallas-Fort Worth, Texas; a similar split into Interstate 35E and Interstate 35W at Minneapolis-St.
 Paul, Minnesota; as well as Interstate 69C, Interstate 69E and Interstate 69W in South Texas; in addition, Interstate 480N in Ohio exists and is designated as such on mile markers but is otherwise unsigned.
 However, there were once many more, as the three-digit Interstates were not designated until after all major routes were assigned numbers, including some short connections and spurs.
 (A few of the shortest, including I-190 and I-195, were assigned three-digit numbers almost immediately.)
 Most were not equal splits like on I-35, but had the main route continue through, and often the suffixed route never returned to its parent.
 In 1980, AASHTO abolished the majority of suffixes due to confusion, renumbering them as three-digit Interstates, but several that return to their parents were kept.
 For example, Interstate 15E has since become Interstate 215, but both I-35E/I-35W and I-69 splits still exist.
State Route 17 (SR 17) is an east–west highway in Northeast Ohio running from North Olmsted at State Route 10 to State Route 43 in Bedford Heights.
 The entire route has been paralleled by Interstate 480 and has junctions with this interstate via numerous cross streets such as Clague Road, Tiedeman Road, and Warrensville Center Road, and also via State Route 94 (State Road) and State Route 14 (Broadway Avenue).
 It also has two direct junctions with the interstate.
 State Route 17 provides access to many industrial and commercial areas in this area of Cleveland.
Interstate 480 (I-480) is a 4.90 mi auxiliary Interstate Highway that connects Interstate 80 in downtown Omaha, Nebraska, with Interstate 29 in Council Bluffs, Iowa.
 The portion of I-480 in Nebraska has been named the Gerald R. Ford Expressway, named in honor of the former President, who was a native of Omaha.
 For most of its length, I-480 is overlapped by a U.S. Highway; for 2 mi with U.S. Route 75 and for 1 mi with U.S. Route 6.
 I-480 includes the Grenville Dodge Memorial Bridge over the Missouri River.
State Route 291 (SR 291) is a 4.14 mi north–south state highway in the northeastern quadrant of the U.S. state of Ohio.
 The southern terminus of the highway is at a T-intersection with Fowles Road in Middleburg Heights, nearly 0.50 mi west of where Fowles Road meets U.S. Route 42.
 Its northern terminus is at a signalized T-intersection with SR 17 on the border between Brook Park and Cleveland, immediately west of where SR 17 passes underneath Interstate 71 south of Interstate 480.
 It is known locally as Engle Road through its entire length.
