Gulf Freeway

The stretch of I-45 connecting Galveston with Houston is known as the Gulf Freeway. It was the first freeway built in Texas--opened in stages beginning on October 1, 1948, thru a full completion to Galveston in 1952, as part of U.S. Highway 75.

This grade separation was completed from Houston to Almeda-Genoa Road (exit 34) in June 1959, Farm to Market Road 1959 (exit 30) in October 1964, Farm to Market Road 518 (exit 23) in December 1970, and Farm to Market Road 1764 (exit 15) in 1976. Farm to Market Road 1959 is a state highway in southeast Harris County in the U Farm to Market Road 1764, or FM 1764, is a state Highway in the U As the section beyond FM 1764 into Galveston had already been rebuilt,^[28][24] this marked the completion of the Gulf Freeway as an actual freeway. ^[16]

As the first freeway in Texas, the standards of the Gulf Freeway soon became inadequate, with poor sight lines and little room to merge when entering. It also attracted development, such as Gulfgate Shopping City, the first mall in the Houston area, the Manned Spacecraft Center, and many residential developments. The Lyndon B Johnson Space Flight Center ( "JSFC") is the National Aeronautics and Space Administration 's center for A residential development (sometimes simply called a subdivision) is typically a Piece of Property that is divided into lots with Heavy congestion began to affect the freeway by the early 1960s; two roughly parallel freeways - the Harrisburg Freeway and Alvin Freeway - were proposed at that time to relieve the traffic, but were not built. State Highway 35, or SH 35, is a largely north-south highway in southeastern and southern Texas between Houston, junction of I-45 on the southeast A short project to widen the road to six lanes between I-610 and Sims Bayou was completed in 1960, and ramp meters were installed in 1966. A ramp meter, ramp signal or metering light is a device usually a basic Traffic light or a two-phase (red and green no yellow light together The I-610 interchange was rebuilt with direct connections for most movements in 1975. Plans to reconstruct the freeway near downtown began in 1972, taking about 170 houses and 22 businesses from the southwest side for the room to expand the main lanes and add parallel lanes for the Alvin Freeway. Local opposition was unsuccessful at stopping the project, and construction on this segment, and others to the southeast, took place in the 1980s. The lanes were shifted outward to make room for the transitway, which opened to I-610 on May 16, 1988. Events 1204 - Baldwin IX Count of Flanders is crowned as the first Emperor of the Latin Empire. Year 1988 ( MCMLXXXVIII) was a Leap year starting on Friday (link displays 1988 Gregorian calendar) These lanes were inspired by the similar ones on the Shirley Highway in the Washington Metropolitan Area. The Henry G Shirley Memorial Highway was the first limited access freeway in the U The Washington DC Metropolitan Area, formally known as the Washington-Arlington-Alexandria DC-VA-MD-WV MSA is a U ^[29] That year also marked the end of the reconstruction inside I-610, along with the elevated distribution lanes alongside the main lanes near downtown; the first short piece of the Alvin Freeway was finally connected to these in 1999. This project gave I-45 its current configuration, mostly eight main lanes wide, from Sims Bayou past I-610 to Griggs Road in 1981, to Telephone Road in 1982, to Lockwood Drive in 1985, and finally to downtown in 1988. ^[16]

However, this was not the end of construction on the Gulf Freeway. The highway beyond I-610 to FM 1959, which had just been upgraded in the 1950s and 1960s, saw an extension of the transitway to a temporary end near FM 1959, widening to eight lanes, and a large stack interchange at the Sam Houston Tollway. A stack interchange is a free-flowing junction between two or more roads that allows turning in all directions Beltway 8 ( BW8) the Sam Houston Parkway, along with the Sam Houston Tollway, is a Beltway around the city of Houston Texas, This reconstruction was completed between Almeda-Genoa Road and College Avenue in 1991, between College Avenue and Sims Bayou in 1994, and finally, in 1997, there was no construction anywhere on the entire length of the freeway when the tollway interchange was opened, along with the widening between Almeda-Genoa Road and FM 1959. A 1999 study recommended widening the entire stretch from the Sam Houston Tollway to Galveston to at least eight lanes. Construction to replace the Galveston Causeway began in mid-2003,^[16] and work on a section through Webster, including a new interchange with the NASA Road 1 Bypass, began in mid-2007. The Galveston Causeway is a Causeway in Galveston Texas, United States. Webster is a city in Harris County, Texas, United States.

