Jiaxing-Shaoxing Sea Bridge opened

The Jiaxing-Shaoxing Sea Bridge, sometimes shortened to Jiashao Bridge, is the world's longest and widest multi-pylon cable-stayed bridge. From end to end, it stretches 10.14 km (6.3 mi) across the Qiantang River estuary, at Shaoxing, Zhejiang, China. The main bridge is 2,680 m (8,790 ft) long and 55.6 m (182 ft) wide and carries an expressway with eight traffic lanes. Jiashao is the second sea-crossing bridge built in the greater Hangzhou Bay area. It is about 50 km (31 mi) west of the longer 35.67 km (22.2 mi) Hangzhou Bay Bridge, which opened May 2008, a half year before construction began on the Jiashao.

Arroyo Seco Parkway opened

The Arroyo Seco Parkway, also known as the Pasadena Freeway, is one of the oldest freeways built in the United States. It connects Los Angeles with Pasadena alongside the Arroyo Seco seasonal river. It is notable not only for being an early freeway, mostly opened in 1940, but for representing the transitional phase between early parkways and modern freeways. The first contract, stretching less than a mile (1.5 km) from Glenarm Street in Pasadena around Raymond Hill to Fair Oaks Avenue in South Pasadena, and including no bridges, was opened to traffic on December 10, 1938. A 3.7-mile (6.0 km) section opened on July 20, 1940, connecting Orange Grove Avenue in South Pasadena with Avenue 40 in Los Angeles.
