Allegheny Islands State Park

The BladeRunners Ice Complex was a group of ice hockey rinks and sports facilities which were located in Western Pennsylvania.

The Allegheny River Turnpike Bridge carries Interstate 76 (Pennsylvania Turnpike) over the Allegheny River. The structure features a pair of twin 2,350’ cast-in-place concrete segmental bridges. This is the first of its type in Pennsylvania. It was constructed between 2007 and 2010 and is the second bridge to stand on this site. The original truss bridge was built between 1949 and 1951 by the engineering firm Modjeski & Masters; the crossing predates the Interstate System by several years. The replacement bridge was designed by the engineering firm Figg and built by Walsh Construction. The purpose of the new structure was to increase the capacity of traffic from two lanes in each direction to three; this was done to eliminate a bottleneck at the exit with Pennsylvania Route 28, which branches off at the bridge approach on the Harmar side of the river.[1] The replacement eastbound bridge opened in November 2009. It carried both eastbound and westbound traffic across the Allegheny River until the project was finished one year later. On Tuesday, July 13, 2010, just after 10 a.m., the old steel structure of the Allegheny River Bridge was imploded with controlled demolition explosives. Roadway traffic was stopped for approximately 15–20 minutes, and river traffic was stopped for 24 hours for cleanup of the debris from the bridge.

The Bessemer & Lake Erie Railroad Bridge is a truss bridge that carries the Canadian National Railway's Bessemer and Lake Erie Railroad division across the Allegheny River between the Pittsburgh suburbs of Plum and Harmar Township, Pennsylvania. In 1897, a single-track trestle and viaduct was built on this site; in 1918, the original piers were doubled in width, the current double-tracked structure built alongside, and then slid into place. The original north trestle approach was buried in slag dumped from an adjacent temporary filling trestle.

Harmar Township is a township in Allegheny County, Pennsylvania, United States. It contains the communities of Acmetonia, Harmarville, Harmar Heights, and Chapel Downs. The population was 3,136 at the 2020 census. The township was named after Harmar Denny, a U.S. congressman and son of Ebenezer Denny.

The University of Pittsburgh Applied Research Center (U-PARC) is a one-million-square foot (93,000 m2), high-security research park campus of the University of Pittsburgh. Comprising 53 buildings situated on over 85 acres (0.34 km2), U-PARC is located 14 miles (23 km) from Downtown Pittsburgh in Harmar Township, Pennsylvania adjacent to the Route 28 expressway and Interstate 76, the Pennsylvania Turnpike.It was founded as the research laboratories of Gulf Oil in 1933 and moved to Harmar Township in 1935. It served many decades as one of the leading industrial research centers in the world, with labs engaging in petroleum, chemical, polymer, refining, and nuclear research. At its peak, it employed over 2,000 scientists and engineers and had an annual budget of $100 million ($272 million in 2022 dollars). Upon Gulf Oil's acquisition by Chevron Oil in 1985, the research park was donated to the University of Pittsburgh in order to keep the center open for the benefit of the region. U-PARC is home to more than 100 different companies from around the world, including several Fortune 500 Companies. In addition, the university's Swanson School of Engineering maintains laboratories and its Manufacturing Assistance Center at the site. It also serves as the home to the School of Health and Rehabilitation Sciences' Masters of Science program in Physician Assistant Studies.

The 1951 PGA Championship was the 33rd PGA Championship, held June 27 to July 3 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh. Sam Snead won the match play championship, 7 & 6 over Walter Burkemo in the Tuesday final; the winner's share was $3,500 and the runner-up's was $1,500.It marked the first time the PGA Championship returned to a venue; Oakmont had hosted in 1922 (at the time, it had also hosted two U.S. Opens and three U.S. Amateurs). It was the third and final win for Snead in the PGA Championship, and the fifth of his seven major titles. At age 39, he was the oldest at the time to win the PGA Championship, passing his old record of two years earlier. Burkemo won the title in 1953 and was runner-up again in 1954. Defending champion Chandler Harper lost in the first round to Jim Turnesa in a match that went to 23 holes. Turnesa, the runner-up to Snead back in 1942, won the title following year in 1952, and displaced Snead as the oldest champion by a few months. Snead's win was the last by a former champion for twenty years, until Jack Nicklaus won his second PGA Championship in 1971. Claude Harmon, Lloyd Mangrum, and Pete Cooper tied for the lowest score in the stroke play qualifier at 142 (−2). Harmon won the $250 medalist prize on the third hole of a sudden-death playoff.The British Open in 1951 was held in the first week of July in Northern Ireland. Its mandatory two-day qualifier was held the same days as the PGA's semifinals and finals, which prevented participation in both events.

