Padma Bridge construction started
The Padma Multipurpose Bridge is a two-level road-rail bridge across the Padma River, the main distributary of the Ganges in Bangladesh. The bridge consists of 41 sections, each 150.12 m (492.5 ft) long and 22 metres (72 ft) wide, with a total length of 6.15 km (3.82 mi). It is the longest bridge in Bangladesh, the longest bridge over the river Ganges by both span and total length, and features the highest pile depth of any bridge in the world at 120 m (390 ft). It is the deepest bridge in the world, with piles installed as deep as 127 metres. The construction of the bridge was considered to be especially challenging due to width and depth of the Padma River.
Daegu Metro opened
Daegu Metro is a metro system that serves primarily the South Korean city of Daegu. With the fastest track speed at 80 km/h (50 mph), it takes 55 minutes for Line 1 and Line 2, and 48 minutes for Line 3 to reach the terminus station. As of 2015, the number of average daily passengers is 186,992 people for Line 1, 177,984 people for Line 2, and 69,127 people for Line 3.
King Fahd Causeway opened
The King Fahd Causeway is a 25 km (15.5 mi) long series of bridges and causeways connecting Khobar, Saudi Arabia, and Al Jasra, Bahrain. Its five bridges rest on 536 concrete pylons, with seven embankments in the Gulf's shallower water. One of the embankments, known as Middle Island has been converted into a sizeable artificial island with customs and immigration facilities, a mosque and gardens and fast food restaurants. Another island towards the end of the causeway belongs to Bahrain and is simply known as Mother of Sleepiness.
Marseille Metro opened
The Marseille Metro is a rapid transit system serving Marseille, in Southern France. As of 2020, the system comprises two lines, partly underground, serving 31 stations, with an overall route length of 22.7 kilometres (14.1 mi). Line 1 opened in 1977, followed by Line 2 in 1984. Two stations, Saint-Charles and Castellane, each provide interchange between lines.
John Loudon McAdam died
John Loudon McAdam was a Scottish civil engineer and road-builder. He invented a new process, "macadamisation", for building roads with a smooth hard surface, using controlled materials of mixed particle size and predetermined structure, that would be more durable and less muddy than soil-based tracks. Modern road construction still reflects McAdam's influence. Of subsequent improvements, the most significant was the introduction of tar (originally coal tar) to bind the road surface's stones together, "tarmac" (for Tar Macadam.)
