Chengdu Metro opened

The Chengdu Metro is the rapid transit system of Chengdu, the capital of Sichuan, China. With the opening of Line 1 on 27 September 2010, the system consists of 12 subway lines and 1 light rail line. It has subsequently undergone rapid expansion. Since the opening of Lines 6, 8, 9, and 17 on 18 December 2020, the Chengdu Metro is the 4th longest metro system in the world. There are currently 12 operating subway lines totaling 518.5 km (322.2 mi) of track, and 1 tram line (Line T2). The Chengdu Metro serves over 8 million trips per day. As of 2021, about 2.2 million and 4.6 million people live within 500 and 800 metres (1,640 and 2,625 ft) of a subway station in Chengdu, respectively.

1995
Fred Hartman Bridge opened

The Fred Hartman Bridge is a cable-stayed bridge in the U.S. state of Texas spanning the Houston Ship Channel. The bridge carries 2.6 miles (4.2 km) of State Highway 146 (SH 146), between the cities of Baytown and La Porte (east of Houston). The bridge is also expected to carry State Highway 99 (SH 99) (Grand Parkway) when it is completed around Houston. It is the 77th largest bridge in the world. The construction cost of the bridge was $91.25 million. The bridge replaced the Baytown Tunnel (of depth clearance 40 feet or 12.2 m). The tunnel had to be removed when the Houston Ship Channel was deepened to 45 feet (13.7 m).

1987
Cairo Metro opened

The Cairo Metro is the rapid transit system in Greater Cairo, Egypt. It was the first of the three full-fledged metro systems in Africa and the first in the Middle East to be constructed. It was opened in 1987 as Line 1 from Helwan to Ramses Square with a length of 29 kilometres (18.0 mi). As of 2013, the metro carried nearly 4 million passengers per day. As of October 2022, the Cairo Metro has 74 stations of which 4 are transfer stations, with a total length of 93.1 kilometres (57.8 mi). The system consists of three operational lines numbered 1 to 3.

1981
TGV opened

The TGV (French: Train à Grande Vitesse, "high-speed train") is France's intercity high-speed rail service. The TGV opened to the public between Paris and Lyon on 27 September 1981. Contrary to its earlier fast services, SNCF intended TGV service for all types of passengers, with the same initial ticket price as trains on the parallel conventional line.

1965

1940 Tacoma Narrows Bridge construction started

The 1940 Tacoma Narrows Bridge, the first bridge at this location, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. The bridge's collapse has been described as "spectacular" and in subsequent decades has attracted the attention of engineers, physicists, and mathematicians. Throughout its short existence, it was the world's third-longest suspension bridge by main span, behind the Golden Gate Bridge and the George Washington Bridge.