The 1978 PGA Championship was the 60th PGA Championship, played August 3–6 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh. John Mahaffey won his only major championship in a sudden-death playoff over Jerry Pate and Tom Watson.Watson led the tournament each day and held a five-shot lead after 54 holes, but he faltered on Sunday with a 73 (+2) in his best opportunity for a PGA Championship, the only major he has never won. Pate had a four-foot (1.3 m) putt for a par and the victory on the 72nd hole, but it lipped out. After opening with a four-over 75 on Thursday, Mahaffey rebounded to go 12-under for the next three rounds, including a five-under 66 in the final round to gain the seven strokes on Watson. He had a history of hard luck in majors: at the U.S. Open, he lost the 18-hole playoff in 1975 and was the 54-hole leader in 1976, won by tour rookie Pate. Mahaffey broke that streak when he birdied the second extra hole to win the playoff at Oakmont. It was the second of three consecutive playoffs at the PGA Championship. Like Arnold Palmer, Watson won numerous majors but never the PGA Championship, the only leg missing for a career grand slam. At this time he had won three of his eight majors; his next best finish at the PGA Championship came fifteen years later in 1993, placing fifth at Inverness. Pate finished in the top five for the third straight year (and would again the next year) but never won another major. Jack Nicklaus, age 38, shot a 79 in the first round and missed the cut by five strokes in one of his worst performances in a major. Four-time champion Nicklaus was a pre-tournament favorite: in his previous majors at Oakmont (two U.S. Opens), he won in 1962, his first major and first win as a professional, and tied for fourth in the 1973. At the previous year's PGA Championship at Pebble Beach, he finished third, one stroke out of the playoff. This was the eighth major held at Oakmont and its third PGA Championship; the previous two in 1922 and 1951 were match play events.

The 2007 United States Open Championship was the 107th U.S. Open, held June 14–17 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh.Ángel Cabrera won his first major championship, one stroke ahead of runners-up Jim Furyk and Tiger Woods, who were unable to birdie the 72nd hole to force a Monday playoff. Cabrera's victory marked the first U.S. Open won by an Argentine or a South American. It was the first of his two major titles; he won the Masters in a playoff in 2009. This was the eighth U.S. Open and eleventh professional major held at Oakmont.

The 1994 U.S. Open was the 94th U.S. Open, held June 16–20 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh. Ernie Els, age 24, won the first of his four major titles on the second sudden-death hole to defeat Loren Roberts, after Colin Montgomerie was eliminated in an 18-hole playoff. (Both Roberts and Montgomerie were winless in major championships, but each won several senior majors while on the Champions Tour.) It was the seventh U.S. Open and tenth major held at Oakmont, and was Arnold Palmer's final U.S. Open as a participant.