North Freeway (Houston to Conroe)

The last alignment of US 75 before the North Freeway was built left downtown Houston to the northwest on Main Street, turning north at Airline Drive, and then northwest along the present alignment of I-45, then known as Stuebner Airline Road, Shepherd Drive, and East Montgomery Road. ^[26] The freeway replacement was authorized in stages between May 1945 and June 1952, when the Texas Transportation Commission adopted plans for a freeway all the way between Houston and Dallas. The North Freeway name was adopted in 1956; an unsuccessful proposal in 1965 would have renamed it the Dallas Freeway. ^[31] The first short piece of the freeway to open crossed Buffalo Bayou, connecting the two one-way pairs from the north end of the Gulf Freeway with the south end of Houston Avenue. Buffalo Bayou is a main waterway flowing through Houston, in Harris County Texas, USA. A one-way pair or one-way couple is a pair of parallel usually One-way streets that carry opposite directions of a signed route or major Traffic flow or This was opened on December 12, 1955, and allowed US 75 to bypass its run on Main Street;^[27] it included interchanges with Allen Parkway and Memorial Drive.

The six-lane Pierce Elevated, which occupies half a block on the southwest side of Pierce Street, required the acquisition of a number of commercial properties; the cost prevented the full block from being used. This portion opened on August 18, 1967, connecting the Gulf and North Freeways and bypassing the "four-street distribution system", which remains in its original form to this day.

The first piece of the North Freeway to be built outside I-610 was an upgrade of existing US 75 on Stuebner Airline Road, between Airline Drive and Shepherd Drive, opened in December 1959. In April 1961, this was completed to the interchange with I-610, and on July 24, 1962 the downtown section was extended north to meet it.

Farm to Market Road 525, or FM 525 or Urban Road 525, is a State highway entirely inside the city of Houston Texas, United States The freeway as initially built had eight lanes (four in each direction) between downtown and I-610, six to Farm to Market Road 1960, and four north of FM 1960.

Like the Gulf Freeway, the North Freeway soon became congested. The oil boom of the 1970s resulted in large-scale residential development along the highway, most notably The Woodlands. A residential development (sometimes simply called a subdivision) is typically a Piece of Property that is divided into lots with The Woodlands is not a Census-designated place (CDP and large master-planned community of Montgomery and Harris counties in the U Since the corridor was strongly directional, with 65% of peak-hour traffic going in the peak direction, a 9. 6-mile (15. 4 km) contraflow lane for buses and other high-occupancy vehicles (HOV) was implemented later that decade, opening on August 28, 1979 between downtown and Shepherd Drive (exit 56B).

A hard shoulder, or simply shoulder, is a reserved area by the verge of a Road or Motorway. However, off-peak traffic was increasing, and construction began in 1983 on a more permanent reversible transitway in the median. This, the second transitway in Houston (a month after the one on the Katy Freeway), opened on November 23, 1984, replacing the contraflow lane.

Reconstruction of the main lanes and frontage roads to handle increased traffic began in 1982 just north of downtown. No lanes were added south of I-610, but the eight-lane cross section, with room for a transitway, was continued north as oonstruction progressed. Work was completed south of Airline Drive (exit 53) in about 1985, to Shepherd Drive (exit 56B) in 1987, and to Farm to Market Road 525 (exit 60A) in 1990; this last opening allowed the transitway to extend to just south of FM 525.

Schepps Freeway (Dallas) and to Richland

The Central Expressway was the first freeway in Dallas, built as a new alignment of US 75. NCX redirects here For the transport protein see Sodium-calcium exchanger. It first opened between San Jacinto Street and Fitzhugh Avenue in 1949, and soon stretched south to Hutchins. Hutchins is a city in Dallas County, Texas, United States. The population was 2805 at the 2000 census However, the stretch through downtown ran along the surface, as did the part south of the bridge over the Trinity River, due to diversion of funds to the north portion. The Trinity River is a 710-mile long river that flows entirely within the U ^[36] By the late 1950s, a bypass to the east of the downtown section was planned. ^[37] By the time construction reached Hutchins, in about 1955, the state decided to build further segments to full freeway standards. By 1961, the freeway was complete between Hutchins and the State Highway 14 split at Richland, except for the bypass around Corsicana, which was built ca. State Highway 14, or SH 14, runs from I-45 in Richland to SH 6 south of Bremond in east central Texas in the Richland is a town in Navarro County, Texas, United States. The population was 291 at the 2000 census Corsicana is a City in Navarro County, Texas, United States. It its located on Interstate 45 some fifty-five miles south of downtown 1964. ^[24][34] This freeway was mostly built along the existing US 75; one of the projects in Navarro County, near Corsicana, was the first Interstate project in Texas approved under the Federal-Aid Highway Act of 1956.

Reconstruction and widening to six lanes, from the Ellis-Navarro county line (between exits 243 and 244) north to State Highway 310 (exit 275), began in 1991. Ellis County is a County located in the US state of Texas. In 2000 its population was 111360 Navarro County is a County located in the US state of Texas.
