Retractable Bridges
A retractable bridge is a type of movable bridge, moveable bridge in which the deck can be rolled or slid backwards to open a gap while traffic crosses, usually a ship on a waterway. This type is sometimes referred to as a thrust bridge. Retractable bridges date back to medieval times. Due to the large dedicated area required for this type of bridge, this design is not common. A retractable design may be considered when the maximum horizontal clearance is required (for example, over a canal). Two remaining examples exist in New York City: the Carroll Street Bridge (built 1889) in Brooklyn, and the Borden Avenue Bridge in Queens. A recent example can be found at Queen Alexandra Dock in Cardiff, Wales, where the bridge is jacked upwards before being rolled on wheels. Helix Bridge at Paddington Basin in London is a more unusual example of the type, consisting of a glass shell supported in a helical steel frame, which rotates as it retracts.

Fort Point Channel
Fort Point Channel is a maritime channel separating South Boston from downtown Boston, Massachusetts, feeding into Boston Harbor. The south part of it has been gradually filled in for use by the South Bay rail yard and several highways (specifically the Central Artery and the Southeast Expressway). At its south end, the channel once widened into South Bay, from which the Roxbury Canal continued southwest where the Massachusetts Avenue Connector is now. The Boston Tea Party occurred at its northern end. The channel is surrounded by the Fort Point neighborhood, which is also named after the same colonial-era fort. The banks of the channel are still busy with activity. South of Summer Street on the west side of the channel is a large United States Postal Service facility. A large parcel, home to Gillette, lies at the southeast corner of the channel.

Berbice Bridge
The Berbice Bridge is a pontoon bridge over the Berbice River near New Amsterdam in Guyana. The bridge is tolled and was opened on 23 December 2008. With the completion of the Berbice Bridge, and the earlier completion of the Coppename Bridge in Suriname in 1999, the Courantyne River is the only river between the Guyanese capital of Georgetown and the Surinamese capital of Paramaribo still left without a bridge. This is due to change in the near future, with plans for a bridge on the Courantyne near South Drain. The bridge doesn't have a pedestrian crossing. It is owned by Berbice Bridge Company Incorporated and tolls are set by a Concession Agreement between the government and the company. In 2018, the government took over ownership of the bridge as a reaction to the 360% increase in toll, citing Sections 4 (1) and 11 of the Berbice River Bridge Act in the interest of public safety.

The bridge crosses the Demerara River south of the Guyanese capital Georgetown, from Peter's Hall, Demerara-Mahaica, East Bank Demerara to Schoon Ord, Essequibo Islands-West Demerara, West Bank Demerara. There is a pedestrian footwalk. A raised section lets small vessels pass under. A retractor span lets large vessels pass. The bridge has 61 spans. A high-level span provides a horizontal clearance of 32.0 metres (105 ft) and a vertical clearance of 7.9 metres (26 ft) to let small craft pass at all times. To let large craft pass, two retractor spans retract fully once per day to leave a horizontal clearance of 77.4 metres (254 ft). The number vehicles transiting per day was approximately 9,000 in 2015, and 14,000 . Although the bridge was designed to last ten years, it has been so successful that it has inspired the Berbice Bridge, completed in 2008. History Co ...
