This is one of three nearly identical pumping stations that drained the Haarlemmermeer (Haarlem Lake), 1849- 52, then continued to maintain the polder's water table for more than 80 years. The Haarlemmermeer area covers 45,000 acres (about 70 square miles) in a triangular region between the cities of Amsterdam, Haarlem, and Leiden.

Conwy Tubular Bridge
Society: ASCE Main Category: Civil Sub Category: Bridges, Roads & Rails Era: 1840-1849 DateCreated: 1849 River Conwy State: North Whales Zip: Country: UK Website: Creator: Stephenson, Robert

Built by Robert Stephenson to carry the Chester and Holyhead Railway across the River Conwy, this bridge was erected between 1846 and 1848. It consists of a single span 400 feet long, formed by two parallel rectangular wrought iron tubes, each weighing 1300 tons. Masonry towers were built on the abutments and topped with battlements and turrets to harmonize with the nearby Conwy Castle. The Conwy Tubular Bridge was the first railway bridge in which trains ran through the main girders. It represents a pioneering use of wrought iron for bridges.