The 1927 U.S. Open was the 31st U.S. Open, held June 14–17 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh. Tommy Armour defeated Harry Cooper in an 18-hole playoff to win the first of his three major titles. The surprise second round leader was amateur Jimmy Johnston, who won the U.S. Amateur two years later in 1929. In the third round on Thursday morning, he suffered two double bogeys on the front-nine, carded an 87 (+15), and finished in 19th place. Gene Sarazen, Walter Hagen, Bill Mehlhorn, and Emmet French were all in contention in the final round, but only French managed to break 40 on the back nine. Tommy Armour shot a final round 76 and 301 total, while Harry Cooper shot 77. Armour needed a 10-foot (3 m) putt for birdie on the par-4 18th to tie Cooper and force a playoff. Neither player managed to break par during any round in the tournament.Both players were tied after nine holes of the Friday playoff, even though they only halved one hole. Cooper then took a two-shot lead, but an Armour birdie at 13 and a Cooper bogey at 15 brought the match to all square. On the 16th, Cooper found a bunker off the tee and recorded a double bogey, while Armour made par to gain a two-stroke advantage did not relinquish. Armour finished with a 76 to Cooper's 79.Armour's winning score of 301 was the highest since 1919, and the last time the winning score exceeded 300 strokes. Only one round under 70 was recorded, Al Espinosa's 69 in the final round. After Armour, no foreign-born player won the U.S. Open for another 38 years, until Gary Player in 1965. England's Ted Ray, the 1920 champion, played in his first Open since his win; it would also be his last. The 12th hole at Oakmont measured 621 yards (568 m), the longest in U.S. Open history until 1955. While Armour won two more majors, Cooper never won one. His 31 PGA Tour victories are the most by a player without a major win, and he is often cited as the "best player to never win a major." Defending champion Bobby Jones and Eddie Jones shared low-amateur honors and tied for eleventh. It was the only time in his eleven U.S. Open appearances that Bobby Jones finished outside the top ten. This was the first U.S. Open held at Oakmont, which hosted its ninth in 2016. It has also hosted three PGA Championships; the first in 1922 was a match play event won by Gene Sarazen. This was the last U.S. Open to commence on Tuesday; the following year the first round was scheduled for Thursday.

The 1983 U.S. Open was the 83rd U.S. Open, held June 16–20 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh. Larry Nelson won the second of his three major titles, and only U.S. Open, one stroke ahead of defending champion Tom Watson.Watson and Seve Ballesteros shared the 54-hole lead, with Nelson a stroke back. Nelson was 7-over for the championship after four holes in his third round, but then played the final fourteen holes on Saturday in 7-under to get to even-par 213, one shot behind the co-leaders. Watson was attempting to become the first to successfully defend a U.S. Open title in over thirty years, last achieved by Ben Hogan in 1951. In the final round, Watson opened with a front-nine 31 to open up a three-stroke lead over Nelson, who shot 33. Nelson tied Watson with a birdie at 14 after Watson had bogeyed 10 and 12. A storm came through Oakmont around 5:30 p.m., which postponed play to the following morning. Watson was on the 14th green, Nelson on the 16th tee, tied at four-under for the championship.On Monday morning, Nelson holed a 62-foot (19 m) birdie putt at the par-3 16th, but then three-putted at the 18th for bogey. Nelson finished at four-under 280 total and waited for Watson. After he failed to save a par from a bunker at the 17th, Watson was one stroke behind Nelson. Watson needed a birdie at 18 to tie but his approach flew over the green. Nelson became the winner when Watson failed to hole out his chip shot. Nelson established a new tournament record with 132 strokes over the last 36 holes, breaking Gene Sarazen's 51-year-old mark. It was the second consecutive runner-up finish at Oakmont for Watson, who lost a sudden-death playoff to John Mahaffey five years earlier at the PGA Championship in 1978. Arnold Palmer made his last cut in a U.S. Open here and tied for 60th place. He played the Open just once more, in 1994 when he was granted a special exemption when it returned to Oakmont. Future major champion Paul Azinger made his major championship debut but missed the cut. Johnny Miller, the champion when the Open was last played at Oakmont in 1973, battled health issues, and also missed the cut. This was the sixth U.S. Open at Oakmont, and ninth major championship. Ticket prices were $24 per day, cash only; practice days were $14.

The 1922 PGA Championship was the fifth PGA Championship, held August 14–18 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh. The match play field of 64 competitors qualified by sectional tournaments. This was the first PGA Championship with a field of 64 in the bracket; the previous four had fields of 32 players. In the Friday final, Gene Sarazen defeated Emmet French, 4 & 3.Sarazen, age 20, also won the U.S. Open a month earlier near Chicago. Defending champion Walter Hagen did not enter this year due to exhibition engagements; the two champions met the following year in the finals, won by Sarazen. This was the first of twelve major championships at Oakmont; three PGA Championships and nine U.S. Opens through 2016. It has hosted the U.S. Amateur five times and the U.S. Women's Open twice. The PGA Championship returned in 1951 and 1978. Sarazen was the first of four players in history to win the U.S. Open and the PGA Championship in the same calendar year. He was followed by Ben Hogan in 1948 and Jack Nicklaus in 1980. Through 2012, Tiger Woods is the last to win both, in 2000, part of his Tiger Slam of four consecutive majors.
